A form of translucent reddish-orange to red agate, also known as Mecca stone, Pigeon Blood Agate, Sardoine, Cornelian. The name is most commonly believed to be derived from the Latin carne, meaning flesh. It is sometimes referred to as Cornelian rather than Carnelian as others attribute the name to the Latin cor, meaning heart. Often Heat-treated. (It's been thrown in the fire for centuries to improve the reddish coloring).
