Lot of 4 natural black opals from Ethiopia. 21.15 carats. Cabochons- 4.23 g - (4)

Black opals from Ethiopia are highly prized for their vibrant play-of-color, often displaying brightness and vivid patterns against a dark body tone. Ethiopian opal cabochons are smooth, rounded gemstones cut to accentuate their unique optical effects, making them ideal for fine jewelry. Originating from relatively recent discoveries in Ethiopia, these opals have gained popularity as alternatives to Australian black opals and often feature spectacular flashes of color ranging from blues to reds. A lot totaling 21.15 carats represents a meaningful collection, suitable for collectors or jewelers looking to incorporate exotic, high-quality opals into their designs.
