CARNELIAN TUMBLED STONES

Carnelian is the red, orange, or amber variety of Chalcedony. Though often a solid color, it may also be banded, in which case it would be jointly classified as both Agate and Carnelian. Carnelian is an ancient gemstone, having been used as a gem material since antiquity. Although still used as a gemstone today, its significance and value have been diminished since ancient times.

Carnelian differs from Jasper in that Jasper will always be opaque, whereas Carnelian is translucent. Carnelian may be nearly opaque but will still let light through when viewed from the edges.
