The "vermeil" technique of plating sterling silver with gold originated in France in the 1750s. It differs from "gold filled" or "gold plated" in terms of the thickness or thinness of the microns over sterling silver. "Gold filled" pieces have a much thicker layer, between 15 and 45 microns, which is mechanically bonded to the base metal with heat and pressure. Vermeil is a more expensive version of "gold plated". It does not wear off as quickly as gold plating does. However, over time, vermeil wears off and therefore will require re-plating.
Over time your plated items will need to be re-plated. Contact your local jeweler for information on plating services.
Pronounced SAV-OH-RITE, the tsavorite gemstone features an intense green color that ranges from a vivid light hue to a deep, velvety forest shade. It is a member of the garnet family and is often referred to as a green grossularite. Like other garnets, tsavorite is naturally pristine with no treatments and features a strikingly high brilliance.
In 1967, British geologist Campbell R. Brides discovered tsavorite in Tanzania. He found strange, potato-shaped rocks that had breathtakingly beautiful green grains and crystals inside them. In 1971, he discovered the same gemstone vein extended into Kenya, where he could officially start exploiting the occurrence.
Henry Platt, the former president of Tiffany & Co in New York, named the stone after its occurrence near the famous game frontier, Tsavo-National Park. In 1974, Tiffany’s started a special promotion campaign to make tsavorite well known throughout the United States. Campaigns in other countries followed, and tsavorite soon became sought-after everywhere.
Tsavorite is quite rare and can cost several thousand dollars per carat depending on size and quality. Larger stones are exceedingly scarce. Only occasionally is a rough crystal more than 5.00ct found, making tsavorites weighing 2.00ct or more quite valuable. Fortunately, the brilliance and luminosity of these gems are displayed even in smaller sizes. They rank a hardness of 7.5 on the Mohs Scale and enjoy an especially high light-refraction index.
Too new to have folklore of its own, tsavorite is believed to hold the mystical powers of garnet, including protection and healing. Garnets also symbolize loyalty and can be exchanged between friends to ensure they meet again.
Named by the Romans, who thought the gems were formed from moonlight, moonstones have a floating light effect called “adularescence.” They often have translucent grounds with silvery white or blue flashes. Moonstone almost seems magical with a ghostly, shimmering glow floating in a crystalline material. With a clarity range of transparent to translucent, the gem’s body color can range from colorless to gray, brown, yellow, orange, green or pink. The best moonstone has a blue sheen, perfect clarity and a colorless body color. One variety called “rainbow moonstone” has a sheen that features a variety of rainbow hues.
Moonstones are usually cut in smooth, domed cabochon shapes to maximize the effects of sheen and adularescence. Fine moonstone is already quite rare and becoming rarer. It is mined in Sri Lanka, India, Australia, Brazil, Canada and Kenya. Rainbow moonstone is also found in Madagascar.
Ancient Romans thought moonstones changed appearances with the phases of the moon. They also believed that an image of Diana, the goddess of the moon, could be seen in each stone. During the Middle Ages, people believed one could gaze into the gem, fall into a deep sleep, and see the future. Today the stone represents serenity, happiness and friendship. It is believed to be a stone of inner strength and is said to arouse passions. In Europe, moonstone is considered the birthstone for June, although in the United States, it shares that distinction with the pearl. It is traditionally given as a 13th wedding anniversary gift.
