A 1 carat diamond is the benchmark engagement ring size in India, and its price depends first on whether it is natural or lab grown, then on colour, clarity and cut. A natural 1 carat diamond is priced in lakhs. A lab grown 1 carat diamond at the same grades is a fraction of that, and in a finished ring the gold is often a bigger part of the price than the stone. Ivana Jewels recalculates prices daily against the gold rate, so this page explains what drives the number and links to today's 1 carat ring prices rather than quoting a figure that would go stale.
1 carat diamond price: what moves it
| Factor | Effect on a 1 carat price | Value choice |
|---|---|---|
| Natural vs lab grown | The largest factor by far; natural is several times the lab grown price at identical grades | Lab grown, for the same stone at a fraction of the cost |
| Colour | D to F costs most; each step down to H reduces price with no visible change in most settings | G or H in white gold; H to J in yellow or rose gold |
| Clarity | VVS and IF carry a premium for a difference you cannot see at 1 carat | VS1 or VS2, eye-clean |
| Cut | Excellent or Ideal returns the most light and is worth paying for | Excellent |
| Shape | Round costs most per carat; oval, pear, cushion and emerald cost less and look larger | Oval or pear for visible size |
| Exact weight | Prices step up at 1.00 carat; 0.90 to 0.99 carat looks identical and costs less | A 0.9 to 0.95 carat stone if budget is tight |
How big is a 1 carat diamond?
Carat is weight, not size. A 1 carat round brilliant measures about 6.5 mm across; a 1 carat oval about 7.7 x 5.7 mm; a 1 carat pear about 8.5 x 5.5 mm; a 1 carat princess about 5.5 mm square; a 1 carat cushion about 5.9 mm; a 1 carat emerald cut about 6.7 x 4.8 mm. Elongated shapes cover more of the finger at the same weight, which is why oval and pear 1 carat rings are popular in India.
What a 1 carat lab grown diamond ring costs, and why
A finished ring price is the diamond plus gold plus making charges plus 3% GST. For a 1 carat lab grown solitaire the diamond and the gold are usually of the same order, so the ring price moves with the daily gold rate. The same 1 carat stone in a slim 9kt or 14kt band costs noticeably less than in a heavy 18kt cathedral setting, and a halo adds small diamonds and gold on top. Product pages at Ivana Jewels list the solitaire weight, small diamond weight and gold weight separately so you can see what you are paying for.
1 carat lab grown vs 1 carat natural
The two stones are chemically and optically identical and are graded on the same scale by the same laboratories. The difference is origin and price. With the budget of a natural 1 carat ring, a lab grown buyer can typically choose a 2 carat stone, or a 1 carat stone at top grades in a heavier setting.

Frequently asked questions
What is the price of a 1 carat lab grown diamond ring in India?
It depends on the stone's grades, the gold weight and purity, and today's gold rate. See the live 1 carat collection for current prices; every ring lists its diamond and gold weight.
Is a 1 carat diamond big enough for an engagement ring?
It is the most chosen size in India. It is clearly visible on any hand and comfortable for daily wear.
Does 1 carat mean the centre stone or the total?
Either, so check. A solitaire described as 1 carat has a 1 carat centre stone; a halo or side-stone ring may quote total carat weight. The product page states both.
Which shape looks biggest at 1 carat?
Marquise, then pear and oval. Round is in the middle; princess and cushion look slightly smaller across.
Should I buy 0.9 carat instead of 1 carat?
If the budget is tight, yes. A 0.90 to 0.95 carat stone is visually the same size and avoids the price step at 1.00 carat.
