Unique Crystal Opal Rough 46 Carats, Ethiopian Opal Raw Rough - Height: 39 cm - Width: 26 cm- 9.2 g - (1)

Crystal opal is a transparent to semi-transparent variety of opal prized for its play of color and clarity. This unique rough crystal opal, weighing 46 carats, originates from Ethiopia, a region known for its vibrant opal deposits. Rough opal displays a natural raw form that can show flashes of iridescence under light due to silica sphere diffraction within its structure. Ethiopian opals are notable for their hydrophane properties, which means they can absorb water and change appearance temporarily. Collectors and lapidaries value rough opal both for its beauty and as material to cut and polish into gemstones. Such raw specimens offer a direct connection to the geological processes that create opal’s characteristic color play and are appreciated for their natural, unaltered state.
