Pendant Ethiopian Opal / cabochon / new Set in 925. Sterling silver Weight: 1.98 g (weighed without leather cord) 17.0 mm x 9.4 mm x 6.2 mm New and unworn Includes leather cord Opals from Australia have long been known. In recent years, however, a new variety from Ethiopia has been stealing a little 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 discovery is not known. Some sources date the introduction of the Welo opal to the Nairobi market in 1993. The discoverer is considered to be chemist Tilahun Yohannes and as early as 1994 geologist Dr. N. Barot reported in an article in the ICA Gazette about this gemstone novelty. Mining began slowly; in 1997 only 10 kilos were mined. The gemstone cutting workshop Eyaopal from Addis Ababa cut out 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 showed 350 cut opals at the Tucson trade fair. In 2008 commercial mining began. A new star among opals was born. Shipping as insured letter
