Lab-Grown Diamonds Shake Up Jewelry Market

Gems News: The global diamond industry is undergoing a dramatic transformation as lab-grown diamonds rapidly gain ground among consumers. Once viewed as a niche alternative, these engineered stones are now competing directly with natural diamonds in both price and popularity. A new report by jewelry insurer BriteCo highlights how technological progress, shifting consumer attitudes, and post-pandemic economic pressures have combined to accelerate the rise of lab-grown diamonds across the market.

According to the report, improved manufacturing techniques and falling production costs have made lab-grown diamonds significantly more accessible to buyers. Over the past five years, the stones have moved from novelty items to mainstream jewelry choices. In fact, about 42 percent of all diamond jewelry sold recently contained lab-grown stones, including nearly 48 percent of engagement rings and 22 percent of other jewelry pieces. Midway through the industry’s rapid shift, this Gems News report notes that price differences remain one of the most powerful drivers behind the trend.

The gap between natural and lab-grown diamonds is striking. In 2025, the average price for a one-carat natural diamond stood around $4,200, typically ranging between $3,000 and $6,000 depending on quality and grading. By contrast, a one-carat lab-grown diamond often sells for about $1,000 or even less. That affordability has allowed buyers to consider larger stones or higher clarity levels that might otherwise be out of reach with natural diamonds.

Changing preferences have also influenced engagement-ring designs. With the lower cost of lab-grown diamonds, buyers increasingly opt for larger center stones and experiment with different shapes. The report indicates that the average size of a lab-grown center diamond in engagement rings grew dramatically from 1.31 carats in 2019 to about 2.45 carats in 2025. At the same time, classic round diamonds are losing ground to alternative cuts, with oval-shaped lab-grown diamonds emerging as the most popular style.

Industry observers believe the rapid expansion of lab-grown diamonds could reshape how diamonds are marketed and categorized in the years ahead. Some analysts expect natural diamond producers to respond with stronger branding campaigns highlighting rarity and tradition. Meanwhile, lab-grown diamonds may increasingly develop their own identity as a distinct category of jewelry rather than merely an alternative.

Another emerging trend involves fancy-colored lab-grown diamonds. Because producing vibrant colors in a laboratory environment is more feasible and affordable than finding them naturally, jewelers are exploring a wider palette of pinks, blues, and yellows. Advances in manufacturing technology could make these colorful stones even more accessible in the coming years.

The growing presence of lab-grown diamonds signals a pivotal moment for the jewelry industry. Consumers are balancing tradition, price, and sustainability concerns while exploring new styles and larger stones. As innovation continues and the market evolves, both natural and lab-grown diamonds are likely to coexist, each appealing to different buyer priorities and emotional connections. The competition between the two may ultimately expand the diamond market rather than shrink it, offering consumers more choices than ever before.
