{"product_id":"radiant-0-51ct-i-si1","title":"0.51 CT Radiant Natural Diamond, I Color, SI1 Clarity","description":"\u003cp\u003eThis loose diamond is a natural radiant cut weighing 0.51 carat. The radiant shape combines a rectangular outline with brilliant-style faceting, giving it the crisp corners of a step cut and the lively return of light associated with round brilliants.\u003c\/p\u003e\u003cp\u003eThe stone is graded I in color, which sits in the near-colorless range and reads warm-white in most settings, particularly when paired with yellow or rose gold. Its clarity is SI1, meaning inclusions are present but limited in visibility to the unaided eye at normal viewing distance.\u003c\/p\u003e\u003cp\u003eAt just over half a carat, this is a practical size for a solitaire engagement ring, a pendant, or one of a matched pair of studs. Radiant cuts also work well as side stones or accents in a larger composition. Because the diamond is sold loose, you can select the metal and mounting separately and build the piece around the stone rather than the other way around.\u003c\/p\u003e\u003cp\u003eOur team can discuss setting options and how the proportions of this stone will sit in a given design.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eShape: radiant cut\u003c\/li\u003e\n\u003cli\u003eCarat weight: 0.51 ct\u003c\/li\u003e\n\u003cli\u003eColor: I\u003c\/li\u003e\n\u003cli\u003eClarity: SI1\u003c\/li\u003e\n\u003cli\u003eOrigin: natural diamond\u003c\/li\u003e\n\u003cli\u003eSold loose, without a setting\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sky Diamonds","offers":[{"title":"Default Title","offer_id":53095739031832,"sku":"190-01617","price":2690.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/5015\/4520\/files\/RADIANT_20DIAMOND_20260218172649.png?v=1793384319","url":"https:\/\/skydiamonds.com\/products\/radiant-0-51ct-i-si1","provider":"Sky Diamonds","version":"1.0","type":"link"}
