This is the birthstone for the month of February. This fine stone (sometimes referred to as semi precious) is undoubtedly the most popular quartz. Amethyst, which once competed with the finest gemstones, became affordable in the early 19th century when significant deposits were discovered in Brazil. Variety: Quartz Purple
