"How much does a lab-grown diamond cost?" is probably the question we hear most. The honest answer is: less than you might think, and it depends on a few things. Here is a simple guide to the typical ranges in India in 2026, and what decides where a particular piece falls.
Typical prices for loose lab-grown diamonds
Published price guides from Indian jewellers in 2026 put loose, certified lab-grown diamonds roughly in these ranges:
- Around 0.25 carat: from about ₹8,000
- Around 0.50 carat: roughly ₹15,000 to ₹35,000
- 1 carat: roughly ₹40,000 to ₹80,000
- 2 carats: roughly ₹1,00,000 to ₹2,50,000
These are guides, not fixed rates. The exact price depends on the stone's cut, colour, clarity, shape and certification, and on the seller. A natural diamond of similar size and quality typically costs several times more.
What moves the price of the diamond
- Carat: prices jump at popular sizes like 0.50, 1 and 2 carats.
- Cut: an excellent cut costs more but makes the biggest difference to sparkle.
- Colour and clarity: D to F colour and VVS clarity sit at the top of the range. G to H and VS are excellent value.
- Shape: fancy shapes such as oval, pear and emerald are often a little less per carat than round.
- Certification: an IGI or GIA report adds a little to the price and a lot to your peace of mind.
The price of finished jewellery
When you buy a ring or a pair of earrings, the diamonds are only part of the cost. You are also paying for:
- Gold: the weight of gold multiplied by the day's gold rate. 14k gold is 58.5% pure.
- Making charges: the craftsmanship of the design, which varies with how intricate it is.
- Smaller accent diamonds: pavé bands and halos add many small stones.
- GST: currently 3% on jewellery in India.
So a pair of simple lab-grown diamond studs and a full eternity band can be very different prices even with similar total carat weights.
How to get the most from your budget
- Put your money into cut first, then colour, then clarity.
- Consider a size just under a round number, such as 0.90 instead of 1 carat. It looks almost identical and can cost noticeably less.
- Choose a fancy shape like an oval, which looks bigger for its weight.
- Ask for a full price breakdown so you can compare like with like.
