They are known for their unique play-of-color and high transparency, which makes them highly prized among jewelers and collectors. Most Welo opals are hydrophane, meaning they can absorb water. When they do, they can become more transparent and intensify their colors, but they are also more prone to cracking due to changes in humidity.\nCharacteristics of Welo Opals\nThese opals display a lively, rainbow-like play-of-color that changes with the viewing angle. This effect is caused by the diffraction of light on tiny silica spheres within the stone's structure. Their transparency ranges from clear to opaque, with clearer pieces emphasizing optical effects. The color range includes white, yellow, orange, red, green, blue, and violet tones. Their Mohs hardness is between 5.5 and 6.5, requiring careful handling to prevent damage.\nMining and Processing\nWelo opals are mainly mined in northern Ethiopia. The first discoveries date back to the 1990s, but global interest surged around 2008, when their quality and color range attracted worldwide attention. These opals quickly rivaled traditional Australian opals thanks to their vibrant hues. Once extracted, the stones are cut, shaped, and polished to bring out their natural beauty to the fullest.\nCare Instructions\nWelo opals are sensitive to temperature and humidity fluctuations, which can cause cracking or color fading. They must be protected from extreme conditions. For cleaning, only use a slightly damp cloth. Avoid chemicals or ultrasonic cleaners, which can damage the surface and internal structure. Store opals in a dry, safe place to avoid moisture or impacts.\nMarket and Value\nWelo opals quickly gained recognition for their affordability and extraordinary play-of-color. Prices vary based on quality, size, and transparency. The most exceptional stones, with vibrant color and high luster, often fetch premium prices on the international market among collectors and jewelers.\nPrecious Opal – Welo, Ethiopia\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028704497989,"sku":"OP222","price":30.03,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/41699_photoroom-015-20250403-114643.jpg?v=1779385104","url":"https:\/\/moldavite.it\/en\/products\/precious-opal-65ct-welo-ethiopia-op222","provider":"Moldavite.it","version":"1.0","type":"link"}
