Why Diamonds Are No Longer a Smart Investment in the Age of Lab-Grown Gems
Why Diamonds Are No Longer a Smart Investment in the Age of Lab-Grown Gems
For decades, diamonds were considered a symbol of wealth, status, and timeless beauty. Many people also believed that buying diamonds was a smart investment, something that would retain or grow in value over time. But today, in the era of lab-grown diamonds, that belief is quickly losing ground. Here's why diamonds, especially traditional white diamonds, are no longer a wise choice for investment.
1. Lab-Grown Diamonds Have Changed the Game
Lab-grown diamonds are chemically and physically identical to natural diamonds. They look the same, sparkle the same, and are often certified by the same gemological institutes like GIA or IGI. However, unlike natural diamonds that take billions of years to form deep within the Earth, lab diamonds can now be made in just weeks—or even minutes—with advanced technology.
This ability to mass-produce high-quality diamonds has dramatically increased supply, which leads to a basic economic truth: more supply means lower prices.
2. Falling Prices and Poor Resale Value
As lab-grown diamonds become more common, prices continue to fall. Over the past few years, lab diamond prices have dropped by over 60%. You can now buy a 1-carat lab-grown diamond for a fraction of what a natural one costs, and the price is still declining.
Even natural diamonds are seeing a drop in resale value. Most jewelers won’t buy back lab-grown diamonds at all, and natural diamonds typically lose 30% to 50% of their value the moment they leave the store.

3. A Brief History of Diamond Prices
1980s–2000s: Diamond prices were relatively stable due to De Beers' strong control over global supply.
2010s: Growing concerns over blood diamonds and ethical sourcing began affecting buyer sentiment. Prices fluctuated but remained high.
2015–2020: Lab-grown diamonds began entering the market seriously. Prices of natural diamonds saw slower growth, while lab diamonds dropped by ~20–30%.
2021–2024: Price drop accelerated. Lab-grown diamond prices fell over 60%, and natural diamonds started losing ground in resale value.
In today's market, a lab-grown 1-carat diamond can cost as little as ₹60,000–₹80,000, compared to ₹2 lakh or more for a natural equivalent just a few years ago.
4. The Illusion of Rarity
The idea that diamonds are rare is a myth created by marketing. In the early 20th century, the diamond cartel De Beers famously ran ad campaigns promoting the slogan “A diamond is forever.” This was designed to create emotional value and the illusion of scarcity.
In reality, diamonds are one of the most abundant gemstones on Earth, and lab-grown diamonds have made them even more accessible.
5. Ethical and Environmental Factors
Lab-grown diamonds are generally considered more ethical and eco-friendly than mined diamonds. They avoid the human rights issues and environmental destruction often associated with traditional diamond mining. For consumers who care about ethics and sustainability, lab-grown gems are the better choice—but again, not as an investment.
6. What Still Holds Investment Value?
If you're looking for assets that appreciate or hold value:
Gold remains a time-tested, globally recognized store of value.
Silver is used in various industries and also holds investment appeal.
Rare colored diamonds—like blue, pink, or red—can still be valuable, but these are for high-end collectors and not average buyers.
Conclusion: Diamonds Are for Beauty, Not for Building Wealth
Lab-grown diamonds are a scientific marvel—beautiful, ethical, and affordable. But when it comes to investing, the landscape has changed. Mass production means lower value and minimal resale potential. If you love diamonds, buy them for what they are: stunning accessories. But if you're looking to invest, you're better off putting your money in assets that truly grow over time.
In the age of lab-grown gems, diamonds have lost their sparkle as an investment.
