The Opal Outlet Shop provides boulder opal, including this Boulder Rough Opal 105.
Boulder opal is mined with its host ironstone or sandstone still attached. This material actually reinforces the opal, which tends to be very thin. The host backing also has the advantage of darkening the background and increasing the opal’s play of color.
