Sculpted by natural banding and careful polish, this black onyx freeform highlights the quiet drama of contrast. Deep charcoal and black bands arc across the surface, giving way to a pale, crystalline interior—an exposed record of mineral growth layered over time.
Cut into a smooth, upright freeform, this piece balances organic movement with a stable, display-ready base. It works equally well as a focal point on a shelf or desk, or as part of a curated cabinet of geological specimens.
This is a one-of-a-kind stone. The exact piece shown is the one you will receive.
