This stunning 23.66-gram Natural Koroit Boulder Opal comes from the famous Koroit Opal Field in Queensland, Australia, one of the most highly respected and sought-after sources of Boulder Opal in the world.
Measuring 0.80” long x 0.80” wide, this beautiful solid opal displays vibrant natural color flashes embedded within its ironstone host rock. Koroit Opals are especially prized for their distinctive patterns, rich contrast, and exceptional natural beauty formed over millions of years.
Unlike assembled opals, this is a 100% natural solid Boulder Opal, meaning the opal formed naturally within the ironstone matrix. This makes it far more durable, stable, and valuable than doublets or triplets.
Each Koroit Opal is completely unique, no two are ever alike.
