“This is a rough sample of natural unheated RED carnelian. The dark parts are actually pure cherry red. On the photo they look more brownish, than they actually are. It is the best and most intense red color of a natural carnelian, which i ever saw.
The specimen has a colorless very transparent core, which lets the light go deep into the specimen and causes in this way the dramatic glowing effect.”
