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 three-stone ring can use larger or higher-grade diamonds across all three stones 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 three-stone engagement ring features a centre diamond flanked by two side stones, often said to represent a couple's past, present, and future. The design also adds width and sparkle around the centre diamond. Dileti sets each lab-grown three-stone ring in 18K white, yellow, or rose gold in Antwerp.
Round, oval, emerald, and pear centre stones all work well in a three-stone ring, usually paired with matching rounds or tapered side stones. Balancing the side-stone size with the centre keeps the look proportional. Dileti offers these as lab-grown diamonds graded on the standard 4Cs.
Yes, three-stone rings suit daily wear, though the small accent diamonds sit in fine metalwork that benefits from occasional professional checks to keep every stone secure. Lab-grown diamonds share the same 10 Mohs hardness as mined ones, so durability depends on the setting. 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.
