A pineapple opal is a unique type of opal formation that resembles the shape of a pineapple. These specimens are typically found in Australia and are characterized by their intricate, spiky surface structure, which is the result of opal replacing a mineral called glauberite. The combination of the opal's vibrant colors and the unusual shape makes pineapple opals particularly prized by collectors.
