These 8mm spheres are spectacular. They are big and flashy, perfectly polished with a high-gloss finish ready to be set in glass. Like all of our green opals, they have an opaque black base with brilliant flashes of deep green fire and occasional subtle hints of blue. 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.
