Opal & Concrete 9ct Gold Ring

Opal & Concrete 9ct Gold Ring


Opal set in ‘concrete’, on a smooth 9ct gold wire band.

Opal is hydrated silicon dioxide. It is amorphous, meaning it has no crystalline structure and no definite chemical composition and is therefore considered to be a “mineraloid” rather than a “mineral.” Over time, this gelatinous mix seeped deep into fractures, veins and between the layers of underground sedimentary rock, and the solidified material, Opal, formed as much of the water evaporated. Common Opal has a milky or pearly luster, known as “opalescence.”

‘Concrete’ made with an epoxy resin.
