Two of the stones I’ve seen at the Senckenberg Museum . One of them is amethyst, do you know what’s the other one?
Amethyst is a violet variety of quartz. The name comes from the ancient Greek “amethystos”, which means “not drunken”, a reference to the belief that the stone protected its owner from drunkenness.
The ancient Greeks wore amethyst and made drinking vessels decorated with it in the belief that it would prevent intoxication. It is one of several forms of quartz. Amethyst is a semiprecious stone.
