Diamond Price in India (2026): The Real Per-Carat Rates
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.
Lab-grown diamond price chart (IGI-certified)
| Size | Loose stone | Set in a gold ring |

| 0.50 ct | ₹18,000 – ₹30,000 | ₹40,000 – ₹60,000 |

| 2.00 ct | ₹85,000 – ₹1,30,000 | ₹1,30,000 – ₹1,80,000 |
These are indicative market ranges. Varniya's stones sit at the quality end of them, because we hold to DEF colour, VS1-and-above clarity, and Ideal or Excellent cut.
Natural vs lab-grown, same specs

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.
