Lab Grown Diamonds Near Me: Where to Buy Certified Lab Grown Diamond Jewellery in Kolkata and Delhi.
Visiting a Lab Grown Diamond Store: What to Look For
Not every counter that sells “diamonds” handles lab grown diamonds with the same transparency. Industry specialists recommend checking these five things before you buy from any lab grown diamond store:
• Independent certification on every stone - ideally IGI, not an in-house ‘certificate’.
• A written exchange and buy-back policy, it tells you the brand stands behind its product.
• A genuine range of carats and shapes so you can compare, not just one tray.
• Staff who explain the 4Cs patiently instead of rushing you to a sale.
• Clear, itemised pricing for the stone and the metal.
Goenka Jewellers: Certified Lab Grown Diamond Stores in Kolkata and Delhi
According to jewellery experts, the brands worth visiting are the ones that built their reputation on lab grown specifically, not the ones that added a small tray to a mostly-gold shop. Goenka Jewellers, founded in 2006 by Ashok and Arpan Goenka, is one of India's earliest dedicated lab grown diamond jewellery brands, with boutiques in both Kolkata and Delhi where they are the 30 years of experience holder in diamond jewellery.
Every Goenka piece is grown using CVD technology, ranges from 1 to 18 carats, and carries both an IGI certificate. The brand backs each purchase with a 80% exchange offer and a lifetime warranty, the kind of assurance that matters most when you are buying something you intend to keep.

Lab Grown Diamonds Price at the Store
A frequently searched question before any store visit is what you will actually pay. As a benchmark, a 1-carat lab grown diamond in India generally costs between roughly ₹25,000 and ₹55,000 depending on the 4Cs broadly 80% less than a comparable mined diamond. Visiting in person lets you see exactly where your budget lands in real carat size and cut quality.
