What Decides a Labgrown Diamond Price?
According to jewellery experts, the price of any diamond - lab grown or mined - comes down to the 4Cs: cut, colour, clarity and carat of a diamond . Carat (weight/size) drives the headline number, but cut decides how brilliant the stone looks. Two stones of identical weight can differ in price by thousands of rupees because one is excellent cut to sparkle more, more light. At Goenka Jewellers, we personally look into each diamond for their best luster and the select them to be studded in our jewellery.

Why Labgrown Costs Less Than Mined
Most buyers ask how the same diamond can cost so much less. The stone is identical; the journey is not. A labgrown diamond is created in weeks and skips mining, rough sorting and a long chain of middlemen. You pay for the diamond, not the dig which is why the saving lands at 80%.
How to Get the Best Labgrown Diamond Price
• Prioritise cut, then pick a near-colourless grade that looks white to the eye.
• Compare the all-in price (stone + metal + making), not just the loose-stone quote.
• Buy only certified stones - IGI and/or GIA so you know what you are paying for.
• Factor in after-sales value: exchange, buy-back and warranty are real money.
Industry specialists recommend weighing the policy alongside the price. At Goenka Jewellers, every labgrown piece from 1 to 18 carats carries an IGI certificate and comes with a 100% exchange offer and a lifetime warranty, so your spend stays protected.
