Frequently Asked Questions
Lab-grown round 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 round diamond in 18K gold in Antwerp, and final pricing depends on the stone's 4Cs.
Round diamonds work well in solitaire, halo, pavé, and three-stone settings. Their symmetrical shape pairs with every wedding band style without modification, which makes them the most versatile choice. Dileti mounts each lab-grown round diamond in 18K white, yellow, or rose gold, crafted in Antwerp.
For a round brilliant, cut quality matters most: a well-cut stone returns the most light and out-sparkles colour or clarity gains you cannot easily see. Look for an Excellent or Ideal cut grade, then balance colour, clarity, and carat to your budget. Dileti grades its lab-grown round diamonds on the standard 4Cs.
Yes, lab-grown round diamonds share the same 10 Mohs hardness as mined diamonds, so they suit daily wear. Everyday durability comes from secure prong settings and the 18K gold band rather than the diamond's origin. Dileti dispatches each ring within 5 to 7 business days via FedEx, with 14-day store-credit returns.
No, round diamonds look smaller than elongated shapes such as oval, pear, or marquise at the same carat weight, because those shapes spread across more of the finger. Round brilliants instead return more light for greater sparkle. Dileti cuts each lab-grown round diamond to maximise brilliance.
Yes, lab-grown round 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 round diamond in 18K white, yellow, or rose gold in Antwerp.
Lab-grown round 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.
