White 10mm Round Coin opals

Our round coins are flat and polished on both sides and around the edges, and are about 1mm thick. These 10mm round coins are perfect for creating bold, flashy accents that really make a statement. The flat, round, disc shape provides plenty of surface area for the fire of the opal to really light up. Each stone flashes a rainbow of intense fire.
Like all of our white opals, they have an opaque white base with brilliant flashes of red, yellow, and pink fire and subtler hints of blue and green. The base color of white opals can vary from fairly opaque to solid white. If you prefer a semi-transparent or a more opaque base, please let us know in the customer comments during the checkout process and we will do our best to fill your request.
