AAA RGB Tumbled Opals

These AAA quality, tumbled RGB opals have an opaque black base & flash red, blue & (mostly) green. These stones flash in a way that is quite different from the other black opals, which is red dominant. Our AAA tumbled opals are made from the same top quality material as cabochons, but they are tumbled instead of cut. While each batch is different, you can expect 5 to 10 pieces per gram, with each piece being between 4mm and 8mm approximately. They are compatible with COE 33 / borosilicate glass. Sold by the gram.
