The decline of lab-grown diamonds didn't happen overnight. It started in the American market—which traditionally absorbed massive quantities of commercial-grade stones—before rippling across the globe. By August 2023, the industry saw severe price drops that many buyers didn't anticipate.

Today, the market is completely flooded. The manufacturing process has scaled to a point where a pristine, 1-carat lab-grown diamond can now be sourced for as little as $400 SGD. As one of our experts noted, if production continues at this pace, these synthetic stones will eventually be sold in kiosks.

While spending $400 SGD sounds like a great deal upfront, the harsh reality hits when consumers try to upgrade or sell their jewelry.

Whether you bought your lab-grown diamond recently or years ago at only a 30% discount, the resale value is now effectively zero. There is virtually no secondary market; nobody is willing to buy them back. In contrast, while natural diamond prices have also seen market corrections recently, they still retain intrinsic monetary value and can always be resold or traded.

Because synthetic rough material is now so cheap to produce, diamond cutters no longer worry about wasting raw material to achieve a perfect shape. This means there is absolutely zero excuse for a poorly cut lab-grown diamond. Today, you can order them almost "like a pharmacy prescription"—specifying the exact VS or VVS clarity and demanding an absolutely perfect cut. If a lab-grown diamond is poorly cut, it is simply bad craftsmanship.

We are witnessing a profound cultural shift, particularly among European (German, Italian) and Asian demographics, including right here in Singapore.

When it comes to an engagement ring—the ultimate symbol of timeless love and commitment—many women are turning away from lab-grown stones because they feel "fake". A natural diamond is the hardest mineral on earth and a geological miracle that took billions of years to form. It carries an eternal, historical romance that is older than humanity itself. You simply cannot compare a rapid laboratory process to the infinite timeline of nature.

Another reason buyers are reconsidering lab-grown diamonds is the realization that the aggressive "green" and "socially responsible" marketing may be misleading.

At Dianoche, we look at the facts transparently. The shift toward lab-grown stones has actually taken livelihoods away from simple, traditional mining communities around the world. Instead of supporting these vulnerable populations, the wealth and profits are increasingly concentrated in the hands of a few tech billionaires and massive factory owners.

We live in an era dominated by artificial intelligence and synthetic content. Because of this, we believe people are experiencing "AI fatigue"—a growing rejection of mass-produced, synthetic items. The next generation is beginning to crave authenticity and natural energy, which is why the enduring prestige of a natural diamond remains undisputed.

Does this mean you should never buy a lab-grown diamond? Absolutely not. We believe every product has its perfect use case.

If you are on a strict budget, or if you want to create a heavy piece of fashion jewelry—like a multi-carat diamond tennis bracelet—lab-grown stones are an excellent, budget-friendly solution. They allow you to enjoy brilliant aesthetics without the massive financial commitment.
