Better Star Unveils 2025 Fancy Color Collection at Hong Kong International Jewellery Show

The report, compiled from production data across six major diamond-growing nations, signals a dramatic acceleration in lab-grown diamond adoption that began in 2021 and has continued without interruption. Total rough production grew 22% year-on-year, with polished diamond volumes expanding even faster as downstream processing efficiency improved significantly across all major producing regions.

China's dominance in the sector reflects decades of investment in semiconductor-grade CVD reactor technology, which has been adapted with remarkable success to diamond growth applications. The country's industrial base — spanning over 300 registered diamond cultivation enterprises in Henan Province alone — now produces the majority of the world's supply at cost levels that continue to decline year over year.

The Consumer Shift Accelerates

Alongside production growth, consumer awareness and acceptance of lab-grown diamonds have reached new highs globally. Independent surveys conducted across North America, Europe, and Asia Pacific show that awareness among fine jewelry buyers now exceeds 78%, up from less than 40% in 2021. More significantly, purchase intent among aware consumers has grown from 32% to 61% over the same period — a shift that represents a fundamental change in how buyers perceive value in the diamond category.

"The tipping point has passed. Lab-grown diamonds are no longer a niche category — they are becoming the default choice for value-conscious consumers who refuse to compromise on quality or ethics."

The engagement ring segment has seen the most dramatic shift. Industry data from the United States, the world's largest bridal jewelry market, shows lab-grown diamonds capturing an estimated 42% of new engagement ring center stone sales by unit volume in the first half of 2025 — compared to just 6% in 2020. This trajectory shows no signs of slowing.

Price Dynamics and Market Maturity

The rapid expansion in supply has been accompanied by continued price normalization. Average retail prices for a 1-carat D/VS1 round brilliant lab-grown diamond now sit approximately 75–80% below equivalent natural diamond prices — a gap that has stabilized compared to the more dramatic declines seen in 2022–2023. This stability is increasingly viewed as a sign of market maturity rather than further disruption.

Industry analysts suggest this price stabilization reflects a maturing market where production costs have largely plateaued and demand is growing rapidly enough to absorb incremental supply growth. The era of steep annual price declines may be giving way to a more stable pricing environment — one that supports healthier retailer margins and more predictable supply chain planning for all participants.
