Highly-coveted boulder opal is second in rarity among opals only to the elusive black opal, and this shimmering over 40-gram Koroit nut boulder opal mined in the Koroit opal field in Queensland, Australia is a AAA example. The rich brown ironstone matrix is shot through with veins of opal in shades of electric purple, green, and yellow. An overall mesmerizing piece that will add dimension to any collection.

Dimensions: 1"L x 3/4"W x 2"H, Weight: 217.5 ct
