Reveal smoldering depth with our Black Ember Nebula Opal™ Rough Block. Set against a true black base, this striking Lab-Crafted™ imitation opal displays ember-red, orange, green, and gold fire flowing through the material like glowing coals beneath dark glass. The color play appears in organic veins and pockets rather than uniform sheets, creating a dramatic, high-contrast look prized by lapidaries. This resin-based imitation opal lapidary rough is engineered for cutting, carving, and inlay across jewelry and specialty craft applications.
