This very cool cabochon was cut from either stalactites or stalagmites found in caverns near Kokoweef Peak in California. Kokoweef Cave Onyx is a calcium carbonate accretion from these caverns. Legend has it that in the 1920s, a man discovered an underground river full of golden nuggets in these limestone caverns (people are still searching for this river). Even though there's no gold in this cabochon, I decided to keep it since it's the first one I cut. More to come later for the rest of you!

Dimensions: 44mm x 25mm x 6mm.  Weight: 52.75 carats.

This cabochon is in my personal collection; it is not available for sale.
