Australian Boulder Opal Pendant Wire Wrapped in Argentium Silver

Opal is a hydrated silica material with a hardness of 5.5 to 6.5. it is composed of submicroscopic silica spheres that are bonded together with water and additional silica. An Australian legend says that a gigantic opal governs the stars, human love, and the gold within the mines.

This is an Australian Boulder opal specimen, carved into a cabochon by my partner and wire wrapped in Argentium Silver by me. Australian Boulder opals are the second most valuable type of opal (following black opal), and it's hard to capture their beauty in a photo! Boulder opals are easily distinguished by their layer of solid brown ironstone left on the back of the stone. Boulder opals, as the name suggests, are mined from large ironstone boulders under the ground. Thin veins of colourful opal forms in cracks and fissures in these boulders.
