Lab Grown Diamond Engagement Rings

Yes. Lab grown diamonds are real diamonds -they look identical to mined diamonds because they are physically and chemically the same material. A jeweller, a gemologist, and a diamond tester cannot distinguish a lab grown diamond from a mined diamond without specialised equipment. In an engagement ring setting, a certified lab grown diamond of equivalent cut, colour, and clarity is visually indistinguishable from a mined diamond of the same grade.

A 1 carat lab grown diamond engagement ring with IGI or SGL certification in 18KT gold typically costs between ₹75,000 and ₹1,50,000 in India, depending on cut grade, colour (D–F for white gold settings), and clarity (VS1 or above recommended). A round brilliant in Excellent cut at D/VS1 will sit toward the upper end of that range; a G/VS2 equivalent in yellow gold toward the lower end. Prices are subject to current gold rate movements.

The round brilliant cut is the most popular globally for its maximum light return across all directions. The oval cut is the fastest-growing choice for buyers who want a larger-appearing stone and a finger-lengthening silhouette. The cushion cut suits buyers who prefer a softer, vintage aesthetic. The emerald cut is for buyers who prioritise clarity and a sophisticated step-cut appearance. There is no universally best cut -it depends on the wearer's hand shape, style preference, and the setting chosen.

Both IGI (International Gemological Institute) and GIA (Gemological Institute of America) are internationally recognised independent grading institutions that certify lab grown diamonds using the same 4Cs framework -cut, colour, clarity, and carat weight. GIA is the older institution and the global standard for mined diamonds. IGI has become the dominant certification body for lab grown diamonds globally, with the largest volume of lab grown diamond grading reports. Both certifications are equally valid for purchasing decisions.

A 3 carat lab grown diamond engagement ring with IGI certification in 18KT gold typically costs between ₹2,50,000 and ₹4,50,000+ in India, depending on cut grade, colour, clarity, and setting complexity. Oval and cushion cuts in 3ct tend to sit slightly below round brilliant pricing at the same quality grade. All prices are subject to gold rate movements at the time of purchase.

Yes. Custom lab grown diamond engagement rings are available through Lucira's experience centre advisors in Mumbai, Pune, and Noida.

A custom consultation appointment can be booked at any Lucira experience centre to begin the process.

A 2ct lab grown diamond engagement ring has a centre stone with a diameter of approximately 8.1mm (round) -a strong visual presence on most hand sizes. A 3ct round brilliant has a diameter of approximately 9.3mm -immediately visible and significant across most outfits and lighting conditions. The price difference is substantial, but meaningfully lower than the equivalent jump in mined diamond pricing at the same certified quality grade.
