Amethyst – February’s Birthstone

Faceted Amethyst Necklace - Barbary Coast Collection

Featuring faceted Amethyst, Purple Freshwater Pearls, Cranberry Freshwater Pearls, Rose Quartz, and accented by Vermeil beads, I recently added this necklace to the Barbary Coast Collection.

Amethyst was used as a gemstone by the ancient Egyptians and was largely employed in antiquity for intaglios (cameos). Beads of Amethyst are found in Anglo-Saxon graves in England. It is a widely distributed mineral, but fine, clear specimens that are suitable for cutting as ornamental stones are confined to comparatively few localities. Such crystals occur either in the cavities of mineral-veins and in granitic rocks, or as a lining in agate geodes. A huge geode, or “Amethyst-grotto”, from near Santa Cruz in southern Brazil was exhibited at the Düsseldorf Exhibition of 1902. Many of the hollow agates of Brazil and Uruguay contain a crop of Amethyst crystals in the interior. Much fine Amethyst comes from Russia, especially from near Mursinka in the Ekaterinburg district, where it occurs in drusy cavities in granitic rocks. Many localities in India yield Amethyst; and it is found also in Sri Lanka, chiefly as pebbles.

Usually Purple to Lavender, several descriptive terms have been coined in the gem trade to describe the varying colors of Amethyst. “Rose de France” is usually a pale pinkish lavender or lilac shade (usually the least sought color). The most prized color is an intense violet with red flashes and is called “Siberian”, although gems of this color may occur from several locations other than Siberia, notably Uruguay and Zambia. In more recent times, certain gems (usually of Bolivian origin) that have shown alternate bands of Amethyst purple with Citrine orange have been given the name Ametrine. Purple Corundum, or Sapphire of Amethystine tint, is called Oriental Amethyst, but this expression is often applied by jewelers to fine examples of the ordinary Amethystine quartz, even when not derived from eastern sources. Professional gemological associations, such as the Gemological Institute of America (GIA) or the American Gemological Society (AGS), discourage the use of the term “Oriental Amethyst” to describe any gem, as it may be misleading.

Spring Colors for the Barbary Coast Collection

Tropical Garden Necklace - Amethyst, Jade, Freshwater Pearls, Amber

These are a few of the color combinations I am currently working on for my Spring 2007 additions to the Barbary Coast Collection.

The first necklace features Peridot nuggets, Champagne Quartz, Yellow and Lavender Jade, various colored Freshwater Pearls, Amber, and Ametrine nuggets accented with Vermeil beads. Ametrine, also known as trystine or by its trade name as bolivianite, is a naturally occurring variety of quartz. It is a mixture of Amethyst and Citrine with zones of purple and yellow or orange. Almost all commercially available Ametrine is mined in Bolivia, although there are deposits being exploited in Brazil and India. The color of the zones visible within Ametrine are due to differing oxidation states of iron within the crystal. The different oxidation states occur due to there being a temperature gradient across the crystal during its formation.

The second necklace features rare hand-carved Onyx, Freshwater Pearls, Lava, Stick Pearls, Faceted CZ Tear Drop beads, and is accented with Fine Silver Bali beads.
