2 Ethiopian Opal stud earrings / cabochon / new Set in 925 sterling silver Total weight: 1.24 g / 6.2 ct 8.9 mm x 4.9 mm x 16.0 mm New and unworn Opals from Australia have been known for a long time. In recent years, however, a new variety from Ethiopia has been stealing some of the spotlight: the Welo opal! This stone is translucent and captivates with its characteristic, unique light reflections. It was discovered in the Semien Wollo mountain region in northeastern Ethiopia. The exact time of the find is not known. Some sources date the introduction of Welo opals on the Nairobi market to 1993. The discoverer is regarded as the chemist Tilahun Yohannes, and as early as 1994 the geologist Dr. N. Barot reported in an article in the ICA Gazette about this gemstone novelty. Mining started slowly; in 1997 only 10 kilograms were mined. The jewelry maker Eyaopal from Addis Ababa cut 400 grams from it. In the same year, the Welo opal was presented at the international mineral fair in Sainte-Marie, and a year later Eyaopal displayed 350 cut opals at the Tucson trade fair. Commercial mining began in 2008. A new star among opals had been born. Shipping as insured registered mail
