Large Top Grade Flowering Tube Onyx Designer Cut Cabochon

This eye popping large cabochon of increasingly rare Flowering Tube Onyx has multiple fantastic bloom "flowering" on it in colorfully majestic and distinctly strong banding patterns of bright orange, tan, brown and black. This one-of-a-kind treasure would make a truly incredible piece of jewelry or would make a nice addition to any collection.

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.

Found in the Henry Mountains in Southern Utah, this highly coveted material is no longer being mined as the mine ran out years ago and is only rarely available through those who saved it in collections or for later sales. It is very common that this material is found with fractures and pitting, and also due to it's "softness", is therefore difficult to work with and cut.
