These 5mm spheres are big, bright and perfectly polished with a high-gloss finish and multi-color, green-dominant fire that really pops. Like all of our RGB opals, they have an opaque black base with brilliant flashes of green fire and flecks of red, yellow, and blue. Once encased in glass, these 5mm spheres look huge. Works as a great focal point on even the biggest piece.
RGB opals flash predominantly green fire, whereas our black opals flash predominantly red fire.
Did you know our Gilson Created Opal does not decompose, off gas or release any substances when heated to very high temperatures? Read more about our testing
