Characteristics of the cabochon cut The cabochon cut is characterized by a smooth, domed upper surface without facets, while the bottom of the stone is flat or slightly concave. This shape allows light to diffuse across the curved surface from many angles, effectively enhancing the iridescent play of colors and uniformly distributing the opalescent effects throughout the stone. Stability and protection of the opal The rounded edges of the cabochon protect the opal from mechanical damage, which is particularly important given its relatively low hardness. In the case of hydrophane Ethiopian opals, this shape also offers a practical advantage: it reduces internal stress and decreases the risk of cracks during water absorption. Color variability of Ethiopian opals Ethiopian opal cabochons display a wide range of colors, from light milky white shades to yellow and orange hues, with vibrant red and green flashes. Some specimens also exhibit rare blue or purple plays of color, which flow harmoniously over the domed surface thanks to the cabochon cut.\u003c\/p\u003e","brand":"PeltramMinerals","offers":[{"title":"Default Title","offer_id":58028011618629,"sku":"OPK133","price":309.61,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0881\/1659\/2965\/files\/70645_20-pcs-precious-opal-cabochons---welo--ethiopia_b0cd1ddd-519c-49e7-b982-ed53792f9af2.jpg?v=1783985712"},{"product_id":"faceted-precious-opal-159ct-welo-ethiopia-bop23","title":"Faceted Precious Opal 1.59ct – Welo, Ethiopia - BOP23","description":"\u003cul\u003e\n\u003cli\u003eLocation: Welo, Ethiopia\u003c\/li\u003e\n\u003cli\u003eWeight: 1.59ct\u003c\/li\u003e\n\u003cli\u003eDimensions: 12 x 7.7 x 4 mm\u003c\/li\u003e\n\u003cli\u003eDETAILED DESCRIPTION\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003ePrecious Welo Opals – Ethiopian Gemstones with Vibrant Play of Color\nPrecious opals from the Welo region in Ethiopia are considered among the most beautiful and highest quality in the world.

Characteristics of the cabochon cut The cabochon cut is characterized by a smooth, domed upper surface without facets, while the bottom of the stone is flat or slightly concave.

In the case of hydrophane Ethiopian opals, this shape also offers a practical advantage: it reduces internal stresses and decreases the risk of cracks during water absorption. Color variability of Ethiopian opals Ethiopian opal cabochons display a wide range of colors, from light milky white shades to yellow and orange hues, with vivid red and green flashes.

They are known for their unique play of color and high transparency, which makes them highly valued 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 vibrant, 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 Mohs hardness is between 5.5 and 6.5, requiring careful handling to avoid damage.\nExtraction and Processing\nWelo opals are primarily extracted in northern Ethiopia. The first discoveries date back to the 1990s, but global interest surged around 2008 when their quality and color range gained worldwide attention. These opals quickly rivaled traditional Australian opals due to their vibrant hues.

They are known for their unique play-of-color and high transparency, making them highly prized by 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 vibrant, 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 the optical effects. The color palette 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 primarily mined in northern Ethiopia. Early discoveries date back to the 1990s, but global interest surged around 2008 when their quality and color range gained worldwide attention. These opals soon rivaled traditional Australian opals due to their vivid hues. Once extracted, the stones are cut, shaped, and polished to best enhance their natural beauty.\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, use only a slightly damp cloth. Avoid chemicals or ultrasonic cleaners, which can damage the surface and internal structure.
