Frequently Asked Questions
Lab-grown princess 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 princess diamond in 18K gold in Antwerp, and final pricing depends on the stone's 4Cs.
Princess diamonds work well in solitaire, halo, pavé, and three-stone settings. A four-prong setting that grips the pointed corners is essential to protect them while showing the square shape. Dileti mounts each lab-grown princess diamond in 18K white, yellow, or rose gold, crafted in Antwerp.
Yes, lab-grown princess diamonds share the same 10 Mohs hardness as mined diamonds, so they suit daily wear. The four pointed corners are the vulnerable point, so a secure four-prong setting matters more than the diamond's origin. Dileti dispatches each ring within 5 to 7 business days via FedEx, with 14-day store-credit returns.
Princess cuts usually cost less than round brilliants because the square shape keeps more of the rough crystal during cutting, while the round brilliant discards a larger share to reach its shape. Less wasted rough lowers the price. Dileti sets each lab-grown princess diamond in 18K white, yellow, or rose gold.
Yes, lab-grown princess 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 princess diamond in 18K white, yellow, or rose gold in Antwerp.
For a princess diamond, prioritise cut quality and a setting that shields the four pointed corners, since those corners chip most easily. A near-square outline, a 1.00 to 1.05 length-to-width ratio, gives the classic square look. Dileti sets each lab-grown princess diamond in 18K gold and grades it on the standard 4Cs.
Lab-grown princess 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.
