Boulder Opal Jewelry
Most boulder opal is mined in Australia where thin veins of opal form within the brown ironstone matrix, creating a wonderfully unique picture stone. The jewelry pieces featured here include stones from several different mines, all with unique attributes which create different types of opal and boulder opal stones. These mines include Koroit, Yowah, Jundah, Opalton and more. The stones are set in sterling silver designed and created by Native American artisans.
