What is Amethyst Gemstone?
Amethyst is the rarest form of quartz and possibly the most popular form of quartz in the world. It’s a fairly hard gem, has six sides, and can be found within geodes all across the globe. Amethyst is usually available in crystal form or a mass. Nutritional analysis shows that some amethyst crystals contain naturally-occurring manganese. Many stones on the market are not natural; they are often heat treated to produce a darker shade of purple.
