An opal pineapple is a rare and unique formation of opal that resembles the shape of a pineapple. These formations occur when opal replaces the mineral gypsum or glauberite, resulting in a crystalline structure with a similar appearance to the segmented surface of a pineapple. Found primarily in White Cliffs, New South Wales, Australia, opal pineapples are highly prized by collectors for their unusual shape and vibrant colors.
