Black Round Coin - 6mm - Gilson Opals

Our round coins are flat and polished on both sides and around the edges, and are about 1mm thick. These 6mm round coins are perfect for creating accents that really catch the eye and make a statement. These flat, round, disc-shaped stones provide plenty of surface area for the fire of the opal to really light up. Like all of our black opals, these stones have an opaque black base with brilliant flashes of predominantly red fire and more subtle flashes of green and blue fire.
