Amethyst is believed to be a bearer of mystical powers. Amethyst is extremely solid and obtains a 7 rating on Mohs Scale. They were named for a character in Greek mythology named Amethystos, and have a long history of getting associated with royalty and riches. For amethyst rings the darker colors are prized higher and considered more valuable, especially Siberian amethyst, which incidently is not necessarily from Siberia. Go to your trusted jeweler and ask whether the stone is an imitation or the real deal. Massive or tiny, silver or gold, and more, there is simply no general shortage of the selection of ring kinds available. The deepest violet shade is the most expensive and prices go lower as the color range goes lighter. They have an air of innocence and purity.
