A 1-Carat Diamond That Cost ₹2.8 Lakh in 2020 Now Sells for Under ₹50,000

Six years ago, a 1-carat lab grown diamond was priced close to its mined counterpart — expensive enough that most buyers didn’t bother making the distinction. That has changed in a way that reshapes every conversation about diamond jewellery today.

Between 2020 and 2024, lab grown diamond prices fell by approximately 74% globally. A 1-carat stone that retailed for around $3,410 (roughly ₹2.8 lakh at the time) in 2020 was available for under $900 by 2024 — and prices have continued softening since. In India, a comparable 1-carat lab grown diamond of G colour and VS2 clarity now costs approximately ₹25,000 to ₹40,000, depending on cut and certification. A mined diamond of identical specification still commands ₹1,50,000 to ₹3,00,000 in the Indian market.

That is not a modest discount. It is a structural shift in who can afford what.

What Drove the Price Collapse — and Why Natural Diamonds Didn’t Follow

The price drop in lab grown diamonds was not a market correction or a temporary oversupply. It was the predictable result of manufacturing technology improving faster than anyone anticipated.

Both CVD (Chemical Vapour Deposition) and HPHT (High Pressure High Temperature) methods became significantly more efficient through the early 2020s. More producers entered the market, production cycles shortened, and the cost to grow a diamond fell dramatically. Prices continued declining roughly 15–20% annually as production scaled, and the wholesale price of a 1-carat lab grown stone dropped to approximately $191 per carat by mid-2025 — even as retail prices for consumers remained considerably higher.

Natural diamonds moved in a different direction. They saw a modest price decline from their 2022 peak — around 26–30% — but their pricing is anchored by mining costs, complex international supply chains, and deliberate scarcity positioning by major producers. By 2026, a certified 1-carat natural diamond still averages $4,500 to $6,500 at retail globally, with Indian prices in the ₹1.5 lakh to ₹3 lakh range depending on grade.

The gap widened most sharply in 2022, when the price difference between lab grown and natural engagement ring diamonds grew by 67.7% in a single year. That was the moment many buyers in India and globally stopped treating the choice as a trade-off and started treating it as a straightforward value decision.

And natural diamond prices did feel the pressure. The widespread availability of lab grown stones contributed to declining average engagement ring prices globally — from roughly $6,000 in 2021 to $5,200 by 2024. Even buyers who wanted mined diamonds started spending less, partly because the alternative was so visible.

Where Prices Stand in Mid-2026

The steep part of the decline is probably over. By late 2025, premium lab grown diamonds reached what analysts describe as a production-cost floor — the point at which prices cannot fall much further without producers losing money on certified, high-quality stones. In 2026, quarterly price declines have slowed to their smallest rate in two years. The market has stabilised, not stagnated.

For buyers in India, this is meaningful. Lab grown diamonds now cost 60–80% less than mined diamonds of identical quality, and that gap appears structural rather than temporary. A 3-carat natural diamond of good quality can cost ₹18 lakh to ₹22 lakh in India. The lab grown equivalent sits around ₹1 lakh to ₹1.5 lakh. At higher carat weights, the savings don’t just stretch a budget — they make certain stones accessible that would otherwise be entirely out of reach.

The India lab grown diamond jewellery market is valued at approximately USD 453.7 million in 2026 and is projected to grow at a 14.8% CAGR through 2036, driven by retail acceptance, better consumer awareness, and clearer certification standards. Rings account for over a third of that demand, largely from bridal and engagement purchases — the same category where the price advantage is most felt.

During Indian festival seasons — Diwali, Akshaya Tritiya, wedding season — natural diamond prices tend to increase by 8–12% due to supply constraints, while lab grown diamond prices remain relatively stable. That seasonal dynamic is increasingly influencing purchase timing among Hyderabad buyers.

What This Means If You’re Shopping Today

The pricing story of the last six years essentially does two things for today’s buyer. First, it makes larger, better-quality stones genuinely affordable. Second, it shifts the question from can I afford a diamond? to what do I want to do with the budget I have?

Buyers are increasingly asking what the price gap allows them to upgrade — a bigger centre stone, a more complex setting, better metal, or a complete jewellery set rather than a single piece. That reframing is visible in how people shop for diamond rings, diamond earrings, and diamond necklaces today: the conversation has moved from justifying the category to choosing within it.

One thing worth understanding clearly: lab grown diamonds are not an investment in the financial sense. Resale values are low — typically 20–40% of original purchase price — and declining production costs mean the stone you buy today will probably cost less to replace in a few years. Buy a lab grown diamond for what it is: chemically and visually identical to a mined stone, certified to the same standards, and priced in a way that makes the quality you actually want achievable.

At Elevé Diamonds, every stone is IGI-certified and backed by over eight decades of Tibarumal’s jewellery expertise. For Hyderabad shoppers weighing options, that combination of certified quality, transparent pricing, and deep craft heritage is worth factoring into the decision — especially now that the price of a lab grown diamond no longer requires any compromise on the stone itself.
