Lab Grown Diamond Guidance

A Mumbai jeweller told me last month that his biggest headache isn’t competition from other stores—it’s explaining to customers why a ₹2.5 lakh lab diamond might be worth ₹80,000 two years later whilst a similar mined diamond holds closer to ₹2 lakh. The conversation gets awkward fast, especially when the customer bought the lab diamond as an “investment piece” for their daughter.

This reality check is playing out across jewellery stores in Hyderabad, Chennai, and beyond. Lab diamonds have captured roughly 35% of the Indian engagement ring market as of 2026, but their investment narrative remains complicated.

The Depreciation Reality Nobody Talks About

Lab diamonds depreciate faster than a luxury car. Data from the Gem and Jewellery Export Promotion Council shows that lab diamonds lose approximately 60-70% of retail value immediately after purchase, compared to 25-40% for mined diamonds. But here’s where it gets interesting—this depreciation curve isn’t necessarily permanent.

Consider the smartphone analogy. A top-tier iPhone costs ₹1.5 lakh today and might fetch ₹60,000 next year, yet millions buy them knowing this. The value equation isn’t purely about resale—it’s about utility, enjoyment, and status during ownership.

Yet jewellers in Hyderabad’s traditional markets like Abids still report customer shock when discussing lab diamond resale values. The disconnect stems from decades of diamond marketing that emphasised investment potential alongside emotional value.

Market Dynamics Shifting Beneath Our Feet

The lab diamond market in India grew 89% in 2025, reaching ₹12,400 crores according to industry reports. This growth is reshaping how we think about diamond value entirely.

Production costs for lab diamonds continue declining—roughly 15% annually since 2023. A one-carat lab diamond that cost jewellers ₹45,000 in 2024 probably runs closer to ₹35,000 today. This deflationary pressure creates a challenging investment environment but an excellent consumer opportunity.

Meanwhile, consumer acceptance rates tell a different story. Surveys from the India Gem & Jewellery Federation indicate that 73% of millennials in metro cities view lab diamonds as “real diamonds,” up from 51% in 2024. The perception shift is accelerating faster than industry experts predicted.

Regional variations matter enormously. Chennai shows higher acceptance rates (78%) compared to traditional jewellery markets in Rajasthan (42%). Hyderabad sits comfortably in the middle at 69%, probably influenced by its tech-savvy population.

But acceptance doesn’t automatically translate to investment confidence.

What “Investment Value” Actually Means

Traditional diamond investment logic relied on scarcity, marketing monopolies, and generational wealth transfer. Lab diamonds break this model completely.

The question becomes: should we judge lab diamonds by traditional investment metrics, or develop new frameworks?

Liquidity remains problematic. Most jewellers accept trade-ins for lab diamonds at 20-30% of original retail, compared to 40-60% for mined diamonds. Secondary markets for lab diamonds barely exist outside major metros.

Storage and insurance costs are identical regardless of diamond origin. A ₹3 lakh lab diamond requires the same security precautions as its mined equivalent.

Appreciation potential appears limited given production scalability. Unlike mined diamonds, where supply constraints create artificial scarcity, lab diamonds can be produced on demand as technology improves and costs decline.

And the depreciation accelerates with size. Larger lab diamonds (2+ carats) face steeper value drops because production economics favour larger stones—making them relatively more abundant.

The Emotional Investment Paradox

Here’s something curious: customers often report higher satisfaction with lab diamond purchases despite understanding the depreciation. Research from the Consumer Behaviour Institute suggests that knowing you paid less for equivalent beauty actually enhances enjoyment rather than diminishing it.

A software engineer in HITEC City explained it perfectly: “My wife’s lab diamond engagement ring looks identical to her sister’s mined diamond that cost three times more. Every time someone compliments it, she feels clever rather than cheated.”

This psychological dynamic challenges traditional investment thinking. If the primary value comes from wearing and displaying the diamond, rapid depreciation matters less than initial acquisition cost.

Industry Forecasts and Expert Predictions

The Bain & Company luxury report for 2026 projects that lab diamonds will capture 45-50% of global diamond demand by 2028. India’s share could reach 60% given price sensitivity and growing environmental consciousness.

Production capacity continues expanding. New facilities in Gujarat and Tamil Nadu will add approximately 2.5 million carats of annual production by late 2026, further pressuring prices.

Technology improvements remain steady. HPHT and CVD processes are becoming more efficient, but we’re probably approaching physical limits for major cost reductions. Industry experts suggest that lab diamond prices may stabilise around 2027-2028 rather than continuing their steep decline.

Investment funds have started accumulating mined diamond parcels, betting on supply constraints as several major mines approach depletion. Lab diamonds face the opposite dynamic—investment flows towards production capacity rather than finished stones.

Regional Market Realities in India

Hyderabad’s diamond market reflects broader Indian trends whilst maintaining distinct characteristics. The city’s sizeable IT population drives demand for lab diamonds, with several local jewellers reporting that 40-50% of engagement ring sales now involve lab stones.

Traditional families still prefer mined diamonds for significant occasions. Wedding jewellery sets above ₹5 lakhs rarely feature lab diamonds, regardless of customer age or education level.

But everyday jewellery tells a different story. Diamond studs, pendants, and casual rings increasingly feature lab stones across all demographics.

Local jewellers like those in the heritage Begum Bazaar area have adapted by positioning lab diamonds as “daily wear” options whilst reserving mined diamonds for “special occasion” pieces. This segmentation strategy acknowledges different value perceptions whilst serving both markets.

The Inheritance Question

What happens when today’s lab diamond purchases become tomorrow’s family heirlooms?

Generational wealth transfer traditionally relied on jewellery maintaining or appreciating in value. Lab diamonds complicate this assumption significantly.

Consider a scenario: A ₹2 lakh lab diamond engagement ring purchased in 2026 might be worth ₹50,000 in 2056 (accounting for inflation and continued price declines). The same money invested in a diversified portfolio could potentially grow to ₹15-20 lakhs over thirty years.

Yet this analysis assumes purely financial value. Family heirlooms carry emotional premiums that resist market logic. A grandmother’s engagement ring has value beyond its material worth, regardless of origin.

The inheritance question probably won’t be answered until the first generation of lab diamond buyers starts passing jewellery to their children, sometime around 2050-2055.

Comparing Investment Perspectives

Mined diamonds face their own investment challenges despite better resale values. Market manipulation by major producers artificially supports prices, but this control is weakening as lab alternatives gain acceptance.

Climate concerns increasingly influence luxury purchases among younger consumers. ESG investing principles that favour sustainable options may eventually benefit lab diamonds, though this remains speculative.

Portfolio diversification logic suggests avoiding both mined and lab diamonds as investments. The correlation between diamond prices and other asset classes offers minimal diversification benefits, whilst volatility remains high and returns unpredictable.

Real estate, equity, or fixed deposits provide superior investment characteristics for most Indian investors compared to any diamond category.

Beyond Traditional Metrics

Perhaps we’re asking the wrong questions about lab diamond investment value.

Instead of comparing to mined diamonds, consider comparing to other luxury purchases. A ₹2 lakh Swiss watch faces similar depreciation patterns whilst providing less versatility than diamond jewellery. Luxury handbags depreciate even faster whilst offering shorter useful lives.

The lab diamond value proposition might be: maximum beauty and status per rupee spent, rather than maximum investment returns.

This reframing aligns with how most people actually purchase jewellery—for personal enjoyment rather than portfolio construction.

At stores like Elevé Diamonds, which specialise in lab grown options, customers increasingly understand this distinction. The conversation shifts from “will this hold value?” to “how much beauty can I afford?”

Market Predictions for 2027-2030

Lab diamond prices will probably stabilise within 18-24 months as production costs approach physical limits and market saturation slows growth. This stabilisation could improve investment characteristics, though appreciation remains unlikely.

Consumer acceptance will continue growing, potentially reaching 80% in metro markets by 2028. This acceptance creates larger secondary markets, possibly improving liquidity over time.

Technology breakthroughs could disrupt everything. Quantum dot manufacturing or advanced AI-controlled growth processes might either slash costs further or improve quality dramatically. Both scenarios would affect investment calculations significantly.

Regulatory changes remain possible. The government has discussed mandatory disclosure requirements and standardised certification processes that could impact market dynamics.

---

The investment question around lab diamonds reflects broader changes in how we value luxury goods in an era of technological abundance. Traditional scarcity-based value models struggle when scarcity becomes optional.

Smart buyers in 2026 purchase lab diamonds for the right reasons: exceptional beauty at accessible prices, ethical sourcing, and personal enjoyment. Those seeking investment returns would probably do better elsewhere.

The real worth of lab diamonds lies not in their future market value, but in democratising diamond ownership for a generation that values experiences over assets and sustainability over status symbols.
