{"product_id":"1-91-carat-emerald-lab-grown-diamond-f-vs1-igi-certified-700587356","title":"1.91 Carat Emerald Lab-Grown Diamond, F VS1, IGI Certified","description":"\u003cp\u003eAn emerald cut trades scattered sparkle for long, clean step facets and broad flashes of light, a quieter and more architectural look. This one is 1.91 carats and measures 8.92 × 5.73 mm face-up, a length-to-width ratio of 1.56. F is in the colorless range (D–F): it will face up icy white, in white metal or yellow gold. VS1 inclusions are minor and usually need 10× magnification to see. In an emerald of 1.91 carats that typically means eye-clean, though the grade does not say where the inclusion sits. Emerald cuts suit a clean solitaire, a bezel, or a three-stone ring with tapered baguette or trapezoid side stones. On value: we currently list 17 other F VS1 emerald diamonds between 1.72 and 2.10 carats. At $299 (about $157 per carat), this one is priced below the median of that group (median $319); 11 of them cost more. Price differences within a group usually come down to exact weight, cut details and how the stone looks, so compare the videos.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eThe photo is a still frame from this diamond's own 360° video, cropped and placed on a white background; the stone itself is not retouched.\u003c\/em\u003e\u003c\/p\u003e\u003ch2\u003eSpecifications\u003c\/h2\u003e\u003ctable class=\"cc-specs\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eShape\u003c\/th\u003e\n\u003ctd\u003eEmerald\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCarat weight\u003c\/th\u003e\n\u003ctd\u003e1.91\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eColor\u003c\/th\u003e\n\u003ctd\u003eF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eClarity\u003c\/th\u003e\n\u003ctd\u003eVS1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCut grade\u003c\/th\u003e\n\u003ctd\u003eNot graded by the lab (usual for fancy shapes)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePolish\u003c\/th\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSymmetry\u003c\/th\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eFluorescence\u003c\/th\u003e\n\u003ctd\u003eListed on the grading report\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMeasurements (L × W × D)\u003c\/th\u003e\n\u003ctd\u003e8.92 × 5.73 × 3.75 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eLength-to-width ratio\u003c\/th\u003e\n\u003ctd\u003e1.56\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eDepth\u003c\/th\u003e\n\u003ctd\u003e65.4%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eTable\u003c\/th\u003e\n\u003ctd\u003e60%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eGirdle\u003c\/th\u003e\n\u003ctd\u003eListed on the grading report\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCulet\u003c\/th\u003e\n\u003ctd\u003eListed on the grading report\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eGrading lab\u003c\/th\u003e\n\u003ctd\u003eIGI (International Gemological Institute)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eReport number\u003c\/th\u003e\n\u003ctd\u003e700587356\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eGrowth method\u003c\/th\u003e\n\u003ctd\u003eCVD (chemical vapor deposition)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003ca href=\"https:\/\/v3603853.v360.in\/vision360.html?d=126C-665-116\" target=\"_blank\" rel=\"noopener nofollow\"\u003eView the 360° video\u003c\/a\u003e · \u003ca href=\"https:\/\/www.igi.org\/VERIFY-YOUR-REPORT\/?r=700587356\" target=\"_blank\" rel=\"noopener nofollow\"\u003eVerify IGI report 700587356\u003c\/a\u003e\u003c\/p\u003e\u003ch2\u003eWhy this diamond\u003c\/h2\u003e\u003cp\u003eWhat stands out: Excellent polish and symmetry and F (colorless) color. Worth knowing: its 1.56 ratio is outside the most common range for an emerald (1.30–1.50), which changes the outline, so look at the proportions; the lab did not give an overall cut grade (normal for fancy shapes), so polish, symmetry and the video matter more.\u003c\/p\u003e\u003ch2\u003eQuestions about this diamond\u003c\/h2\u003e\u003ch3\u003eIs a VS1 emerald of 1.91 carats eye-clean?\u003c\/h3\u003e\u003cp\u003eVS1 inclusions are minor and usually need 10× magnification to see.

The report records the shape, measurements, carat weight, color, clarity, polish and symmetry, and states that the diamond is laboratory-grown. It also lists details we don't show here, such as fluorescence, girdle and culet. Enter the report number on IGI's website (the verify link on this page goes straight there) to confirm the details match this listing.\u003c\/p\u003e\u003ch3\u003eWill F color look white?\u003c\/h3\u003e\u003cp\u003eF is in the colorless range (D–F): it will face up icy white, in white metal or yellow gold.\u003c\/p\u003e\u003ch3\u003eIs this a real diamond? What does CVD mean?\u003c\/h3\u003e\u003cp\u003eYes. It is a lab-grown diamond: carbon in the same crystal structure as a mined diamond, with the same hardness and optical properties. It was grown by CVD (chemical vapor deposition). The growth method doesn't make a diamond better or worse on its own; the grades and how it looks do.\u003c\/p\u003e","brand":"Carat Confidential","offers":[{"title":"Default Title","offer_id":50808059101284,"sku":"X-148-023","price":299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0810\/7461\/8468\/files\/1-91-carat-emerald-lab-grown-diamond-f-vs1-igi-certified-700587356.jpg?v=1790531042","url":"https:\/\/caratconfidential.com\/products\/1-91-carat-emerald-lab-grown-diamond-f-vs1-igi-certified-700587356","provider":"Carat Confidential","version":"1.0","type":"link"}
