OPALS

Opal is the most visually complex of all gemstones — a stone that contains the colours of every other gem within itself. Its extraordinary play-of-colour, caused by the diffraction of light through microscopic silica spheres, produces shifting spectral fireworks unlike anything else in the natural world. From the blazing reds and oranges of Mexican fire opal to the dark, mysterious depths of Australian black opal, each stone is a unique universe of light.
