Sparkling Opal gem 22.85 (ct) Black Opal Top Quality Rough - Height: 32 mm - Width: 19 mm- 4.57 g - (1)

Black opals are among the most prized and spectacular varieties of opal gemstones, renowned for their vibrant play-of-color against a dark body tone. This 22.85-carat specimen is a rough gemstone, representing opal still in its natural, uncut state. The rough opal's substantial size with dimensions measuring 32 mm by 19 mm makes it a remarkable piece for gem cutters and collectors. Opals form from a solution of silicon dioxide and water, and the black opal's dark background enhances the gemstone's ability to diffract light, creating vivid flashes of color known as 'fire.' Originating mainly from Australia, black opals are treasured for their rarity and dazzling appearance. This specimen's quality and weight make it suitable both for collectors seeking natural mineral specimens and for artisans aspiring to craft exceptional jewelry pieces that showcase the stone's intense, natural beauty.
