Frequently Asked Questions
Lab-grown radiant diamonds cost significantly less than mined diamonds of the same quality, so the same budget goes further, toward a larger or higher-grade stone. They are best chosen to wear and enjoy rather than as an investment, since fine jewellery is rarely bought to resell. Dileti sets each lab-grown radiant diamond in 18K gold in Antwerp, and final pricing depends on the stone's 4Cs.
Radiant diamonds work well in solitaire, halo, pavé, and three-stone settings. Prongs at the cropped corners give security while the brilliant faceting stays on show. Dileti mounts each lab-grown radiant diamond in 18K white, yellow, or rose gold, crafted in Antwerp.
Yes, lab-grown radiant diamonds share the same 10 Mohs hardness as mined diamonds, so they suit daily wear. Durability comes from secure prongs protecting the cropped corners rather than the diamond's origin. Dileti dispatches each ring within 5 to 7 business days via FedEx, with 14-day store-credit returns.
Radiant cuts have cropped corners and brilliant-style faceting for lively sparkle, while princess cuts have sharp pointed corners and a different facet pattern. Both are geometric, but radiants protect their corners better in daily wear. Dileti offers both as lab-grown diamonds in 18K white, yellow, or rose gold.
Yes, lab-grown radiant diamonds are genuine diamonds with the same chemical, physical, and optical properties as mined diamonds, and gem laboratories grade them on the same 4Cs. The only difference is origin: they are grown in a laboratory instead of mined. Dileti sets each lab-grown radiant diamond in 18K white, yellow, or rose gold in Antwerp.
Square radiants sit at a 1.00 to 1.05 length-to-width ratio, while rectangular radiants run from 1.20 to 1.50. Both are established proportions, so the choice comes down to whether you prefer a square or an elongated outline. Dileti grades its lab-grown radiant diamonds on the standard 4Cs.
Lab-grown radiant diamonds of 1 carat and above are IGI-certified at Dileti, while stones under 1 carat are not certified. The IGI report documents the diamond's cut, colour, clarity, and carat weight against recognised grading standards, so you can check the exact grades before you buy.
