Origin & sourcesLaboratory-grown, e.g. Gilson (France) and Kyocera (Japan).
CompositionLab-grown silica spheres (some contain resin), arranged like natural precious opal

How it forms

Silica spheres are settled and bonded in a lab to copy natural play-of-colour. Many show a 'lizard-skin' or chicken-wire pattern under magnification, which helps tell them from natural opal.
