These 6mm black spheres are stunning. They are perfectly polished with a high-gloss finish and a solid black base color with brilliant multi-color flashes of red, green, and blue fire (predominantly red). Once encased in glass these opals look HUGE and will catch every eye in the room. Works great as a focal point on even the biggest piece.
Did you know our Gilson Created Opal does not decompose, off gas or
release any substances when heated to very high temperatures? Read more
