123cts Crystal Opal Specimen Rough- 24.69 g

Crystal opal is a translucent variety of opal that exhibits a clear to semi-transparent body with a delicate play of color that shifts with lighting and viewing angle. Rough crystal opal specimens like this one offer collectors a raw glimpse at the natural beauty before cutting and polishing reveal fully developed fire. Opals form from hydrated silica gel deposited in cracks or cavities of rocks, resulting in their signature iridescence caused by diffraction of light through silica spheres. This rough specimen can be appreciated both for its potential as a gemstone and as a mineralogical curiosity highlighting opal's unique formation processes. Crystal opals are especially prized for their clarity combined with colorful internal flashes, contrasting with the more opaque common opal.
