Cairngorm
from the Antique Jewelry University
Cairngorm is the name given to a citrine quartz variety with an amber or brown color mined in the Cairngorm mountains, Scotland until the source was exhausted. Cairngorms were used in traditional Scottish jewelry of the 19th century and were often accompanied by amethyst. It is not unusual to find thistle shapes in Scottish jewelry carved from these stones. Cairngorms are often imitated with glass in Scottish jewelry.
