Highly-coveted boulder opal is second in rarity among opals only to the elusive black opal, and this highly reflective Koroit nut boulder opal mined in the Koroit opal field in Queensland, Australia is a AAA example. The rich brown ironstone matrix is so densely shot through with veins of opal in shades of electric green, blue, purple, and orange that it appears infused with glitter. An overall mesmerizing piece that will add dimension to any collection.

Dimensions: 3/4"L x 3/8"W x 1-3/4"H, Weight: 79 ct
