Natural South Australian Boulder Opal (loose gemstone)

A loose gemstone purchased from an Adelaide jeweller and gemstone dealer in 2010. It has been polished and is ready to be set into a ring or pendant. Unique item, best viewed up close. Australian Boulder opals are the second most valuable type of opal. They are distinguished by their layer of solid brown ironstone left on the back of the stone. As the name suggests, boulder opals are mined from large ironstone boulders under the ground.
