Cheapest Lab Grown Diamond in India: Price by Carat

Most people assume a real diamond means lakhs, a long EMI, and a hard compromise on size. It does not have to. If you are hunting for the cheapest lab grown diamond that is still certified, still independently graded, and still a genuine diamond, the entry point in India is far lower than the showroom led you to believe. This guide is for budget first buyers: anyone who wants the lowest possible price for a certified diamond, whether it is a first pair of studs, a starter solitaire pendant, or a quiet upgrade that does not touch the savings account.

Quick summary: The cheapest lab grown diamond is a small, round, certified stone. At Ivana Jewels a 0.30 ct round starts at ₹5,700 and a 0.50 ct round at ₹9,500, both IGI or SGL certified. Round is the lowest priced cut, so the smallest round is the most affordable certified diamond you can buy.

Key takeaways

A full 1 carat certified lab grown diamond starts at ₹25,000, up to 80 percent less than a comparable mined diamond.
"Cheap" means most affordable certified, never low quality: every stone is IGI or SGL graded and set in BIS hallmarked gold.
Carat weight is the single biggest price lever, so the smallest sizes give the lowest entry price.
Finished studs, pendants, and rings sit in dedicated under ₹15,000 and under ₹25,000 edits, with the gold setting added on top.
Every piece carries lifetime buyback and exchange and home trials, so an affordable choice is still a safe one.

In this guide: why lab grown is the cheapest route to a certified diamond, a price by carat table you can trust, the five levers that lower the cost, where the most affordable finished pieces sit, and the questions buyers ask before they spend.

What makes lab grown the cheapest certified diamond

A lab grown diamond is a real diamond. It has the same carbon structure, the same hardness, and the same sparkle as a mined stone, and the FTC the two are chemically and optically identical. The only real difference is origin and price. Because a lab grown diamond is created above ground in a matter of weeks rather than mined over millennia, it costs up to 80 percent less for the same size and quality. That single fact is what makes lab grown the cheapest route to a certified diamond, and it is why Ivana is positioned as one of the most affordable lab grown diamond brands in India.

Certified means an independent laboratory, IGI or SGL, has graded the stone's cut, colour, clarity, and carat against a recognised standard, so you pay for verified quality rather than a seller's word. IGI is one of the largest such laboratories, with major branches in Surat and Mumbai. If those four grades are new to you, our 4Cs of diamonds guide explains which ones actually move the price, and where you can safely save.

Cheapest lab grown diamond price by carat

Here is the real per carat pricing for a certified lab grown diamond at Ivana, with the loose stone cost worked out for each size.

Lab grown diamond (round)	Per carat rate	Loose stone price
0.30 ct	₹19,000	₹5,700
0.50 ct	₹19,000	₹9,500
1 ct	₹25,000	₹25,000
2 ct	₹28,000 per ct	₹56,000
3 ct	₹30,000 per ct	₹90,000
4 ct and above	rises with size	On request

These are loose, certified solitaire prices, meaning the diamond only. Below 1 carat, round is the cheapest cut at ₹19,000 per carat, while other shapes such as oval, princess, and emerald sit at ₹22,000 per carat. That is why the cheapest lab grown diamond is always a small round: a 0.30 ct round at ₹5,700 is the lowest priced certified diamond on the menu, and a 0.50 ct round at ₹9,500 is the natural next step for a little more presence.

The per carat rate steps up at the 1 carat mark because a single, clean one carat crystal is far harder to grow than a smaller one: it needs a longer growth cycle and a larger flawless rough, and bigger stones carry higher reject rates, so the cost per carat climbs as size rises. Even so, at ₹25,000 for a full carat, Ivana sits at or below the typical Indian market rate of ₹30,000 to ₹55,000 per carat for a certified lab grown diamond, before you factor in lifetime buyback or a home trial.

To turn any of these stones into a finished piece, you add the gold setting, which changes the total. For a wider per carat breakdown across qualities and shapes, our lab grown diamond price guide for India goes deeper. This page keeps its eye on the lowest entry point.

Five ways to get the lowest price

The final price comes down to a few simple choices. Pull these five levers and you land at the cheapest certified number without buying something dull or ungraded.

Lever	What it does	Price impact
Start with a smaller carat	Cuts the single biggest cost driver; a 0.30 ct or 0.50 ct round still reads beautifully on studs and pendants	0.30 ct round from ₹5,700, 0.50 ct from ₹9,500
Choose a round cut	Round is Ivana's cheapest cut below 1 carat and returns the most light, so you get maximum sparkle for the spend	₹19,000 per carat against ₹22,000 for fancy shapes
Be sensible on clarity and colour	A VS clarity, near colourless stone is eye clean once set in warm gold	Avoids paying for grades the eye cannot see
Go lab grown rather than mined	The same stone, made above ground, with no quality trade off	Up to 80 percent less than a comparable mined diamond
Keep stone and setting transparent	See the certified diamond cost and the BIS hallmarked gold cost separately	No hidden making charges; 14K, 18K, or 22K gold sets the final total

The gold you choose moves the finished total, which is why the finished-piece prices below route to live product pages rather than a fixed figure.

The most affordable finished pieces, by type

The table above is the stone. Here is where the cheapest finished pieces actually live, in dedicated under ₹15,000 and under ₹25,000 edits, so you can compare current prices in one place.

Cheapest earrings: round diamond studs

Round diamond studs are the most affordable finished piece, because the setting is small and simple. Ivana's Classic Round Diamond Stud Earrings are a clean everyday pair you will reach for constantly, and the wider diamond earrings under ₹30,000 edit collects the rest of the budget options.

Cheapest pendant: a small solitaire

A single diamond on a fine chain is the most affordable way to wear a solitaire. The 0.5 Carat Lab Grown Diamond Solitaire Pendant is the classic choice, and the daintier 0.40 Pointer Lab Grown Diamond Pendant sits a notch lower. Both are certified, and the diamond pendants under ₹30,000 collection holds more.

Cheapest ring: a simple band

Ring totals move the most, because a ring uses more gold than a stud or pendant. The lowest priced certified option is a slim band: Ivana's Simple Lab Grown Diamond Eternity Ring, for example, is currently around ₹18,300, and the wider diamond rings under ₹30,000 edit holds more. If you want a single stone, our solitaire ring price for India breaks the cost down by carat and budget. The metal you pick, 14K, 18K, or 22K, sets the final number, helped by our guide to the best gold for jewellery.
