| Frequently Asked Questions (FAQ) / Opal Doublet |
What is the difference between an opal doublet and a normal opal? An opal doublet is a slice of precious opal glued to a black backing. This technique is used frequently with rare opal to produce larger and stronger pieces at a lower cost. The black backing, usually made of vitriolite or common opal, also causes the color of the opal to become darker and more vibrant. |
