Amethyst is a form of quartz and is the most highly prized variety. The top grade is a deep purple in color and is free from flaws or inclusions. The ancient Greeks believed that the stone would protect them from the effects of drinking wine when held under the tongue while drinking. The ancient cultures believed that by wearing amethyst jewelry it would insure pleasant dreams, improve memory, and provide protection from poisoning. The gem was held in high esteem and it was even used in the foundation walls of New Jerusalem and in the breastplate of the High Priest of Israel. Catherine the Great had a true fondness for amethyst jewelry and her love for the gem helped in developing sources in Russia and contributed to the enrichment of the Russian Treasury. The British Crown Jewels are still adorned by some of these fine gems. Very large pieces were carved into decorative objects and used to make drinking goblets. This Russian variety was most often banded with white quartz giving it a very unique appearance.
 
The gem is very hard in composition and thus makes it very compatible in use with all types of sterling silver jewelry. It wears quite well in amethyst rings and amethyst bracelets because of its toughness and durability. One drawback of the stone is that it can fade in color if left in strong sunlight for a long duration. Amethyst jewelry still maintains a high degree of popularity in the United States and worldwide. Although not used nearly as frequently as turquoise, fine examples of this beautiful gem can frequently be found in the contemporary works of Native American jewelry.
