Gems and Jewellery News: The Fall of a Sparkling Giant
Diamonds, long revered for their rarity, romance, and status, are facing one of the biggest upheavals in modern market history. Prices of both natural and lab-grown diamonds have fallen drastically over the past six months, rattling an industry built on the illusion of eternal value. Even with inflation pushing the cost of living higher, diamond prices are plummeting. While the drop has opened new opportunities for consumers seeking larger stones at lower prices, the industry is grappling with deep structural changes that could permanently redefine the concept of luxury.

In this Gems and Jewellery News report, analysts cite several interwoven causes for the crash: a cooling luxury sector, rapid innovation in lab-grown production, shifting consumer behaviors, and growing resistance toward traditional diamond narratives.
What’s Behind the Price Collapse
Rise of Lab-Grown Alternatives
Once a novelty, lab-grown diamonds are now a force reshaping the global gems market. Their quality is often indistinguishable from natural diamonds, but their cost is dramatically lower. Recent innovations allow diamonds to be grown in plasma chambers within hours—compared to the billions of years it takes nature. As a result, supply is skyrocketing, particularly from mass producers in India and China.
Lab-grown gems now account for 45% of the bridal jewelry sector and have pushed the average retail price of a one-carat lab-grown diamond down to just $265 by mid-2025, a staggering drop from $3,410 in 2020.
A Shrinking Luxury Market
After the post-COVID “revenge spending” wave faded, the luxury market began to tighten. Inflation, geopolitical instability, and fewer weddings—especially in key markets like China—have contributed to softening demand. De Beers reported a $2 billion diamond stockpile at the start of 2024, forcing the company to slash production by 20%. Anglo American, De Beers’ parent company, has since put the iconic brand up for sale.
Shifting Values and Tastes
Younger consumers, particularly millennials and Gen Z, are gravitating toward ethical sourcing, budget-conscious purchases, and experiences over traditional status symbols. Lab-grown diamonds fit the bill—traceable, sustainable, and less burdened by the historical controversies that haunt mined diamonds.
Natural Diamonds Still Hold Their Ground
Despite the storm, there remains a segment of consumers loyal to natural diamonds. Some jewelers, like Geoffrey Farrow of Raphael in Hatton Garden, continue to resist lab-grown sales. “They are synthetic,” he argues. “There’s no history to it. Quality and heritage matter more than size.”
Prices for mined diamonds haven’t escaped the fall either. Industry expert Paul Zimnisky says rough natural diamond prices have dropped by 36% since their 2022 peak. Retail prices followed suit, with one-carat natural diamonds falling from $6,819 in May 2022 to $2897 in mid-2025.
Size Over Sentiment
While the romance may be fading, consumers are still spending—just differently. Buyers with budgets between $5,000 and $8,000 are now opting for stones two to three times larger than what they would have purchased a decade ago, especially in the lab-grown category. Three to five-carat rings are no longer out of reach for the average engagement shopper.
A Market at a Crossroads
The diamond trade has survived massive shocks before—from Brazil’s 18th-century diamond rush to South Africa’s 1867 discoveries. In each instance, clever marketing and new consumer classes helped stabilize the market. More recently, the surge in Chinese engagement ring culture propped up demand.
But experts like jewelry historian Jack Ogden warn that the diamond industry’s core premise—value sustained by perception—may no longer hold in an era of rising transparency and environmental awareness. The final frontier of potential growth, Africa, may remain elusive due to lingering ethical concerns surrounding conflict diamonds.
Reinventing the Narrative
Major players are not giving up without a fight. De Beers is ramping up campaigns to reinforce the emotional and symbolic superiority of natural stones. Some believe celebrity endorsements and red-carpet glamour at events like the Oscars may gradually sway public opinion back toward mined gems. However, with production technology advancing and consumer sentiment evolving rapidly, the battle for market dominance is far from over.
If diamonds are forever, the same might not be true for their traditional pricing power. As affordability opens the floodgates for larger stones and synthetic brilliance, only time will tell if natural diamonds can reclaim their sparkle—or if they’ll become relics of a bygone era.
The global diamond industry must adapt or risk irrelevance. With lab-grown options flooding the market, shrinking wedding rates, and ethical consciousness on the rise, old marketing tricks may no longer be enough to sustain high values.
While some consumers remain loyal to natural gems for their perceived authenticity and rarity, the tide is clearly turning. If sentiment and desire drive demand, the industry may have to reinvent desire itself.
