Lot of 2 natural Ethiopian black opals. 3.44 carats. No reserve! Cabochons- 0.69 g - (2)

Ethiopian black opals are cherished for their vibrant play-of-color set against a dark body tone, making them a striking variety of opal. These natural gemstones, often forming as cabochons, safely showcase a mesmerizing array of colors including blues, greens, and fiery reds. With a combined weight of 3.44 carats, this pair exemplifies the unique allure of Ethiopian black opals, known for their origin in the Wollo Province of Ethiopia. These opals form in volcanic rock, where silica gel fills cracks and cavities, eventually solidifying into these colorful gems. Collectors and jewelers prize such stones due to their rarity and the intensity of their color patterns. The cabochon cut, a smooth rounded shape without facets, best enhances the play-of-color characteristic, making these opals exceptional for decorative or jewelry use.
