We currently have a stunning range of Premium Boulder Opals in stock – each one brilliant and one of a kind. They are notably higher in price than our previous selections of Boulder Opals, so what is it that gives a Boulder Opal its value?
Boulder Opals are easily distinguished by their layer of solid brown ironstone left on the back of the stone. Boulder Opals are mined from large ironstone boulders under the ground. Thin veins of colourful opal forms in the cracks and fissures in these boulders which are cut into the stones we sell.
