Opal white 3mm round coin

Compatible with COE 33 / borosilicate glass

Our 3mm coin opals are are flat & polished on both sides and flat & polished along the edges. These stones are perfect for those tiny spaces--iris of the eye, headlight of a car, planet off in the distance... You name it, these great little stones will fit the bill.
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.
