This piece is a Light Boulder Opal set in Sterling Silver. This Milky Boulder Opal has a broad fire pattern which makes it even more appealing to the eye. This Opal displays strong flashes of red, blue, and green. Along the edge of the Boulder Opal you can see accents of Ironstone, the rock that Boulder Opal naturally forms in. This particular Opal comes from an Opal mine in the centre of Queensland, near Quilpie.
