These 6mm spheres are big, beautiful, and perfectly polished with a high-gloss finish and lots of minty green fire that really pops in glass. Like all of our mint opals, they have an opaque white base with bright flashes of intense green fire and occasional subtle hints of blue and yellow. Once encased in glass, these stones look huge and will catch every eye in the room.
