Diamond Price in India (2026): The Real Per-Carat Rates
What do diamonds cost in India in 2026? Full per-carat price chart for lab grown and natural diamonds, what drives the rate, and how to get the best value.
Diamond pricing in India is often opaque: most jewellers quote a final number with the markup baked in. This page shows the actual per-carat rates so you can judge any quote. In short, a certified 1-carat lab-grown diamond runs about ₹35,000 to ₹55,000 as a loose stone in 2026, while the same in a natural diamond is ₹2.5 to 4 lakh.

What actually drives the price
- The 4Cs: cut, colour, clarity and carat. Carat has the steepest effect, and prices jump at round magic sizes.
- Certification: GIA-certified stones cost about 5 to 10% more than IGI for the same grade. See IGI vs GIA.
- The setting: 14KT versus 18KT gold, and design complexity, add to a finished ring.
- GST: 3% GST applies to diamond jewellery in India.
How to get the best value
Buy lab-grown so you can afford the best grades, insist on certification, and remember that a brilliant cut does more for beauty than extra carat weight. This is exactly how Varniya prices every stone: DEF colour, VS1 and above, Ideal or Excellent cut, at a transparent per-carat price.
