Description from the seller
A Rare Matched Pair of Natural Ethiopian Black Opals — Where Fire Meets Darkness
This extraordinary matched pair of natural Ethiopian Welo Black Opals presents a breathtaking spectacle of colour that is rarely found in a single stone, let alone two. Together they weigh a remarkable 13.90 carats, making this an exceptional collector's acquisition or the centrepiece of a truly unique jewellery creation.
The Oval — 7.45 ct | 17.6 x 11.4 x 7.9 mm
Against a deep, velvety black body tone, the oval cabochon erupts with a bold and dramatic play of colour. Vivid crimson reds and deep magentas dominate the centre, surrounded by electric blues, rich greens and flashes of violet — a colour palette that evokes the intensity of a volcanic landscape at night. The smooth, highly polished dome captures and refracts light from every angle, igniting the fire within with extraordinary brilliance.
The Pear — 6.45 ct | 15 x 14.1 x 7.8 mm
The pear cabochon offers a strikingly different yet perfectly complementary character. Vivid electric greens take centre stage, accompanied by fiery oranges, golden yellows and deep reds that flash and shift with every movement. The colour play has an almost three-dimensional quality — as if the fire is alive, breathing and dancing beneath the surface of the stone.
Together as a Pair
Side by side, these two stones create a visual dialogue between two expressions of the same natural wonder — one warm and volcanic, the other electric and luminous. Whether set as a pair of earrings, a statement ring duo or kept as collector pieces, they are a remarkable testament to the extraordinary natural beauty of Ethiopian opals.

About Ethiopian Welo Black Opals
Ethiopian Welo opals are widely regarded as among the most spectacular opals in the world. Sourced from the Welo province of Ethiopia, these hydrophane opals are celebrated for their extraordinary play of colour, deep body tone and exceptional brightness. The smoking treatment — a traditional and widely accepted enhancement method — deepens the natural body tone to produce the rich black background that makes the colour play appear so dramatically vivid.
Please Note:
• Natural characteristics including internal formations and inclusions are clearly visible in listing photos and are a natural property of genuine opals
• Colour appearance may vary slightly depending on lighting conditions and screen settings
• Stone is unset and sold loose
• In some photos, backlighting has been used to better showcase the colour play
