Black opals are much rarer than white opals and their color play is robust. Flashing patches of color are more distinct when they appear out of a dark background, as they do in black opals like this one. The oval cabochon opal (approx. 1.65 cts) shows an impressive play of light with large swaths of green and blue pulsing across the stone. A closer look at different angles reveals rich violet, peach, pink and orange tones. The opal is framed by a dozen old mine cut diamonds, approx. 1.44 ctw, neatly set and twinkling with warmth. \u003cbr\u003e\u003cbr\u003eMeasurements: Size 5 1\/4 US, 2.7g\u003cbr\u003eDetails: (1) black opal, 9.15 x 7.45 x 2.83mm, approx. 1.65 carats and (12) old mine cut diamonds, SI\/G-H, 1.44 ctw\u003cbr\u003eEra: 1930s-1940s\u003cbr\u003eMarkings: N\/A, tests for 14K gold\u003cbr\u003e\u003c\/p\u003e","brand":"Jean Jean Vintage","offers":[{"title":"Default Title","offer_id":48546184495287,"sku":null,"price":9392.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0563\/6400\/7607\/files\/DSC_4493_c69c636d-b1ed-4fcd-a9e5-74ad65c9ea9d.jpg?v=1781291212","url":"https:\/\/jeanjeanvintage.com\/en-nz\/products\/antique-1930s-14k-black-opal-and-old-mine-cut-diamond-halo-ring","provider":"Jean Jean Vintage","version":"1.0","type":"link"}
