Doublet Opal

Opal is a fantastic stone that comes in beautiful color patterns. Doublet opals do not comprise natural gemstones while they manifest several stone layers glued together. It is for this reason that they look like black opal. A doublet opal consists of several flakes of stone fixed together. The backing is meant to give it a better appearance.
