Boulder Opal Loose

Boulder opal is an absolutely magnificent gemstone. Arguably the rarest and most valuable of all Opal gems boulder opal is a diminishing resource (which means it is genuinely running out). Each opal is unique, each gemstone is hand-carved from 'veins' of opal colour that ebb and flow through the heart of the ironstone. If you are looking for a genuinely rare form of opal that is incredibly unique, then boulder opal is the one!
