The opaque white body with rainbow play-of-color means the freeform outlines feel intentional rather than irregular, making them well suited to organic or nature-inspired designs.\u003c\/p\u003e\n\u003cp\u003eEthiopian opals are known for their vivid play-of-color, the optical phenomenon caused by the diffraction of light through a regular internal structure of silica spheres - and these opaque white stones, sometimes called white or milky Ethiopian opals, display that rainbow shift against a bright, clean ground. The rose cut keeps the profile low and the face open, which lets the color movement read clearly across the surface rather than getting lost in depth. Opal is relatively soft at around 5.5 to 6.5 on the Mohs scale and can be sensitive to sudden temperature changes and ultrasonic cleaning, so it is worth communicating that to your clients and keeping it away from heat during fabrication.\u003c\/p\u003e\n\u003cp\u003eDIMENSIONS\u003cbr\u003e\nSize: 9.5-12.5mm length, 2.5 depth\u003cbr\u003e\nWeight: 2.52 ct\u003c\/p\u003e\n\u003cp\u003eSTONE DETAILS\u003cbr\u003e\nVariety: Ethiopian Opal\u003cbr\u003e\nAlso Known As: Welo Opal, Wollo Opal, Ethiopian White Opal\u003cbr\u003e\nSpecies: Opal\u003cbr\u003e\nCut: Rose Cut\u003cbr\u003e\nTreatment: None\u003cbr\u003e\nHardness: 5.5 – 6.5 Mohs\u003cbr\u003e\nRI: 1.370 – 1.470\u003cbr\u003e\nSold as: 3-Stone Lot\u003c\/p\u003e","brand":"Gem Enthusiast","offers":[{"title":"Default Title","offer_id":48320766050491,"sku":"OP489","price":21.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/8214\/1627\/files\/il_fullxfull.8471507814_5ky9.jpg?v=1788445099","url":"https:\/\/gementhusiast.shop\/products\/ethiopian-opal-rose-cut-loose-gemstones-40609","provider":"Gem Enthusiast","version":"1.0","type":"link"}
