Value
Up until the 18th century, amethyst was included in the cardinal, or most valuable, gemstones (along with diamond, sapphire, ruby, and emerald). However, since the discovery of extensive deposits in locations such as Brazil, it has lost most of its value.
Collectors look for depth of color, possibly with red flashes if cut conventionally.
The highest grade amethyst (called "Deep Russian") is exceptionally rare and therefore, when one is found, its value is dependent on the demand of collectors. It is, however, still orders of magnitude lower than the highest grade sapphires or rubies (padparadscha sapphire or "pigeon's blood" ruby).

Famous quotes containing the word value:
“And those handmade presents that children often bring home from school: They have so much value! The value is that the child put whatever he or she could into making them. The way we parents respond to the giving of such gifts is very important. To the child the gift is really self, and they want so much for their selves to be acceptable, to be loved.”
—Fred Rogers (20th century)
