Opal white 4mm round

Compatible with COE 33 / borosilicate glass

Our white 4mm round opals are flat on one side and rounded on the other. They are opaque with a white base and flash bright fire with predominantly red tones, but also hints of green, pink, yellow, and blue. These are stunning stones with a great polish. The pictures don't do them justice. They are great as eyes, focal points, planets, you name it! They work great in glass, and a pair of our 4mm opals set in silver or white gold would also make great earring set.
