We did it - 9mm spheres! These rainbow spheres are stunning, perfectly polished with a high gloss finish and bright red and pink fire that really pops. Like all of our rainbow opals, they have an transparent base with brilliant flashes of red, yellow, and pink fire and subtler hints of blue and green. These babies are big and bold---a great focal point for any piece.
