Drawing it's interesting patterns from stalagmites, this unique and nicely domed Kokoweef Cave Onyx cabochon has a "flowering" pattern in bands of tans and creams. This would make a truly incredible piece of jewelry or would make a fine addition for any collector.

I cut this cab by hand and it's been polished to a high polish both front and back with slightly rounded bottom edges for easy setting.
Kokoweef Cave Onyx, also known as “cave popcorn”, is a stalactite found in the Kokoweef cavern in Southern California.
This material consists mainly of calcite and aragonite, and the formations started to grow as far back as the Jurassic Period (155 mya). There’s also a hidden surprise to this material: if you hold a piece under a UV light, you will see it glow a fluorescent green.
