Amethyst is ideal for any type of jewelry design because it is considered both hard and durable. Amethyst stones are typically worn as pendants, necklaces, earrings, and especially for amethyst rings. Due to amethyst having a purple-violet color, many believe that amethyst should be worn by females only. However, purple is the color of royalty and royalty has no gender preference. Therefore, it is an excellent choice of stone for men or women. Amethyst is harder than most other materials, so it is very resistant to wear and tear. Amethyst is a favorite for many jewelers because of the large sizes and shapes available. Amethyst is the most popular purple-violet colored gemstone on the market today, followed by blue-violet tanzanite, spinel, sapphire and iolite.
