Natural diamonds are more than just an investment
Russell Mehta reflects on the diamond industry’s evolution, noting a shift from romantic experiences to transactional purchases due to increased transparency and lab-grown alternatives. While the market faces fluctuations, natural diamonds retain intrinsic value, rarity, and emotional significance, distinguishing them from commodities like gold.
Consumer perspectives have shifted significantly over the 40years that I have been in the diamond business. When I started out in the early 1980s, buying a diamond was a romantic, emotional experience. Its mystique was linked to its rarity, its perceived uniqueness, and the joy of discovery during the shopping process. This traditional view of diamonds has shifted with the rise of certification, transparency, and the accessibility offered by the internet. The diamond market has become more commoditized, where consumers can compare prices, examine flaws, and get a better understanding of what they are buying, often without stepping into a store. The process of acquiring a diamond, once filled with romance, has become increasingly transactional.

Recent reports have raised doubts over diamonds as viable investments, often comparing them to gold or other financial assets. Unlike other luxury items, such as designer bags, diamonds’ value comes from a combination of art, history, and sentiment—an acquisition that can be passed down through generations. I own a diamond from my grandfather, and its value to me is immeasurable; no price tag could ever capture its significance.
Unlike gold, with which diamonds are erroneously compared to, or art, diamonds occupy a middle ground. While not as liquid as gold or as illiquid as art, natural diamonds retain intrinsic value over time.
For example, I have collected numerous works of art, but only a handful have appreciated significantly over two decades. This unpredictability does not make the art any less valuable to me, but it highlights the varied nature of investments. I cherish the stories behind my art collection—how I discovered each artist and acquired each piece alongside my wife. That does not mean diamonds do not serve as a form of security in times of crisis. History has shown that in turbulent moments, diamonds have been portable assets that can be used to re-establish stability.
The value of diamonds can fluctuate, but it doesn’t depreciate—nor does it get damaged—as quickly as other commodities. According to a Bain & Co report, on an average, prices have increased by 3% year-on-year over the last 35 years.
The rarity of natural diamonds will only grow, as their supply is limited. No significant new diamond deposits have been discovered in the past two decades and the current mines are gradually depleting. The natural pink diamonds that the Argyle mine in Australia produced over 30 years, for instance, are now coveted collectors’ items, providing extraordinary returns as the Argyle mine is now closed.

The introduction of lab-grown diamonds has added a layer of variety to the industry. These diamonds, created in a controlled environment, are more affordable and abundant compared to natural diamonds. While they share the same physical properties, they lack the rarity, preciousness, and emotional weight of natural diamonds. They follow Moore’s Law—as technology improves, their production becomes cheaper, their quality better, and their size larger—further reinforcing their status as a manufactured commodity, rather than a unique and naturally-available gem.
Their rise reflects the broader trend of commoditization in the diamond industry. Some consumers may be drawn to the lower price point of lab-grown diamonds. For example, it may work for the 25-27 year-old on his—dare I say—first marriage proposal. But for his 10th wedding anniversary, his gift would be the real thing, a natural diamond.
After an unprecedented boom in 2021 and 2022, the market has contracted, with the value of global retail-studded diamond jewellery declining from $90 billion to approximately $75 billion in 2024. This was due in part to slowing luxury demand in China and some cannibalisation from lab-grown diamonds in the U.S. While the diamond market may go through its cycles, the emotional and lasting value of real diamonds will continue to endure.
I see this as an industry that’s in the business of bringing joy to consumers, through birthdays, engagements, anniversaries and gifting. Life is an assimilation of memories, time spent with loved ones and natural diamonds are attached to landmarks in life. It’s the only commodity that’s a brand in itself.

Titanium Jewellery Manufacturing: Convergence Of Advanced Manufacturing, AI, and Surface Chemistry
For Trade Professionals, Understanding The Tech Powering This Trend Isn’t Just Academic—It’s The Key To Navigating The Next Decade Of Luxury Design.
Titanium has officially broken free from its industrial roots. Long reserved for aerospace engineering and medical implants, this ultra-tough metal has been repositioned at the pinnacle of luxury watchmaking and high jewelry. Driven by a convergence of advanced manufacturing, AI, and surface chemistry, titanium is giving traditional precious metals a run for their money.
For trade professionals, understanding the tech powering this shift isn’t just academic—it’s the key to navigating the next decade of luxury design. Here are the core innovations driving the titanium revolution.
1. 3D Printing & Direct Metal Laser Sintering (DMLS)
Working with titanium presents a notorious metallurgical hurdle: its extreme melting point () makes traditional casting and soldering nearly impossible. Enter Direct Metal Laser Sintering (DMLS).
By using high-powered lasers to fuse microscopic titanium powder layer by layer, designers can bypass traditional workbench limitations entirely. This additive manufacturing capability allows ateliers to produce complex, hollow, and lattice-like organic structures. The result? Massively oversized, avant-garde statement pieces that remain remarkably lightweight and structurally indestructible.
2. Precision via AI-Driven CNC Machining
Titanium’s legendary hardness routinely destroys standard bench tools, making traditional hand-carving or standard machining painfully slow and cost-prohibitive. To solve this, forward-thinking manufacturers are deploying AI-driven Computer Numerical Control (CNC) machining.
AI algorithms optimize tool paths in real-time, reducing tool wear while carving intricate geometries at unprecedented speeds. Furthermore, these smart CNC systems achieve an ultra-refined grain size on the metal’s surface—a crucial prerequisite for achieving a flawless, mirror-like finish and vibrant color differentiation.
3. Electrochemical Anodization: Painting with Electricity
One of titanium’s most disruptive luxury features is its ability to take on vivid coloration without the use of fragile paints, platings, or enamels. Through electrochemical anodization, jewelers submerge the metal in an electrolytic bath and apply precise electrical currents.
Rather than adding a pigment, this process alters the thickness of the titanium’s natural oxide layer, changing how light refracts off the surface. Ateliers can consistently achieve fade-resistant, biocompatible hues ranging from deep electric blues and magentas to striking rainbow gradients.

4. Next-Gen Wearable Tech Integration
The booming smart jewelry sector demands materials that are bio-friendly, exceptionally durable, and featherlight. Aerospace-grade titanium has become the gold standard for this niche.
Market leaders like Ultrahuman utilize titanium chassis to house highly sensitive, medical-grade sensors. Because titanium acts as a rugged, hypoallergenic shield, it seamlessly protects internal components tracking Heart Rate Variability (HRV), skin temperature, and sleep cycles, all while offering the comfort of a traditional wedding band.
5. High-Jewelry’s “Stealth Wealth” Aesthetic
In the high-jewelry circuit, “heavy” no longer automatically equates to “valuable.” Elite international ateliers are embracing raw and black titanium as the ultimate canvas for haute joaillerie.

Weighing 45% lighter than stainless steel and a fraction of the weight of platinum, titanium allows designers to set massive, multi-carat precious gemstones into expansive designs without weighing down the wearer. Its deep, muted tones offer a stark, contemporary contrast to diamonds and colored gems, perfectly capturing the minimalist, “stealth wealth” aesthetic coveted by modern collectors.
