Add More Color to Your Life
…….With Natural Colored Gemstones
Morganite
Morganite (Also called pink Beryl.) Soft pink to violet, also salmon-colored. Inclusions are rare. Named after the American banker and collector J.P Morgan.
Garnet -January
Garnet traces its roots to the Nile Delta in 3100 B.C., where Egyptian artisans would craft the gemstone into beads or inlay them into hand-wrought jewelry. Noah used garnet as a lamp on his bow as he cast about on the ocean. Garnet received its name from the ancient Greeks because the color reminded them of the "granatum," or pomegranate seed.The versatile garnet comes in a virtual rainbow of colors, from the deep red Bohemian Garnet to the vibrant greens of the Russian demantoid and African tsavorite. The oranges and browns of spessartite and hessonite hail from Namibia and Sri Lanka and the subtle pinks and purples of the rhododendron flower, are also yours to explore.Garnet is the traditional birthstone for the month of January, however, red need not be your color of choice if you are born in this month. Rich orange and golden hues, striking greens, petal soft colors of violet and lavender, all await your selection.Most commonly found in round, oval, and cushion cuts. Availability depends on variety: tsavorite is very difficult to find in sizes above a carat or two, while rhodolite garnet is available in larger sizes.This durable and brilliant gem is easy to care for with mild dish soap: use a toothbrush to scrub behind the gemstone where dust can collect.
Amethyst-February
Quartz is found in abundance from every corner of the earth. In its purest form, quartz is colorless, but is most prized for its purple variety- amethyst. Purple has long been considered a royal color, so it is not surprising that amethyst has been so much in demand throughout history. Fine amethysts are featured in the British Crown Jewels and were also a favorite of Catherine the Great and Egyptian royalty. Great thinkers like Leonardo da Vinci believed that amethyst could dissipate evil thoughts and quicken the intelligence. Amethyst, the traditional birthstone for the month of February, is available in small and large sizes, although as with all gemstones, very large sizes in rich, deep colors have always been rare. Designers celebrate amethyst as the ideal choice for jewelry because of its regal color, variety of sizes and shapes, affordability and wide tonal range from light to dark purple. Brazil is the primary source of amethyst, and Zambia is a significant source as well. Darker hues of amethyst are rarely enhanced to perfect their color, although some varieties do respond well to heat enhancement.
Aquamarine-March
The very name aquamarine brings to mind the limpid, clear blue tint of the sea. Legend says that Neptune, the King of the Sea, gave aquamarine as gifts to the mermaids, and from then on, it has brought love to all who have owned it. Aquamarine was long thought to have a soothing influence on married couples, making it a good anniversary gift. Aquamarines are found in a range of blue shades, from the palest pastel to greenish-blue to a deep blue. While the choice of color is largely a matter of taste, the deeper blue gemstones are more rare. Remember that Aquamarine is a pastel gemstone, and while color can be quite intense in larger gemstones, the smaller aquamarines are often less vivid. This elegant colored gemstone is the birthstone of March and is the symbol of youth, hope, health and fidelity. Aquamarine was long thought to have a soothing influence on married couples, making it a good anniversary gift.
Aquamarines are mined in a number of exotic places including Nigeria, Madagascar, Zambia, Pakistan and Mozambique, but most of the gemstones available today come from Brazil. Many aquamarines are greenish when mined and cut. For those who prefer a purer blue, these gemstones are heated to enhance their blue color permanently. Some aquamarine fanciers prefer the greenish hues, saying the greener tones remind them more of the sea. The color tones of aquamarine are subtle and varied. Their soft luster is a wonderful addition to any natural colored gemstone jewelry collection.
Diamond-April
Diamond
Derived from the Latin diamas meaning the unconquerable, diamond has maintained its position throughout history as a perfect icon for love and marriage. Although colorless is the most common, diamond actually comes in a variety of colorful hues including yellow, pink, blue, green, brown and black.
April’s birthstone, diamond is the favored gift for the 10th and 60th wedding anniversaries. Symbolizing lasting love and friendship, Diamond was believed to inspire loyalty, rouse romance and encourage a joyful life. The gem of character and spirit, diamond radiates the dazzling personality of those who wear it.
Fancy yellow and pink diamonds have become a popular choices for bridal rings, commanding high prices for vivid hues in fine quality. Naturally occuring fancy colored diamonds are typically more rare than colorless varieties, with red being the most uncommon, and therefore most expensive followed by blue and then green. Value is not only based on availability, but also intensity of color, clarity (the lack of inclusions) and size.
Some diamonds are heated and/or irradiated to induce fancy colors. Others may undergo high-pressure, high temperature enhancement to improve color and brilliance. To clean diamond, use warm soapy water, rinse well and pat dry to avoid residue. Mild solvents, ammonia-based cleaning agents and mechanical cleansers are generally safe. Ask your jeweler for details regarding special enhancements and care.
Emerald-May
The ancient Egyptians mined emeralds nearly 4,000 years ago, and Cleopatra was an avid collector. South America's rich bounty of emeralds was discovered by 16th Century Spanish explorers who found large emeralds in the possession of the Aztecs and Incas. Believed by the ancients to empower the owner with foresight into the future, emerald is regarded as an amulet for good fortune Emerald, to many, symbolizes rebirth and the abundance of the life force. The rich green hue brings to mind the regeneration of life in spring and hope of new possibilities. Emerald is the birthstone for May and a talisman for Gemini. Spring can also be seen in the network of inclusions in the depth of the emerald that the French call the jardin, or garden, because it resembles foliage. The inclusions are like a fingerprint, giving each emerald a distinct personality and distinguishing them as truly natural gemstones. Today, most of the world's emeralds are mined in Colombia, Brazil and Zambia. Emeralds can be cut in a variety of different shapes, ranging from the traditional rectangular step-cut, known as the "emerald cut," to rounds, ovals, squares and cabochons. Early gemstone merchants sought to purify the transparency of their emeralds by immersing them in clear oils or paraffin. They found that clear oils and waxes rendered surface fissures less visible to the eye. Today, we have many sophisticated technologies with which to clarity-enhance emeralds. In addition to the oils and waxes of ancient methods, we now use clear resins to penetrate the open fissures surfacing in the stones. Hardeners are often added to solidify these liquids. This step prevents the resin from evaporating, thus making the clarity enhancement more permanent than oiling or waxing the gem. Although emerald itself is quite durable, the garden of inclusions may make individual gems vulnerable to damage if handled roughly.
Alexandrite-June
if you love magic, especially the magic of science, you'll love alexandrite, the color-change gem, Outside in daylight it is a cool bluish mossy green. Inside lamplight, it is a red gem, with a warm raspberry tone. You can watch it flick back and forth by switching from fluorescent to incandescent light. Alexandrite is a gem variety of the mineral chrysoberyl discovered in 1830 in Czarist Russia. Since the old Russian imperial colors are red and green, it was named after Czar Alexander II on the occasion of his coming of age. Today, fine alexandrite is most often found in period jewelry since newly-mined gems are extremely rare. You'll see fine gems offered at auction with impressive estimates. The original source in Russia's Ural Mountains has long since closed after producing for only a few decades and only a few gemstones can be found on the market today. Material with a certificate of Russian origin is still particularly valed by the trade. Some alexandrite is found in Sri Lanka, Zimbabwe And Brazil, but bery little shows a dramtic color change. For many years alexandirte wasalmost impossible to find because there was so little abailable. Then in 1987, a new find of alexandrite was made in Brazil at a locality called Hemaita. The Gematita alexandrite shows a striking and attractive color change from raspberry red to bluish green. Although alexandrite remains extremely rare and expensive, the production of a limited amount of new material means a new generation of jewelers and collectors have been exposed to this beautiful gemstone, creating an upsurge in popularity and demand
Pearl-June
According to ancient Chinese legend, the moon holds the power to create pearls, instilling them with its celestial glow and mystery. Pearls have been treasured for their lustrous, creamy texture and subtle iridescent reflections since the dawn of humankind. Pearls are unique in the world of colored gemstones since they are the only gemstone formed within a living creature. Because natural pearls are so rare and difficult to recover from the ocean's depths, man invented the technique of culturing salt and freshwater pearls from mollusks carefully seeded with irritants similar to those produced by nature. The painstaking effort of culturing is one of the most dramatic examples of man's quest to coax beauty from nature. Today, cultured pearls are grown and harvested in many parts of the world including the fresh waters of the Tennessee River. The majority of cultured pearls come from Japan, China and the South Pacific. Cultured pearls come in many beautiful colors including: gold, yellow, champagne, pink, peach, lavender, gray and black. Cultured pearls come in many shapes and sizes, and can be acquired in both graduated and uniform strands. They can be purchased singly or in pairs for rings, pendants and earrings. June birthdays and third and thirtieth anniversaries are celebrated with the gift of pearls. Due to demand for perfectly matched white pearl strands, cultured fresh and saltwater pearls are often bleached to achieve a uniform color. They may also be polished in tumblers to clean and improve their luster. Dyes, heat treatment, and irradiation are sometimes applied to produce a wide range of hues such as yellow, green, blue, purple, gray, and black in freshwater and Akoya cultured pearls. Some South Sea cultured pearls are bleached to lighten their hue, but most South Sea and Tahitian cultured pearls are not subjected to enhancements to create or improve their color. Pearls require special care because they contain calcareous crystals that are sensitive to chemicals and acids. To care for your cultured pearls, avoid using perfume, hairspray, abrasives, solvents, and nail polish removers while wearing them. Like your skin, cultured pearls contain water and may dehydrate and crack if exposed continuously to arid conditions.
Ruby-July
Celebrated in the Bible and in ancient Sanskrit writings as the most precious of all gemstones, rubies have been the prized possession of emperors and kings throughout the ages. Ruby's inner fire has been the inspiration for innumerable legends and myths, and to this day, no red gemstone can compare to its fiery, rich hues. It was believed wearing a fine red ruby bestowed good fortune on its owner - although the owner must have already had good fortune enough to possess such a rare and beautiful gemstone! Many people associate its brilliant crimson colors with passion and love, making ruby an ideal choice for an engagement ring. Ruby is the red variety of the corundum mineral species, while all other colors of corundum are called sapphire. This most sought after gemstone is available in a range of red hues, from purplish and bluish red to orangish red. Ruby is readily available in sizes up to 2 carats, but larger sizes can be obtained. However, in its finest quality, any size ruby can be scare. In readily available small sizes, ruby makes an excellent accent gemstone because of its intense, pure red color Ruby is mined throughout Southeast Asia. While Thailand and Myanmar (Burma) produce exquisite examples of this gemstone that the ancient Sinhalese people called "Ratnaraj," the King of Gemstones. Despite all the best efforts of gemstone merchants to use technology to enrich color, fine ruby is still exceptionally rare. After being extracted from the earth, rubies today are commonly heated to high temperatures to maximize the purity and intensity of their red hue. Impurities may also dissolve or become less noticeable after heating. However, heating will only improve the color if the gemstone already contains the chemistry required. Occasionally rubies with small imperfections are permeated with a silicate byproduct of the heating process, which helps to make small fissures less visible. This enhancement, like heating, is permanent and rubies, whether enhanced or not, remain among the most durable of gems. Today a new method of artificially coloring the surface of paler rubies through the diffusion of beryllium, or a similar element, has made the red of ruby more affordable. Although this method is not yet common, in the future beryllium-diffused rubies may offer an affordable alternative to either untreated or heat-enhanced rubies, which are both much more rare. However, recutting or repolishing may affect the color of some beryllium-diffusion treated rubies.
Peridot-August
Peridot is treasured in Hawaii as the goddess Pele's tears. The island of Oahu even has beaches made out of tiny grains of peridot. Although Hawaii’s volcanoes have produced some peridot large enough to be cut into gemstones, virtually all peridot sold in Hawaii today is from Arizona, another state with extreme geology. The fresh lime green of peridot is its distinctive signature. Its spring green color also is ideal with sky blue. Today most peridot is mined, often by hand, by Native Americans on the San Carlos Reservation in Arizona. Peridot found here is beautiful in color but relatively small in size. Faceted peridot from Arizona is rare in sizes above five carats. Fine large peridot are found in Burma and large quantities of peridot are also mined in China. In 1994, an exciting new deposit of fine peridot was discovered in Pakistan, 15,000 feet above sea level in the far west of the Himalaya Mountains in the Pakistanian part of Kashmir.
Peridot, the birthstone for August, is harder than metal but softer than many gemstones. Store peridot jewelry with care to avoid scratches and protect from blows. Because peridot is sensitive to rapid changes in temperature, never have it steam cleaned and avoid ultrasonics. Clean with mild dish soap: use a toothbrush to scrub behind the stone where dust can collect.
Sapphire-September
Velvety blue. Liquid blue. Evening-sky blue. Cornflower blue. Sapphire, beloved for centuries as the ultimate blue gemstone. The ancient Persian rulers believed that the earth rested on a giant sapphire and its reflection colored the heavens blue. Indeed, the very name in Latin, "Sapphiru," means blue. But like the endless colors that appear in the sky, sapphire is also found in many, many other shades besides blue, from the gold of a sunrise, to the fiery reddish-orange of sunset, to the delicate violet of twilight. Sapphire may even resemble the pale white gloaming of an overcast day. These diverse colors are referred to as "fancy" color sapphires. A gift of a sapphire symbolizes a pledge of trust and loyalty. It is from this tradition that sapphire has long been a popular choice for engagement rings. One of Nature's most durable gemstones, sapphire shares this quality with its sister, the ruby. Sapphire is found in many parts of the world, but the most prized sapphires are from Myanmar (Burma), Kashmir and Sri Lanka. The purer the blue of the sapphire, the greater the price the gemstone can command, however, many people find that the darker hues of sapphire can be just as appealing. Over the centuries, methods have been developed to enhance the purest hues of sapphire. This is now commonly achieved by controlled heating, a technique that not only improves color but also improves clarity. But heating will only improve the color if the gemstone already contains the chemistry required. Heating sapphires is a permanent enhancement, as lasting as the gemstones themselves. A new method of artificially changing the natural color of a sapphire is diffusion, whereby beryllium or a similar element is diffused into the surface of the gemstone, producing a richer color. Sapphire treated by diffusion is far less costly and much more available than rare fine untreated gems or those successfully heat-treated. Diffused sapphire is available in shades of orange, pinkish orange, yellow and sometimes even blue. Information about diffusion should be provided on the invoice for your jewelry. Recutting or repolishing may affect the color of some diffusion-treated stones.
Tourmaline-October
For centuries tourmalines have adorned the jewels of royalty. The Empress Dowager Tz'u Hsi, the last empress of China, valued the rich pink colors above all other gemstones. The people of ancient Ceylon called tourmaline "turmali," the Sinhalese word for "more colors." Perhaps this is why ancient mystics believed tourmaline could encourage artistic intuition: it has the palette to express every mood. Vivid reds, hot pinks, verdant greens and blues abound in this marvelous gem variety. Earth tones as varied as a prairie sunset are readily available. Not only does tourmaline occur in a spectacular range of colors, but it also combines those colors in a single gemstone called "bi-color" or "parti-color" tourmaline. One color combination with a pink center and a green outer rim is called "watermelon" tourmaline, and is cut in thin slices similar to its namesake. Dark blue, blue-green, and green tourmalines are occasionally heated to lighten their color. Red tourmalines, also known as rubellites, and pink varieties are sometimes heated or irradiated to improve their colors. Heat and irradiation color enhancement of tourmalines is permanent.Occasionally, some tourmalines may have surface-breaking fissures that are filled with resins, with or without hardeners. Care must be observed with these gemstones. Avoid exposing them to harsh abrasives and strong chemical solvents.
Opal-October
Revered as a symbol of hope, fidelity, and purity, opal was dubbed the Queen of Gems by the ancient Romans because it encompassed the colors of all other gems. Opal is prized for its unique play of color, the ability to diffract light into flashes of rainbow color. Opal occurs in different colors, ranging from semi-transparent to opaque. The most common is white opal. Crystal or water opal has a colorless body. The most valued variety, black opal, has a dark blue, gray, or black body color. Boulder opal combines precious opal with the ironstone in which it forms. Bright yellow, orange, or red fire opal are quite different from the other varieties of opal. Their day-glo tones, which are translucent to transparent, are beautiful with or without play of color. Opal, along with tourmaline, is the birthstone for October and the suggested gift for the fourteenth anniversary. Today's supplies of opal come primarily from Australia, Mexico and the United States. Most opals are not faceted but cut into rounded or free-form cabochons that enhance their play of color. Although opal is rarely enhanced by methods other than cutting and polishing, opals can be treated to bring out their play of color. One technique is to immerse white, gray, or black opal in a sugar solution and then in strong sulfuric acid, which carbonizes with the sugar and leaves microscopic carbon specks that blacken the body color, making its flashes of color more visible. Opals can also be permeated with colorless oil, wax, resin, plastic, and hardeners to improve their appearance and durability. Occasionally, some thinner or translucent opal may be painted with a black epoxy on the backside of the gemstone to darken the body color and improve the play of color. Fire opal is not commonly enhanced. Opal, with or without enhancement, should be treated with some care. Opal is softer than many other gemstones and should be stored carefully to avoid being scratched by other jewelry. It should also be protected from blows, as exposed corners can chip. Opal should not be exposed to heat or acid.
Topaz-November
The Egyptians said that topaz was colored with the golden glow of the sun god. Legend has it that topaz dispels all enchantment and helps to improve eyesight. The ancient Greeks believed that it had the power to increase strength and make its wearer invisible in times of emergency. Early discoveries from Brazil in rich reddish cognac colors to vivid pinks, were used to grace the jewelry of the 18th and 19th Century Russian Czarinas, hence earning the moniker of "Imperial Topaz." Topaz sometimes has the amber gold of fine cognac or the blush of a peach, and all the beautiful warm browns and oranges in between. Some rare and exceptional examples are pale pink to a sherry red. Topaz is found in Brazil, Mexico, Sri Lanka, Africa and China. The birthstone for November, topaz is a talisman for the sign of Sagittarius and is the suggested gift for the 23rd anniversary. Blue, once the most rare color of topaz, is today the most common, thanks to a stable enhancement process that turns colorless topaz blue. After the raw topaz is extracted from the earth and cut, it is irradiated to brown and then heated to sky blue. This enhancement process is permanent. Due to the popularity of blue topaz, a new treatment process called vapor deposition has been developed to create additional colors of topaz. In this treatment process, similar to those used by opticians and camera makers to make lens coatings, a thin colored film is bonded on the surface of topaz to create dark blue, red, pink, and green colors or rainbow iridescence. These vapor deposition-enhanced topaz colors must be handled with special care, as the coating can be scratched or abraded. Topaz is a very hard gemstone, with a Mohs hardness of 8, but it can be split with a single sharp blow, a trait it shares with diamond. As a result it should be protected from hard knocks. Clean with mild dish soap; use a toothbrush to scrub behind the stone where dust can collect.
Citrine-November
Named from the French word for lemon, "citron" since citrine has a juicy lemon color. In ancient times, citrine was carried as a protection against snake venom and evil thoughts. Sunny and affordable, citrine can brighten almost any jewelry style, blending especially well with the yellow gleam of polished gold. It is the most affordable of all the earth-toned gemstones and is the alternate birthstone for November. Brazil and Zambia is the primary source of this gemstones. Brownish varieties are commonly heated and magically turn into the bright yellow or orange colors known as citrine. This enhancement method is permanent and will last for the life of the gemstones.
Tanzanite-December
Tanzanite is an exotic, vivid blue, kissed by purple hues. Legend has it that tanzanite was first discovered when some brown gemstone crystals lying on the dry earth were caught in a fire set by lightning that swept through the grass-covered hills. The Masai herders driving cattle in the area noticed the beautiful blue color and picked the crystals up, becoming the first tanzanite collectors. Tanzanite has the beauty, rarity and durability to rival any gemstone. It is the ultimate prize of a gemstone safari. Tanzanite is mined only in Tanzania at the feet of the majestic Mount Kilimanjaro. One of the most popular blue gemstones available today, tanzanite occurs in a variety of shapes and sizes and also provides a striking assortment of tonal qualities. Rarely pure blue, tanzanite almost always display its signature overtones of purple. In smaller sizes, tanzanite tends toward the lighter tones and the lavender color is more common. While in larger sizes, tanzanite typically displays deeper, richer color. Tanzanite is so hot, it was the first gemstone added to the birthstone list since 1912 by the American Gem Trade Association. Virtually every tanzanite is heated to permanently change its color from orange-brown to the spectacular violet-blue color for which this precious gemstone variety is known.
Zircon
In the middle ages, zircon was said to aid sleep, bring prosperity, and promote honor and wisdom in its owner. The name probably comes from the Persian word zargun which means "gold-colored." The fiery, brilliance of zircon can rival any gemstone. The affordability of its vibrant greens, sky blues, and pleasing earth tones contributes to its growing popularity today. Zircon is mined in Cambodia, Sri Lanka, Vietnam, Thailand, and other countries. Because it can be colorless, green, blue, yellow, brown, orange, dark red, and all the colors in between, it is a popular gem for connoisseurs who collect different colors or zircon from different localities. Zircon jewelry should be stored carefully because although this ancient gem is hard, facets can abrade and chip. Clean with mild dish soap: use a toothbrush to scrub behind the stone where dust can collect.
