Carnelian is orange chalcedony, a cryptocrystalline form of silica (quartz/moganite). Iron oxide provides its coloring, which ranges from pinkish orange to deep rusty red. It is said to boost courage and self confidence. In any case, they are pretty to look at!
These heart-shaped polished Carnelian pieces are approx. 1.5" across the lobes.
Note: price is for one heart. Photos show several to indicate the range of color and size variation of the current stock.
