Sterling silver amethyst jewelry is the accessory that is gaining the dignity of the royal one. This is primarily because of the dark purple color of the amethyst gemstone that gives a rich appearance. And when it is embedded in the silver setting to create a genuine amethyst ring, it gets to a different level altogether. Amethyst is a gemstone that comes in many purple shades, ranging from light purple, violet purple, reddish-purple, and deep purple.
