Amethyst is a quartz (silica) ranging from purple to dark purple. Its color is due to iron.
When heated to 400 ° C, its color changes and turns to yellow. This is why ametrine is found, a both violet and yellow stone.

The word comes from the ancient Greek A-Methoustos which is the negation of “being drunk”. The Greeks thought that its color was close to that of red wine cut with water.
The Romans drank their wine in amethyst cups to avoid drunkenness.
Today, it is considered the religious stone par excellence, which is why it could be observed on the rings of Catholic bishops until the beginning of the 21st century.
