Additional Information
Carnelian is more of a term to descirbe a solid red (red-brown) - translucent agate. It is not from a particular locale, but rather the red color. It is usualy not banded, but can be. The word is derived from the Latin word meaning horn, in reference to the sometimes fleshy color.
