Cantera Opal (Sold by the Pound)

Cantera Opal is a striking variety of Mexican opal that forms within volcanic rhyolite, creating a natural contrast between vibrant opal and its host rock. Mined primarily in Mexico, this opal often displays brilliant reds, oranges, greens, blues, and purples, either as solid seams or glowing pockets within the matrix. The word cantera refers to the quarry stone in which the opal is found. Highly prized for cabochons, carvings, and inlay work, Cantera Opal offers a bold, earthy aesthetic with each piece uniquely shaped by nature. Cantera opal sold by the pound will be random pull.
