Rate last reviewed 1 November 2026. Nivara publishes its rates instead of quoting each buyer separately, so they do not move with who is asking. This is the rate you would be quoted in any of our four showrooms today.
This guide is about one carat specifically: what the stone costs, how large it actually is, and how it compares with the weights just below it. For the full rate card across every carat weight, see the lab-grown diamond price guide.

What you get in a Nivara 1 carat diamond
At Nivara there is one standard for solitaires, and every one meets it. Your 1 carat stone is VVS or IF in clarity and D or E in colour. It is an ideal cut, hearts and arrows in every round, chosen by our gemologists, and it passes 27 quality checks before it is ever set.
It arrives IGI-certified, with its report number laser inscribed on the stone, so the paper and the diamond are one and the same. And it comes with its own light performance report, so its brightness, its fire (the flashes of colour), and its contrast (the crisp balance of light and dark that makes it look alive) are not described to you. They are measured for you.
How big is a 1 carat diamond?
Carat is a measure of weight, not of size, which is why two 1 carat diamonds can look different across a table. A well proportioned 1 carat round brilliant measures roughly 6.4 mm to 6.5 mm across the top. That is the face up size you actually see once the stone is set.
Cut is what decides whether the full weight is working for you. A stone cut too deep hides some of its weight in the bottom of the diamond, so it weighs a carat but reads smaller on the hand. Every Nivara diamond is an ideal cut, hearts and arrows in every round, so the weight you pay for is the size you see.
0.90 carat or a full 1 carat?
Many buyers stop just short of a carat because, at most jewellers, the price jumps sharply at the round number. A 0.90 carat stone can look almost identical on the hand and cost noticeably less.
At Nivara that calculation is simpler: from 1 carat the rate holds at ₹50,000 per carat in a round and ₹55,000 per carat in every other shape. The difference is ₹5,000 and about a quarter of a millimetre in diameter. There is no premium for the round number, so the choice is yours to make on how it looks rather than on where the price breaks.
Why the price is the same for everyone
Our pricing is simple. At 1 carat and above, a solitaire is ₹50,000 per carat in a round and ₹55,000 per carat in every other shape. Smaller diamonds begin at ₹32,000 per carat, each priced to its size, colour, clarity and shape. Those figures do not move by who is asking. It does not start low and climb at the counter, and it is not a range that shifts across the room. The diamond you are shown is the diamond you take home.
