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 heart 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 heart cut engagement ring can feature a larger centre stone or higher grade 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 diamond's 4Cs.
Heart cut diamonds work well in solitaire, halo, pavé, and three-stone settings. A protective V-prong at the pointed tip is essential to prevent chipping, while additional prongs secure the rounded lobes. Dileti mounts each lab-grown heart diamond in 18K white, yellow, or rose gold, crafted in Antwerp.
Look for excellent symmetry with two matching lobes, a distinct cleft at the top, and a sharp point at the bottom, as clean proportions keep the heart outline recognisable on the finger. A classic length-to-width ratio of 0.90 to 1.10 provides a balanced silhouette. Dileti grades its lab-grown heart diamonds on the standard 4Cs.
Yes, lab-grown heart cut diamonds share the same 10 Mohs hardness as mined diamonds, making them durable for daily wear. A well-designed setting with a V-prong on the pointed tip protects the stone during everyday activities. Dileti dispatches each ring within 5 to 7 business days via FedEx across Europe.
Lab-grown heart cut diamonds of 1 carat and above are IGI-certified at Dileti, while stones under 1 carat are uncertified. The IGI report documents the diamond's cut, colour, clarity, and carat weight against recognised grading standards, so you can inspect exact grades before buying.
