The teal carries the ring.\u003c\/p\u003e\n\u003ch3\u003eThe setting\u003c\/h3\u003e\n\u003cp\u003eFour claws keep the round outline mostly open, so more of the facets and the teal color show than in a six- or eight-claw head. The polished petals under the head add shape without stones, a detail visible mainly in profile. The shank is about 1.6 millimeters and tapers slightly toward the center. The Portuguese cut and the cyan blue color are not in the diamond selector; this stone is sourced to go with this setting.\u003c\/p\u003e\n\u003ch3\u003eAbout our lab-grown diamonds\u003c\/h3\u003e\n\u003cp\u003eThe center stone is a lab-grown colored diamond — the same carbon crystal, hardness and optical behavior as a mined diamond, grown rather than extracted, with its color from trace elements or post-growth treatment as stated on its certificate. Accent stones are colorless lab-grown diamonds matched to one another for color and clarity.\u003c\/p\u003e\n\u003ch3\u003eCommon questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs four claws enough for a 1.5 ct round?\u003c\/strong\u003e\u003cbr\u003eYes. Four is the standard for rounds and leaves the most of the stone visible. The trade-off is that losing one claw matters more, so have them checked once a year.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does teal look against yellow gold?\u003c\/strong\u003e\u003cbr\u003eYellow gold warms the stone slightly, so it leans a little greener than it would in white gold. Daylight shows the most blue.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo the photographs show the exact ring I will receive?\u003c\/strong\u003e\u003cbr\u003eThe design, the cut and the carat weight, yes. Individual stones vary slightly, and colored stones in particular read differently under daylight and warm indoor light. We photograph your finished ring and send you those images before it ships.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhere does the color come from?\u003c\/strong\u003e\u003cbr\u003eLab-grown colored diamonds take their color either from trace elements during growth or from a treatment after growth, and the certificate states which. Either way the color is stable in normal wear and cleaning; avoid holding the ring in a jeweler's torch flame during any repair, which is the one thing that can alter treated color.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the center stone certified?\u003c\/strong\u003e\u003cbr\u003eYes. Every center stone of 1 carat and above ships with an IGI certificate stating carat, cut, color and clarity. Accent and pave stones are matched to the same color and clarity range but are not individually certified.\u003c\/p\u003e","brand":"CD","offers":[{"title":"10K Yellow Gold","offer_id":45905508728967,"sku":"CDW073","price":1451.0,"currency_code":"USD","in_stock":true},{"title":"10K Rose Gold","offer_id":45905508761735,"sku":"CDW073","price":1451.0,"currency_code":"USD","in_stock":true},{"title":"10K White Gold","offer_id":45905508794503,"sku":"CDW073","price":1451.0,"currency_code":"USD","in_stock":true},{"title":"14K Yellow Gold","offer_id":45905508827271,"sku":"CDW073","price":1637.0,"currency_code":"USD","in_stock":true},{"title":"14K Rose Gold","offer_id":45905508860039,"sku":"CDW073","price":1637.0,"currency_code":"USD","in_stock":true},{"title":"14K White Gold","offer_id":45905508892807,"sku":"CDW073","price":1637.0,"currency_code":"USD","in_stock":true},{"title":"18K Yellow Gold","offer_id":45905508925575,"sku":"CDW073","price":1929.0,"currency_code":"USD","in_stock":true},{"title":"18K Rose Gold","offer_id":45905508958343,"sku":"CDW073","price":1929.0,"currency_code":"USD","in_stock":true},{"title":"18K White Gold","offer_id":45905508991111,"sku":"CDW073","price":1929.0,"currency_code":"USD","in_stock":true},{"title":"Platinum","offer_id":45905509023879,"sku":"CDW073","price":2243.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/9970\/3943\/files\/IMG_20251122_104152.webp?v=1789973082","url":"https:\/\/nyxjewel.com\/products\/cyan-blue-portuguese-cut-lab-grown-diamond-engagement-ring-four-claws-plain-petal-shoulders","provider":"NYX Jewel","version":"1.0","type":"link"}
