Amethyst is an extremely sought-after gem which has been valued by many civilizations since antiquity. A variety of vitreous quartz, amethyst often forms dramatic prismatic crystals which are often formed into jewelry without being cut. Brazil and Uruguay are common sources of high quality amethyst. In the early Christian church, amethyst was believed to guard against intoxication, hence its derivation from the Greek "amethustos," meaning "not drunk."
Deep red garnet is derived from a number of minerals, including pyrope and almandine. Popularized in Bohemia in the Czech Republic, garnet has been used in decoration and jewelry across Europe for many years. Its color is generally a dark burgundy, sometimes with a hint of orange, pink, or purple.
