Rare Boulder Opal Silver Pendant from Australia - 0.6" - 1.44 Grams bracelet and still is minedThis is a fantastic and extremely rare Boulder Opal pendant from Australia in sterling silver. 2% of Australian opal is the second (after Black Opal) most prized form of opal, a unique form known as boulder opal. The opal usually forms as thin veins within these boulders, and most stones are cut to include some of the host ironstone matrix. Boulder opal is sometimes referred to as opal in matrix for this reason. Location: Western Queensland, Australia
