Frequently Asked Questions
Yes, lab-grown 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 every lab-grown diamond engagement ring in 18K white, yellow, or rose gold in Antwerp.
Lab-grown diamonds cost significantly less than mined diamonds of the same quality, so a solitaire can hold a larger or higher-grade centre diamond within the same budget. They are best chosen to wear and enjoy rather than as an investment, since fine jewellery is rarely bought to resell. Dileti sets each piece in 18K gold in Antwerp, and pricing depends on the diamonds' 4Cs.
A solitaire engagement ring features a single diamond as the sole focus, with no accent stones, held by a plain band and prongs. This timeless style puts all attention on the centre diamond's cut and size. Dileti sets each lab-grown solitaire in 18K white, yellow, or rose gold in Antwerp.
Every shape suits a solitaire, from round brilliant and oval to emerald, princess, and pear. Because nothing distracts from the centre stone, cut quality and proportions matter most in a solitaire. Dileti offers all popular lab-grown diamond shapes, each graded on the standard 4Cs.
Yes, a well-made solitaire suits daily wear, as a secure four or six-prong setting holds the diamond firmly while letting light in. Lab-grown diamonds share the same 10 Mohs hardness as mined ones, so a protected setting matters more than origin. Dileti dispatches each ring within 5 to 7 business days via FedEx.
Lab-grown 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.
