Welo Opal, 3.16 cts. 12.4 × 9.1 mm, Coffin

A 3.16ct natural Welo opal from Ethiopia, faceted in a coffin cut. Near-colorless body with strong play-of-color — broad flashes of green, teal, and pink shift across the table as the stone moves. The step-cut beveled edges give it a clean, architectural feel that lets the fire speak for itself.

Welo opals are hydrophane, meaning that they have a very porous structure and can absorb water and other liquids, which makes them unsuitable for everyday jewelry wear. This is a collector's stone — best appreciated as a specimen or display piece.
