Carnelian - knowledge base, jewelry
Properties of carnelian physiological effects, zodiac signs and carnelian jewelry.
Carnelian is an orange-red and mostly translucent variety of chalcedony.
The different shades of colour are caused by iron oxide.
Staining can be used to hide or at least fade the streaking.
The name carnelian is presumably derived from the Latin word for cherry, based on its colour. Most carnelian sold today is actually a dyed and then heat-treated agate. Natural carnelian can be identified by the fact that it shows a cloudy colour distribution when translucent, whereas painted agate shows bands. Carnelian was one of the most precious stones in ancient times, and the ancient Greeks considered it a symbol of the returning sun because of its colour.
