Seven Questions. One Honest Article.

Walk into any jewellery conversation in Hyderabad right now and lab grown diamonds come up within minutes. Couples planning engagements ask about them. Parents buying anniversary gifts ask about them. And yet, for every buyer who has done the research, there are three more who are still working from half-remembered facts or things they read two years ago.

This article answers the seven questions we hear most often — directly, with current data, and without the fluff. If you are considering a lab grown diamond purchase in 2026, start here.

1. Are Lab Grown Diamonds Real Diamonds?

Yes, without qualification. A lab grown diamond is chemically, physically, and optically identical to a diamond formed underground. Both are pure carbon arranged in a cubic crystal lattice — the same structure that gives diamonds their hardness (10 on the Mohs scale) and their ability to bend and scatter light the way they do.

The distinction people reach for — that one is “natural” and one is “lab made” — is a distinction of origin, not of composition. As the GIA itself acknowledges, lab grown diamonds share the same chemical and physical properties as mined stones. Imitations like cubic zirconia or moissanite have different chemical structures entirely, which is why trained gemologists can spot them immediately. Lab grown diamonds, by contrast, require advanced spectroscopy equipment to distinguish from mined ones. That tells you something.

In India, the Bureau of Indian Standards enforced new terminology rules (IS 19469:2025) in January 2026, mandating that retailers label products explicitly as “laboratory-grown diamond” or “laboratory-created diamond” — a formal acknowledgment that these are, in fact, diamonds.

2. How Are Lab Grown Diamonds Made?

Two methods dominate the industry: CVD (Chemical Vapor Deposition) and HPHT (High Pressure, High Temperature).

In CVD, a thin diamond seed plate is placed inside a vacuum chamber. The chamber is filled with a carbon-rich gas mixture — typically methane and hydrogen — and energised to around 2,000°C using microwave plasma. Carbon atoms break away from the gas and deposit onto the seed, layer by layer, crystallising into a diamond over two to six weeks. CVD tends to produce Type IIA diamonds with very few metallic inclusions, which is why it dominates the Indian market.

HPHT works differently. It subjects a carbon source to extreme pressure (around 5–6 GPa) and temperatures near 1,500°C, mimicking the conditions roughly 100 miles beneath the earth’s surface where natural diamonds form. The process can complete in a matter of days and tends to produce excellent crystal uniformity, particularly for larger stones above 3 carats.

Both methods produce genuine diamonds. The growth method is noted on your certification report, but it does not determine quality — the 4Cs do.

3. How Much Do Lab Grown Diamonds Cost Compared to Natural Diamonds?

This is where the numbers become hard to ignore. In 2026, lab grown diamonds cost 70–85% less than natural diamonds of equivalent grade. A 1-carat natural diamond with high colour and clarity grades typically retails between $5,200 and $6,800 internationally. A lab grown diamond with the same specifications costs $900 to $1,400.

In the Indian market, a 1-carat lab grown diamond in a loose certified stone ranges from approximately ₹25,000 to ₹55,000 depending on cut, colour, and clarity — a fraction of what a comparable mined stone would cost. The gap widens at higher carat weights. A $3,000 budget, for instance, buys roughly a 2-carat lab grown diamond or a 0.5-carat natural diamond. The visual difference between those two stones is dramatic.

Prices for lab grown diamonds have been declining as CVD production technology improves and domestic manufacturing scales up — India produced over 3 million lab grown diamonds in 2023, with cities like Surat supplying the bulk of global output. Analysts suggest prices are approaching a production cost floor in 2026, meaning the steep annual drops of the past few years are likely to slow.

For buyers in Hyderabad, this pricing reality means a meaningful upgrade in stone size, setting quality, or both — without stretching a budget beyond comfort.

4. Can You Tell a Lab Grown Diamond Apart from a Mined Diamond?

Visually, no. Even professional gemologists cannot tell the difference without specialised equipment. Both types pass standard diamond testers. Both display the same fire, brilliance, and scintillation. The difference only becomes apparent under advanced spectroscopy that identifies trace growth patterns specific to CVD or HPHT processes — tools that are not part of any standard jewellery purchase or appraisal.

What this means practically: the person sitting across from you at dinner will not be able to tell. The stone in your ring will look exactly as it should — because it is, by every measurable standard, a diamond.

Lab grown diamonds also tend to achieve higher average clarity and colour grades than mined stones, largely because controlled growth conditions eliminate many of the random inclusions that form naturally underground. A buyer working with a fixed budget often ends up with a visually superior stone compared to what the same money would buy in the mined market.

5. Are Lab Grown Diamonds Certified?

Yes, and certification matters. Every reputable lab grown diamond should come with a grading report from an independent gemological laboratory — most commonly IGI (International Gemological Institute) or GIA (Gemological Institute of America).

IGI is the dominant certification body for lab grown diamonds in India. It has graded lab grown stones since 2005, and its reports cover the full 4Cs — cut, colour, clarity, and carat weight — along with the growth method (CVD or HPHT) and a unique report number that can be laser-inscribed on the diamond’s girdle. For Indian buyers, IGI certification is widely understood by retailers and provides a clear, standardised basis for comparison.

GIA, which pioneered the 4Cs grading system for natural diamonds, shifted its approach to lab grown grading in late 2025, replacing traditional letter grades with a descriptive “Quality Assessment” system. This has created some inconsistency in how buyers compare stones across different certificates, and is one reason IGI has become the practical standard for lab grown purchases in India.

The certificate is not just paperwork. It is the independent verification that the stone you are buying matches the quality you are paying for. A diamond without a certificate from a recognised lab is a diamond you are taking on trust alone.

At Elevé Diamonds, every lab grown diamond is certified to global standards — a baseline expectation for any serious purchase.

6. Are Lab Grown Diamonds Ethical and Sustainable?

The ethical case is clearer than the environmental one, so it is worth separating the two.

On ethics: lab grown diamonds are produced without involvement in mining supply chains. There is no question of conflict sourcing, no community displacement, no labour conditions tied to remote mining operations. For buyers who want complete traceability in their purchase, lab grown is the only category where that is straightforwardly possible.

On environment: the picture is more nuanced. Lab production eliminates land clearance, habitat destruction, and the large-scale water use associated with open-pit mining. It also removes the extended multi-country supply chain that mined diamonds travel through before reaching a retailer. However, the laboratory processes themselves — particularly HPHT — are energy-intensive. The sustainability advantage depends significantly on whether the facility runs on renewable power.

The trend is moving in a cleaner direction. As renewable energy adoption increases in manufacturing, the carbon footprint of lab grown production continues to fall. For buyers in 2026, the ethical sourcing argument is robust; the environmental argument is strong in principle and improving in practice.

Younger buyers in India are weighing both factors. Bridal jewellery demand for lab grown stones is growing precisely because couples want a purchase that reflects their values as much as their aesthetic.

7. Do Lab Grown Diamonds Hold Their Value?

This is the question most buyers ask last, but probably should ask earlier. The honest answer: lab grown diamonds do not hold resale value the way natural diamonds do.

Natural diamonds typically retain 40–60% of their retail value on resale. Lab grown diamonds, by contrast, have seen their market prices fall significantly as production has scaled — prices have dropped roughly 95% from their 2018 peak. The resale market for lab grown stones reflects this: many jewellers offer little to no buyback on lab grown diamonds, and secondary market prices tend to be a fraction of the original purchase price.

But this framing misses how most buyers actually use fine jewellery. The vast majority of engagement rings and sentimental pieces are never sold. If a ring stays on your finger for decades, its resale value is theoretical. What matters is what you got for your money at the time of purchase — and on that measure, lab grown diamonds offer a size, quality, and design budget that mined diamonds simply cannot match at the same price point.

The more useful question is not “will this hold value?” but “what do I want this purchase to do?” For a piece meant to be worn and loved, lab grown delivers. For a purchase treated as a financial instrument, natural diamonds have the stronger track record.

At Elevé Diamonds, the collection spans diamond rings, earrings, necklaces, and pendants — all lab grown, all certified, and all built on over eight decades of Tibarumal’s jewellery expertise. The combination of heritage craftsmanship and modern stone technology is what makes the difference between a diamond that looks right and one that feels right.

The Short Version

Lab grown diamonds are real diamonds — same carbon, same hardness, same sparkle — grown in a controlled environment rather than extracted from the earth. They cost 70–85% less than mined equivalents, are graded by the same gemological standards, cannot be distinguished by the naked eye, and carry a cleaner ethical sourcing story. Their resale value is lower, which matters for some buyers and not at all for others.

In 2026, India’s lab grown diamond jewellery market is valued at approximately $453.7 million and is projected to grow at nearly 15% annually through 2036. The category has moved well past niche status. It is, for a growing number of buyers in Hyderabad and across India, simply the default choice for fine diamond jewellery.
