Sterling Silver Set of 3 Gemstone Twist Rings

Caring for Sterling Silver
Sterling silver becomes tarnished as the result of a natural chemical process that occurs when sterling silver is exposed to chemicals in the air, rubber, wool and latex. Humidity also plays a role in accelerating tarnishing. It's easy to keep your sterling silver sparkling, though, by taking a few steps to prevent tarnish and other wear and tear.

Emerald
The symbol of spring and rebirth, the emerald has a color of green that communicates harmony, love of nature and a primeval joy of life. The word emerald was derived from the French “esmeraude,” which comes from the Greek root "smaragdos,” meaning simply “green gemstone.” For centuries, emerald green has been the color of beauty and eternal love. Even in ancient Rome, green was the color dedicated to Venus, goddess of love and beauty. Many cultures and religions today hold a special position for the color. For instance, green is the holy color of Islam; all states of the Arabian league sport green banners symbolizing the unity of their religion; and green is among the liturgy colors in the Catholic church. The emerald gem is May’s birthstone, and it is the traditional gift for couples celebrating their 20 th and 35 th anniversaries.

Emeralds come in a variety of light and dark shades of green, often with subtle background hues of other colors such as yellow, blue, brown or gray. Most often, the purer and richer the green color, the more valuable the stone. Flawless emeralds are exceptionally rare, and therefore command great prices (even higher than diamonds, in some instances). Most naturally grown emeralds, however, have numerous inclusions that weaken their structure and cloud their color. F laws and cloudiness, called “jardin,” are very common in emeralds, so many are treated in some way to remove surface flaws and enhance color. The most common technique is to oil the stone with a green-tinted oil that strengthens the stone and fills in surface cracks.

Emerald gemstones have been prized for thousands of years for their lush green hues and rare beauty. Venus, the goddess of love, is said to have loved the stone, and ancient Romans associated the emerald with her because it symbolized reproduction. Nero is said to have watched the Roman games in the coliseum through a set of highly prized emerald glasses. It's also said that Isis, the mother goddess, wore a green emerald on her headband. Supposedly, all who looked upon it would be able to conceive and were guaranteed a safe trip through the land of the dead. The gem is also considered the magical stone of forest spirits (elves).

In ancient Egypt, emeralds were mined close to the Red Sea. This tranquil green gem was highly prized by priests and the wealthy, and it is said that Cleopatra loved it more than any other gem. In fact, gemstone mines called “Cleopatra’s Mines” were exploited by Egyptian pharaohs between 3000 and 1500 B.C., and were found empty when they were rediscovered centuries later. Even the ancient Incas and Aztecs in South America, where the best emeralds are still found today, worshipped the emerald as a holy stone. With the conquest of South America by the Spaniards in the sixteenth century, emeralds became more plentiful in Europe. Pizarro and Cortez took over the existing emerald and gold mines of the Inca and Mayan civilizations. They shipped these fortunes back to Spain, who in turn shipped them to trading ports throughout the world, turning Spain into one of the leading world powers of the time.

Phrases about emeralds appear in the Veda, ancient sacred writings of Hinduism, including “Emeralds promise good luck” and “The emerald enhances your well-being.” Treasure chests of Indian Maharajas and Maharanis contained wonderful emeralds. One of the largest emeralds in the world is the "Mogul Emerald.” Dating back to the year 1695, it weighs 217.80 carats. One side is inscribed with prayers, while the other side is engraved with opulent flower ornaments. This legendary stone was auctioned off at Christie’s of London for 2.2 million U.S. dollars to an anonymous buyer. Other famous emeralds include a cup made from pure emerald that was owned by Emperor Jehingar. It is currently located in the New York Museum of Natural History, as is a Colombian emerald crystal weighing 632.00 carats. The entire collection is owned by the Bank of Bogota and contains five valuable emerald crystals weighing between 220.00 and 1,796.00 carats.

Throughout the ancient world, emerald symbolized eternal hope, rebirth and the arrival of spring. The ancients ascribed numerous magical and mystical properties to this most precious of green gems. It was believed to give a person psychic powers, in that the gem could tell if a lover’s affections were true. Some cultures believed the gem rewarded its owners with love, intelligence, eloquence and a soothed soul. Middle Age seers used emeralds to foretell the future, as well as to ward off evil spirits and cure ailments ranging from bad eyesight to infertility. During the Renaissance, emeralds were used as a test for friendship among the aristocracy. It was believed that an emerald given to a friend would remain perfect as long as the friendship endured. The stone was also said to improve memory and bring great wealth to its wearer.

Emeralds have long been thought to have healing powers, especially for eyesight. It is said that in business, emeralds can be used to promote sales and cash flow. It is also used to attract love by quickening the heart. The emerald is believed to put one in touch with the mind and have positive effects on psychic powers. It is said to increase those powers when used in meditation. Wearing an emerald bracelet on the left wrist is said to protect you when traveling in forests.

Brazil is by far the world's largest producer of emerald, with a wide range of quality. The finest emeralds have traditionally come from Colombia, but Russia's Ural Mountains also have produced top-quality gems. Other sources for the stone include Afghanistan, Australia, Egypt, India, Pakistan, South Africa, United States, Zambia and Zimbabwe. Emeralds belong to the beryl group of stones. They have large, perfect, six-sided crystals with a hardness of 7.0-8.0 on the Mohs Scale.

Tourmaline:
Tourmaline occurs in virtually every color of the spectrum, with an unlimited range of solid and mixed colors in all imaginable shades. According to an ancient Egyptian legend, this is the result of the gemstone traveling along a rainbow from the Earth's heart, up to the sun. On its journey, the legend says that tourmaline collected all the colors of the rainbow, which is why it is called the "Rainbow Gemstone."

The gem is found in hues of red, pink, green, blue, yellow, black, brown and colorless. It also can be bi-colored or multi-colored. Some tourmalines are very faint in color, while others are so dark that the color is only discernible when light is shone through the stone. There are even tourmalines that change their color from daylight to artificial light.

Tourmalines displaying just one color are quite rare since one crystal usually shows two or more shades or colors. In fact, the name "tourmaline" has been derived from the Singhalese expression "tura mali," which translates to "stone of mixed colors." Even two stones cut from the same rough mother crystal will often show different colors, a characteristic that makes tourmalines so attractive and sought-after.

Tourmaline also shows a remarkable dichroism. This means that when viewed from different directions, the stone will display different colors, or at least show different intensities. The deepest color always appears along the main axis, a fact that is important for the gem cutter to focus upon when cutting the stone. Tourmalines rank a hardness of 7.0-7.5 on the Mohs Scale and may be as small as a knitting needle or as thick as a thigh. They are easily available in sizes of up to 5.00ct.

Different shades of colored tourmalines have been assigned specific names in the gemstone world. Bi-colored and multi-colored tourmalines have several names for the common combinations of colors. Crystals with red or pink cores and green borders are called watermelon-tourmalines. Stones with colorless crystals and black tips are called Maur's Head or Moor's Head, while colorless crystals with red tips are called Turk's Head. If the color zones are arranged one on top of the other, the stone is considered a rainbow tourmaline.

The red variety of tourmaline changes its name based on the coloring in different types of lighting. Deep red tourmaline named rubellite shows the same fine ruby-red shade in daylight and in artificial light. Should the color change when the source of light changes, the stone is simply called a pink tourmaline. With its exquisitely intense coloring, rubellite was once the victim of misidentification for rubies in the Russian crown jewels.

Green tourmalines come in a variety of shades, including leek-green, intense yellow-green, olive-green and brownish-green. Chromium-tourmaline is the trade name for the emerald-green variety. Its beautiful color is strikingly similar to the fine color of emeralds. Blue-green and dark bottle-green are the most rare and highly coveted green hues.

Perhaps the most beautiful variety is the Paraiba tourmaline. It ranges in color from electric blue to neon blue-green to sizzling turquoise. Discovered in the Brazilian state of Paraiba, its vivid color has not been consistently seen in any other gemstone variety. Its spectacular color is due to the presence of a small amount of copper. A study by the German Foundation for Gemstone Research also discovered a surprisingly high content of gold in the stones.

Until recently, there was one striking gap in the range of colors displayed by tourmaline. Pure yellow shades were missing and most of the yellow tourmalines that were found showed a slightly brownish tinge. In the year 2000, however, electric yellow tourmalines were found in Malawi in East Africa. With a clear and pure color, they were deemed "canary tourmalines" and the formerly missing color of yellow was added in excellent quality to the unlimited range of tourmaline colors.

Larger yellow tourmalines rarely occur. Only 10 percent of all the mined yellow stones are gem-quality and when cut, more than 95 percent of the harvest will weigh less than 1.00ct. Regardless of their smaller size, experienced cutters love working with the stones. Not only do they have brilliant color, yellow tourmalines are considered to be the only gemstones that have a fine scent. This is because in the place of their occurrence, tourmaline crystals are often embedded into black material that must be removed before the stones are cut. An owner of a Malawi gemstone mine discovered the black matter was easily removed when the rough crystals were boiled in water and lemon juice. Ever since then, yellow tourmalines from Malawi not only resemble fresh lemons in color, but also in their scent before they are cut.

Other tourmalines are called "indigolith" if they are blue and "dravite" if they are golden to dark brown. Black tourmalines are known as "schorls" and are mainly used for engraving. Although they were used as mourning jewelry, ancients believed black tourmalines to be stones that protected against negativity and strengthened the heart.

Tourmalines are piezoelectric, meaning they can generate electrical charges when heated, compressed or vibrated. They then become polarized crystalline magnets and can attract light objects. The Dutch knew about this effect and used heated tourmalines to extract ashes from their pipes. The stones were even favorite toys of Dutch children before their gem quality was established. Because the gem's electrical charges attract dust and small materials, some believe that wearing pink tourmalines will attract love and green ones will attract success.

Tourmaline has often been called the "muses' stone" because it is believed that its imaginative colors contain inspirational powers that grant enlightenment, enable creativity and express an artist's mood. Due to the stones' energetic conductivity and vast array of elements, they are thought to have powerful healing abilities and protect against many dangers. Tourmaline is supposed to be an especially powerful influence on love and friendship, fostering compassion and cool headedness. It is considered the traditional gift to give couples celebrating their 8th wedding anniversary.

Ever since the ancient days, the gem has been attributed with magical powers. Today, specific colors of tourmaline are thought to hold individualized powers. Black is believed to bring luck and happiness when rubbed. Green is said to encourage communication and bring success, while blue is a balancer that stimulates other tourmalines' effectiveness. Watermelon tourmaline is believed to increase perception and creativity, while balancing passivity and aggressiveness. Pink is thought to promote peace, increase spiritual understanding and bring forth love and friendship.

Aquamarine:
Aquamarine's name was derived from the Latin terms "aqua" meaning water and "mare" for sea. According to legend, aquamarine was the treasure of mermaids and held the power to keep sailors safe at sea. Sailors carried it to stay in the good graces of Poseidon and ward off seasickness. Other folklore says that aquamarine was the stone of the sea-goddesses and sirens. Sea goddesses were said to cleanse the stone in the ocean water at night by the light of the full moon. Beads of aquamarine are even found in ancient Egyptian mummy tombs, used as a tribute to the gods of the netherworld for safe passage.

From the lightest sky-blue to the deepest sea blue, aquamarines are found in an exceptionally beautiful spectrum of blue hues. With its clear brilliance, deeper colors are unusual in smaller sizes since it generally takes a larger stone to hold a darker shade. The most prized aquamarines are those displaying a deep, intense, pure blue with no green tints. These are more rare and therefore more valuable. Unlike its emerald sister, aquamarine is known for being relatively free of inclusions with evenly distributed color. It retains excellent clarity, which is why aquamarines are frequently cut with large step facets to show off their flawless surfaces, immaculate transparency and high brilliance.

The different shades of aquamarine are distinguished by their names. "Santa Maria" is the name for the rare, intensely deep blue aquamarines found in the Santa Maria de Itabira Mine in Brazil. Similar colors are found in some of the sparse aquamarine gemstone mines in Africa, especially in Mozambique. In order to better distinguish them, these aquamarines are denoted as "Santa Maria Africana." Not quite as deeply blue are "Espirito Santo" aquamarines from the Brazilian state of Espirito Santo. Another beautiful color has been named in honor of a Brazilian beauty queen from 1954, and has become famous as "Martha Rocha."

Aquamarine is thought to possess a number of mystical properties , with powers that allegedly develop best if the stone is immersed in sun-drenched water. It is a stone of peace, joy and happiness, especially in the renewing of relationships. Its pale blue color arises sympathy, trust and harmony, all feelings that soothe and calm emotional fires or problems. The gem is said to re-awaken love in married couples or spark new friendships. In fact, carrying an aquamarine is supposed to guarantee a happy marriage and to make its owner happy. As a necklace, it is the most magically ideal gift for a groom to give his bride on the day of their nuptials.

In ancient times, aquamarine was thought to be capable of preserving youth and health. In magic today, this beautiful stone is worn or carried to enhance the utilization of psychic powers. Aquamarine can be worn as a magic charm to ensure good health, to halt fear and to strengthen courage. Because it is a cleansing and purification stone, it can be worn or rubbed on the body as a part of a purification ritual. Aquamarine can also be worn or carried as a protective amulet while sailing or flying over water. Fishermen, sailors and pilots have long made it their special amulet against danger. Other modern beliefs suggest the Santa Maria aquamarine makes the heart beat faster.

Now and then, sensationally large crystals are found. The largest known aquamarine is a 243-pound stone found in Brazil in 1920. It was cut into many smaller stones, and a 13-pound uncut piece resides in the American Museum of Natural History. Another noted aquamarine is an 879.50ct step-cut flawless sea green stone that is on display in the British Museum of Natural History. Aquamarine is found in many exotic places around the world, including Afghanistan, Angola, Kenya, Madagascar, Mozambique, Nigeria, Pakistan, Sri Lanka, Russia, Zambia and Zimbabwe. Most of the gemstones available in the market today, however, come from Brazil.

Many modern designers have named aquamarine as their favorite stone, as its light color allows for a special creative freedom to bring out the character and brilliance of each stone. Gemstone artists get their inspiration for new cuts more often from aquamarines than from any other stone. These creative designer cuts have no doubt contributed to its high popularity. Aquamarine is the March birthstone and has become the traditional gift for 16 th and 19 th anniversary gifts. With an 8.0 ranking on the Mohs Scale , the stone is very durable and can stand up to everyday wear. It is the symbol for youth, hope, health and fidelity.

Tanzanite
No other gemstone discovery has made a bigger impact on the jewelry market than the recent newcomer, tanzanite. Its luscious color, and the fact that the stone is found in only one location throughout the world, makes tanzanite an exceptionally rare, valuable and highly sought-after gem.

Tanzanite’s mesmerizing saturation of color is what has made the stone so popular. It is the blue variety of the mineral zoisite and occurs in a beautiful range of colors. Rarely pure blue, the gem almost always displays signature overtones of purple. In smaller sizes, it tends toward light tones such as lavender, while in larger sizes, the gem typically displays deeper, richer blues and purples. The finest quality tanzanite is usually deep blue or violet, which is extremely spectacular in sizes above ten carats.

Tanzanite is pleochroic, meaning it shows the appearance of several colors in the same stone, depending on perspective. From different angles, the gem can appear blue, purple, yellow, grey or brown. Most rough crystals show a large proportion of brown shades, since tanzanite in its natural form is typically brown with red, orange, yellow or bronze hues.

Gem cutters may change this coloring by heating the stone to 500°C. This heat treatment releases the intense violet-blue colors for which the stone is famous. According to legend, the effect of heat on tanzanite was first discovered when brown zoisite crystals were caught on fire by a lightning strike. Local cattle herders noticed the beautiful blue crystals sparkling in the sun and picked them up, becoming the first tanzanite collectors.

The gem was first discovered near the base of Mount Kilimanjaro in the Merelani Hills of east-African Tanzania in 1967. This breathtaking location is the only known mining site on Earth for tanzanite. Right after its discovery, New York jeweler Louis Comfort Tiffany was presented with the first stones. Knowing it was going to be a sensation, he recommended finding a new name for the gem, since the gemological denomination “blue zoisite” reminded him of the word “suicide.” Tiffany suggested the name tanzanite, derived from its place of occurrence, and the new name quickly became established on the market. Tiffany & Co introduced the stone to the public in a spectacular promotional campaign two years after it had been discovered. It was enthusiastically celebrated as the “Gemstone of the 20th Century.”

A noted 122.70ct faceted tanzanite dubbed the “Midnight Blue” is on display at the Smithsonian Institution in Washington, D.C. In 1996, a 255.00ct tanzanite crystal was discovered near Arusha, but because of its many inclusions, it proved to be of little market value. Tanzanite ranks a hardness of 6.5-7.0 on the Mohs Scale and has become the traditional gift for couples celebrating their 24th anniversaries.

High-quality and larger-size tanzanites can be sold at extremely premium prices. Although demand for this beautiful gem continues to grow, supply shortages in recent years have hampered production and caused price fluctuations. In 1998, the weather phenomenon known as “El Nino” soaked Tanzania with heavy rains during what should have been the drought period. When the monsoons hit, the groundwater swells were high and caused devastating floods. Mines caved in and all hopes of finding additional tanzanite rough were swept away.

Because it is such a new gemstone, there is little folklore, superstitions or healing properties surrounding tanzanite. Some believe the stone helps people to be more practical, realistic and honest. It is thought to uplift and open the heart while helping one cope with change.
