This beautifully cut Koroit Opal from Queensland, Australia features curvilinear lines and is dotted with light blue opal throughout. These 1-inch-thick polished blocks are made with a special casting method that makes them super clear, deep, and realistic. The print is made with an artisan Giclee process and has been enlarged for a great viewing experience. It’s a stunning piece that would make a great addition to any shelf, desk, or table.
