ChicJewelryLive.com Gemstond Information
Throughout history, gemstones have been prized by royalty and worn as charms
for protection and good fortune. Over time, many gemstones have become popular
gifts for birthdays and anniversaries.
Created by nature, genuine gemstones are beautiful to gaze at and delightful to wear. At Jewelry By Net, you can be assured that you are purchasing the highest quality gemstones at the best possible price to treasure for yourself or to give as a gift.
Created and Enhanced Gemstones
Lab-Created
One of the most popular types of gems is the laboratory-created gemstone. Lab-created
gems have the identical chemical composition, crystal structure and appearance
of their natural counterparts created by Mother Nature. Because they are
made in a laboratory, lab-created gemstones are almost perfect. They are
also more affordable than rare, natural gemstones. The most common lab-created
gems are emeralds, rubies, sapphires and opals.
Simulated
Simulated gems resemble real gemstones but are made from other natural and
synthetic materials and cost much less. Cubic zirconia, which looks like
a diamond, is an example of a simulated stone.
Enhanced
Nearly all gemstones available today have been enhanced to bring out their
best color or to strengthen them. For example, an accepted industry practice
in the polishing process for sapphires involves heating the stones to bring
out their color. This process simply extends what nature began, since it
is heat and pressure that give gemstones their color in the first place.
Before You Buy Your Gemstones
What could be more tempting than a jewelry display packed with a rainbow of brightly colored gemstones? Go shopping and you'll see natural, synthetic, and imitation stones of every color, shape, and size. Can you tell one type of stone from another? Here are some tips to help you understand the differences so you can ask the right questions before you buy a colored gemstone.
Natural Colored Gemstones
Natural stones are courtesy of nature, with no interference from humans. Don't assume that just because it's natural a stone should carry a high price tag. Prices are driven by desirability, quality, and availability. A brilliantly colored ruby with "perfect" clarity will cost thousands of dollars more than a garnet of similar quality. Become acquainted with the gemstone market before you buy.
Gemstone Treatments
Most natural stones are treated to improve appearance. Heat and radiation change or enhance colors. Diffusion deepens color, but only within a stone's outer layers. Oil and waxes are used to fill-in surface-breaking fractures. Some treatments are permanent--others are not. Treated gems can be a good choice when you know what you are buying and pay a price that reflects a stone's true quality.
Synthetic Colored Gemstones
A synthetic stone shares a natural stone's physical, chemical, and optical qualities. The difference? Synthetics are created in a lab. They've been around for a long time, but modern technology allows us to grow stones that are difficult to distinguish from their natural counterparts. Ask for a lab certificate to verify authenticity before paying top dollar for a stone represented as natural.
Imitation Stones
Imitation, or simulated, stones may at first look like the real thing, but
that's where the similarities end. They do not share physical characteristics
with natural or synthetic stones. Many are made of glass or plastic and most
can be detected easily by a jeweler. Moissanite is a newer diamond substitute
that's even fooling the pros.
Composite Stones
Doublets are stones that are assembled using a larger chunk of an inexpensive stone (or glass) which is topped by a thin slice of the genuine stone. The division usually isn't obvious without magnification. One type of doublet sandwiches a colored bonding agent between two clear stones to mimic a colored gemstone. Triplets are composites assembled in three parts.
Bottom Line
Imitation and synthetic stones make lovely jewelry--there's no reason to avoid them. What you do want to avoid is paying too much for a misrepresented stone. Read as many resources as possible and start looking more closely at jewelry. Ask questions when you shop. It won't make you an overnight pro, but in time it will help you become a more savvy consumer.
Different Gemstones
AMETHYST
Few gemstones have a history as rich as amethyst, the oldest gemstone used by man. Amethyst is strongly associated with the early belief that it could protect the wearer against the effects of alcohol. The name comes from the Greek word "amethystos," meaning "without drunkenness," so wine goblets often included amethyst decoration.
The amethyst has also served as a religious symbol. The stone sometimes represents Christian humility and piety, so amethyst ornamentation in churches was common, especially during the Middle Ages. Rosaries are often made using the gem, and many members of the clergy still wear amethyst jewelry. In Tibet, this gem is considered to be sacred to the Buddha.
Amethyst's most distinguishing characteristic is the color, which ranges from pale lilac to deep purple, long considered a regal color. Included in the British crown jewels, fine amethysts were also a favorite of Catherine the Great and Egyptian royalty. Most of today's supply comes from Brazil, and Zambia is also a significant source. Amethyst is the birthstone for February.
AQUAMARINE
Known as the "gem of the sea," aquamarine means "seawater." Although this gem is available in many shades, the rich, clear, watery blue stones are among the more valuable of these semiprecious gems.
Legend has it that aquamarines were treasures of mermaids with the power to keep sailors safe at sea. These gems are also thought to have a soothing influence, especially on married couples, helping them work out differences and ensure a long and happy marriage. The birthstone for March, aquamarine symbolizes youth, hope, health and fidelity.
While aquamarines can be found in many exotic places including Nigeria, Madagascar, Zambia and Mozambique, most of the gemstones available today come from Brazil.
CIRTINE
Thanks to its durability and availability, citrine is one of the most affordable gemstones. It was named from the French word "citron," meaning "lemon," because of its bright golden color. Citrine actually includes yellow to gold to orange brown shades of transparent quart. Because the yellow variety is similar in look to yellow topaz - November's birthstone - citrine is an alternative birthstone choice.
In ancient times, people revered citrine as a gift of the sun and believed the stone could provide protection against snake venom and evil thoughts. Primarily mined in Brazil, this gem is popular in many jewelry styles, particularly when set in polished yellow gold. Since most citrine on the market started its life as amethyst that was heated to turn its color to gold, citrine jewelry should be kept away from prolonged exposure to strong light or heat.
Emeralds, the May Birthstone
Prized since ancient times, a fine emerald can be more expensive than a high quality diamond of the same carat weight. Emerald is a form of Beryl, which occurs in many other colors depending on the impurities that Mother Nature has mixed into its otherwise clear formula. Blue beryl is known as aquamarine. Pink shades of beryl are known as Morganite. Yellows are often just called yellow beryl and golden beryl. The term bixbite refers to red beryl, a variation that's even more rare than emeralds.

EMERALD
The name of the emerald comes from the Greek word "smaragdus," which means "green." Ancient Egyptians first mined emeralds more than 4,000 years ago, and Cleopatra was an avid collector. During the 16th Century, Spanish explorers discovered bountiful deposits of South American emeralds during their interactions with the Aztecs and Incas. The brightest and most colorful emeralds still come from South America, with those mined in Colombia considered the best quality.
Like other gems, the emerald has its own set of mystical powers. Emeralds have long symbolized fertility, rebirth and springtime. The birthstone for May, emerald is believed to be a good luck charm, bringing wearers sharpened wit, wealth, good health and the ability to see the future.
Almost all emeralds have inclusions; however, the fewer in number, the more valuable the stone. The inclusions can make emeralds brittle, so protect your emeralds from hard contact including ultrasonic cleaners, whose vibrations can damage heavily included stones. If your stone has been waxed or oiled to smooth or fill thin scratches and fissures commonly found in natural emeralds, you may need to have the stone re-oiled or waxed professionally every few years.
Emeralds are the May Birthstone
Prized since ancient times, a fine emerald can be more expensive than a high
quality diamond of the same carat weight.
Emeralds are green members of the popular beryl family of minerals. The green
color occurs when pure, clear beryl contains either chromium or vanadium.
Beryl occurs in many other colors, with shades dependent on the impurities that Mother Nature has mixed into its otherwise clear formula. Blue beryl is known as aquamarine. Pink shades of beryl are known as Morganite. Yellows are often simply called yellow beryl and golden beryl. The term bixbite refers to red beryl, a variation that's even more rare than emeralds.

Emerald Facts
Emerald hardness on the Mohs scale ranges from 7.5 to 8. As a reference, turquoise ranges from 5 to 6; diamonds are the hardest substance, at 10. Even though emeralds are relatively hard stones, the presence of cracks and inclusions can affect their durability.
Emerald is the birthstone for May and is the traditional gift for the 55th wedding anniversary.
Colombian emeralds are among the world's most beautiful, with rich grass-green coloring that's often kissed with a touch of blue. Quality emeralds are also found in India, South Africa, Afghanistan, Pakistan, Russia, and Zimbabwe. Recent finds in North Carolina may provide us with quality emeralds if the mine continues to produce stones.
Emerald History and Folklore
Emeralds are traditionally thought to enhance the clairvoyance of their wearers.
Egyptian emeralds were introduced to the world about 4,000 years ago, but the stones from those mines are a duller green and are not considered high quality by today's standards.
Mummies were often buried with emeralds and the gems were popular in ancient Rome, but some think that many of the stones called emeralds in ancient times were actually peridot.
Traditionally, emeralds are worn to promote healing and enhance love and contentment.
Common Emerald Treatments
Most emeralds are treated to enhance their appearance. Even though treatments are common and accepted, they should be disclosed.
Nearly all emeralds are treated with oils or epoxy resins to fill-in surface cracks, making the cracks less visible and improving transparency.
Some oils are clear, some are tinted green to make the gems more vivid.
Most jewelers tell us to avoid cleaning emeralds with ultra-sonic devices,
because that process can remove coatings.

When It's Too Good To Be True
When high-demand gemstones are scarce and costly, humans attempt to create products that look like the real thing. Emeralds can be lab-grown synthetics, which do have the same chemical composition as a stone grown in nature, or they can be genuine stones combined in ways that make a small sliver of gem look like a larger specimen. What you think is an emerald might even be a fake made of glass or another material.
Synthetic Emeralds. The way they are grown has changed, but synthetic emeralds have been produced for many years. Some of the stones even have inclusions that make them look natural. Some dealers may claim a synthetic is "real," and that is technically correct, since true synthetic gems have the same chemical characteristics as their natural counterparts, but a reputable jeweler will disclose that a gem is lab-grown. Always ask if gemstones are created or natural, and if you are buying an expensive stone, have it checked by a lab.
Composite Stones A composite is a smaller piece of a desirable, genuine stone that's been combined with a larger chunk of an inexpensive or imitation gemstone. It's often difficult to detect these stones without magnification... More About Composite Gems and Other Deceptions
GARNET
While garnet is often seen as a ruby substitute, it can be appreciated for its wide selection of colors (including shades of red, orange, green and pink) and different varieties (like rhodalite, demantoid and malaya). Garnet is the birthstone for January, and any of the stone's colors or varieties is acceptable for use as a birthstone. Because of its durable nature, garnet is ideal for jewelry. In fact, the stone's first use as a gemstone dates back to 3100 B.C. However, the demantoid variety is softer and should be protected from sharp blows.
This gem symbolizes loyalty and energy. Like many red stones, garnet was once believed to stop bleeding. However, the stone's color was also thought to increase the severity of wounds, so garnet was used to make bullets in ancient Asia and the American Southwest. Its powers were also said to alleviate anger, promote tranquility, and offer protection in health and travel. Many believed that garnet had illuminative powers, both physically and spiritually, and served to protect wearers from nightmares.
IOLITE
Because of its striking color, iolite is becoming a popular gemstone. The name comes from the Greek word "ios," meaning "violet," and the gem is usually purplish blue. When cut properly, an iolite cube will look violet-blue from one side, clear as water from the other, and honey yellow from the top. This property, known as pleochrism, made iolite a valuable tool for Viking explorers. They used thin pieces of iolite to block the sun's glare to determine its exact position in order to return home safely.
Mined in India, Sri Lanka, Africa and Brazil, iolite can be easily obtained in sizes up to five carats, although much larger stones have been found. The gem is relatively strong, but you should protect your iolite from sharp blows.
ONYX
Onyx is part of the chalcedony family of colored quartz, which includes agate, cornelian and jasper. Usually seen in solid black, some onyx has white bands or ribbons in a backdrop of black or dark brown. Because the bands can form naturally in many different ways, each piece of banded onyx has a unique appearance. The most popular onyx jewelry shape is cabochon - a smooth, polished dome - but the stone is often used to make cameos because of the contrasting layers.
Opaque stones like onyx are sometimes treated to enhance their natural color and luster. To ensure the finish remains colorfast, do not wear onyx jewelry while bathing or swimming, and avoid using chemicals, detergents, hairspray and perfume near onyx.
The myths and legends associated with onyx are varied, from a means to drive away evil and high tempers, to the ability to cool the passions of love. This gem was also believed to increase happiness and intuition, while some believed that onyx was a symbol of discord, a view probably suggested by the stone's distinct lines in the banded variety.
OPAL
October's birthstone, the opal includes the same ingredients as quartz; however, each stone also contains between 6 and 10 percent of water that has not been compressed into crystals. As a result, opal is softer than quartz and has to be treated carefully to avoid damage. This gem should be protected from extreme hot or cold temperatures and strong light to prevent drying out and cracking. Use only a soft cloth to clean your opals, and avoid ultrasonic cleaners, metal polish, acids and strong solvents, which can all damage this stone.
The shifting colors of opal, known as "fire," are the result of microscopic spherical structures within the stone. The structures reflect different wavelengths of light depending on their spacing, creating the opal's shimmering effect. Opal comes in three varieties: black, white and crystal, which is transparent. The non-transparent stones are usually cut into cabochons (smooth, polished domes). Today's supplies come from Australia, Mexico and the United States.
Throughout history, kings and queens have treasured opals. The Holy Roman Emperor's crown included an opal called the orphanus, and the stone was said the guard the regal honor. The crown jewels of France contain opals, and Emperor Napoleon gave Josephine an opal with red flashes, known as "The Burning of Troy." Also an admirer, Queen Victoria gave opals as wedding gifts, and she and her daughters made them fashionable by wearing them.
Some legends say that opals have the power to improve vision and ward off eye troubles. These jewels also have a reputation for sharpening the mind and emotions. Opals symbolize fidelity, but are said to bring trouble to an unfaithful person.
PERIDOT
Peridot is the August birthstone, but the bright green gem is popular with people born in any month of the year. It looks good combined with many other gems, especially pearls, diamonds and turquoise.
Peridot is an ancient stone, used in Egypt for beads as early as 1580 B.C. Known as the "gem of the sun," the gem ranges in color from yellow green to chartreuse. Under artificial light, peridot appears greener, prompting ancient Romans to name it "evening emerald."
According to Hawaiian legend, peridots were divine tears wept by Pele, goddess of the volcano. The stone was supposed to protect wearers from nightmares and evil spirits, and peridot's ability to drive away evil was supposed to be stronger when set in gold. Other powers included the ability to cure liver disease, promote friendship, and ensure good thoughts in the mind of the wearer.
Many of the peridots mined today come from Arizona, with others coming from China and Myanmar (Burma). Because the stones have good clarity and brilliance, faceted cuts are appropriate; however, peridots are relatively soft and should be protected from damage. Peridot is the birthstone for August.
Peridot was sometimes called the evening emerald in ancient times because it resembled emeralds in the glow of burning lamps.
Gemstone treatments, fakes & composites
Most gemstones used in jewelry have been treated to improve their appearance. Treated gemstones can be a good choice when you know what you are buying and pay a price that reflects a stone's true quality.
Common Gemstone Treatments
Heat and radiation can change or enhance colors.
Diffusion is used to deepen color. It only changes a stone's outer layers.
Oil and waxes are used to enhance color by filling-in fine surface cracks.
Fracture filling, which coats stones with a clear or colored epoxy resin or other substance. This treatment fills-in cracks, which improves the appearance of the stone.
Laser drilling removes inclusions (flaws), improving clarity.
Some gemstone treatments are permanent, others are not. Heat treatments create permanent color changes in some stones, but temporary changes in others. Always ask if the jewelry you intend to purchase contains treated gemstones. If it does, ask which treatments were used and if those treatments are permanent.
Imitation Gemstones
Imitation, or simulated, stones may look like the real thing, but that's where the similarities end. They do not have any of the same physical characteristics of a natural or synthetic gemstone.
Imitation stones are often made of glass or plastic and most can be detected easily by a jeweler.
A stone that's mounted on a solid back might have foil underneath to make it look more brilliant or change its color.
Moissanite is a newer diamond substitute that's even fooling the pros. It is not a fake—it is a synthetic version gemstone that's only been found in very small quantities in nature.
It's a problem when moissanite or other substance that resembles a similar gem is resold as the more expensive gemstone by someone who either doesn't know the difference, or intends to deceive.
Watch for Composite Stones
A composite is a smaller piece of a desirable, genuine stone that's been combined with a larger chunk of an inexpensive or imitation gemstone.
Doublets are composite stones where a larger, inexpensive chunk is topped by a thin slice of a genuine stone. The division usually isn't obvious without magnification.
One type of doublet sandwiches a colored bonding agent between two clear, inexpensive stones to mimic a colored gemstone.
Triplets are composites assembled in three parts.
Be a Careful Shopper
Jewelry made with synthetic, treated, and imitation stones can be gorgeous—there's no reason to avoid it. What you do want to avoid is paying too much for misrepresented merchandise.
Read as many resources as possible and start looking more closely at jewelry. Ask questions when you shop. It won't make you an overnight pro, but in time it will help you become a more savvy consumer.
RUBY
Along with emerald and sapphire, ruby is one of the most prized gems. Early admirers thought its bright red color came from an undying flame inside the stone or from a piece of the planet Mars. The name ruby actually comes from the Latin word for red, and the gem's beauty earned the nickname of "Ratharaj," or King of Gems, from the ancient Sinhalese people.
In addition to its status as a love symbol, rubies are thought to bring protection to the wearer. The stones were also thought to stop bleeding, and ancient Burmese people believed they would be invincible if rubies were embedded in their skin.
Both ruby and its sister stone, sapphire, are from the corundum mineral species, but only the red variety is called ruby. All other colored corundums are known as sapphires. Rubies are durable - the second hardest mineral after diamonds. They are mined throughout Southeast Asia, and the best-colored stones come from Myanmar (Burma). Ruby is the birthstone for July.
SAPPHIRE
Although its name comes from the Latin word "sapphiru," meaning "blue," sapphire actually refers to any colored gemstone from the corundum mineral family except red. The most popular and well-known sapphire color is blue, and ancient Persian rulers believed that the color of the heavens was a reflection of the sapphire's color. This gemstone is also available in other colors like pink, orange, lavender, green and yellow - known as fancy sapphires.
Thought to be a mind-opening gem, sapphires are said to bring wearers to a more relaxed state and promote clear thoughts. Sapphires are also supposed to protect wearers from envy and fraud, bring truth and good health, and act as an antidote for poison.
The birthstone for September, sapphire is identical in chemical makeup to its red counterpart, the ruby, which means it is very durable. While sapphire is found in many parts of the world, the most prized stones come from Myanmar (Burma), Kashmir and Sri Lanka.
TOPAZ
Topaz occurs in an array of colors from blue, red, orange, peach, pink, gold and yellow. The gem was first discovered in Brazil, and the pink and cognac-colored stones were worn by Russian czarinas, earning the stones the name "Imperial Topaz." Today, topaz is found in Brazil, Mexico, Sri Lanka, Africa and China.
Egyptians believed that the golden glow of topaz came from the mighty sun god Ra, and the gem was a powerful charm to protect the faithful from harm. Ancient Romans associated topaz with their sun god, Jupiter, while ancient Greeks believed that the stone made wearers stronger and even invisible during an emergency.
Topaz myths are numerous. In the Middle Ages, topaz was believed to have incredible medicinal powers, even protecting people against the plague. For healthy people, the jewel brought a pleasant disposition and patience, and was a symbol of fidelity and love. Topaz also lead to clear physical and mental sight by dispelling enchantment and improving eyesight.
This gem is very hard, but similar to diamond in that topaz can be split with a single blow. As a result, you should protect your stone from hard knocks. Yellow topaz is the birthstone for November, and blue topaz is December's birthstone.
TOURMALINE
Tourmalines are named from the Sinhalese word "turmali," which means "many colors." Available in more shades than any other gemstone, tourmalines can include as many as three separate colors in one stone. In fact, a tourmaline can be found to match almost every other gem. For example, the Russian crown jewels contain many tourmalines once thought to be rubies. Also popular are the bicolor and tricolor tourmalines, which have varying patterns - sometimes the different colors are at the ends of the crystal, or the color at the center of the crystal can be different from the outside. One popular stone is pink at the center with green on the outside. Called a "watermelon" tourmaline for obvious reasons, this stone is sometimes cut in slices rather than facets.
The last Empress of China, the Empress Dowager Tz'u Hsi, valued pink tourmalines more than any other gemstone, buying nearly a ton of them from the Himalayan Mine in California. She was even buried with her head resting on a pillow carved from pink tourmaline. Scientists were also fascinated with tourmaline because it changes its electrical charge when heated, becoming a polarized crystalline magnet.
Tourmaline is mined in many parts of the world including Brazil, Afghanistan, East Africa and the United States. Although the gem is durable, avoid steam cleaning and heat.
COLORED GEMSTONE CARE
To keep your colored gemstones at their best, follow a few simple steps:
Put on your jewelry after using makeup, perfume or cologne, and hair products.
Before storage, wipe gemstones with a clean, soft, damp cloth and gently pat
dry.
Avoid exposure to hairspray, perfume, chlorine and perspiration, which can
dull gemstones.
Use mild soap and warm water to clean most stones.
Do not use toothpaste or any other abrasive cleaner on stones or mounting.
Use a soft toothbrush to gently scrub your jewelry.
Never use boiling or hot water to clean gems.
Do not wear jewelry while doing household chores.
Wrap each piece in soft tissue or cloth to prevent damage during storage.
ULTRASONIC CLEANERS
These are machines that clean jewelry by bombarding it with sound waves. This vibration shakes off dirt, but the vibrations can also cause damage to the gemstone, especially brittle stones like emeralds. Any stone inclusions can be greatly enlarged by the shaking, making the gem less attractive and valuable. Because of the risk, we recommend caution when using the ultrasonic cleaners.
