Fiery opal fragments combine into a single sparkling gemstone, forming Australian Mosaic Opal.
Borrowing from the ancient traditions of mosaic creation, Australian Mosaic Opal is a gemstone assembled from the individual fragments of fiery Australian opals. The finest pieces of opal that cannot be shaped into traditional gems are arranged against a dark field of material. The arrangement is agonized over so that the finished product will possess the expected opal play of color This is then capped with a layer of transparent resin or glass, both to protect the precious opal chips within and to allow more light to play across the shimmering surface of the opal gem composite. Once polished, the finished product can compare to the finest available specimens regarding color and fire.
