Lot of 2 natural Ethiopian black opals. 3.26 carats. No reserve! Cabochons- 0.65 g - (2)

Ethiopian black opals are among the rarest and most coveted varieties of opal, known for their intense play-of-color and unique body tones ranging from near-black to dark backgrounds which accentuate fiery color flashes. Opals are hydrated amorphous forms of silica, famed for their shifting iridescence caused by diffraction within microscopic silica spheres. Black opals, in particular, are prized because their dark base color provides a stark contrast that makes the colors more vivid and captivating. Boasting a combined weight of 3.26 carats from two cabochon-cut stones, this lot offers collectors pieces that display the characteristic beauty and rarity of Ethiopian black opals. The cabochon cut, featuring a smooth domed surface, is typical for opals to maximize the visual play-of-color and protect the stone from fracture. Ethiopian opals have gained popularity for their remarkable range of colors and more accessible prices compared to the classical Australian black opal. These stones are excellent choices for jewelry or collectors focusing on rare gemstones with intense visual appeal.
