Lab-Grown Diamond Prices Plunge as Market Forecasts 60% Growth by 2032

GemGuide reports "another steep fall in lab-grown diamond (LGD) prices," writing in the March/April 2026 issue under Richard Drucker, GIA GG, FGA (Hon.), file date 2026-02-25, and begins an example with the fragment "A 1.00‑carat LG" in the published excerpt. That immediate price weakness sits beside two very different long-range pictures: Coherent Market Insights, as quoted on Caratx, projects the global lab-grown diamond market to rise from $27.7 billion in 2025 to $44.5 billion by 2032, a "monumental 60% increase in just seven years" with a 7% compound annual growth rate.

Caratx frames the CMI analysis with broad cultural language and concludes that "The $44.5 billion forecast is more than a market projection; it is a testament to a permanent shift in consciousness. The lab-grown diamond is a disruptive force that has successfully carved out its own legitimate and massive category by aligning with contemporary values without compromising on beauty or quality." The CMI figures on Caratx therefore pair a concrete dollar path - $27.7 billion to $44.5 billion - with a thesis that technological and consumer shifts will entrench lab-grown stones in the luxury market.

Statista offers a contrasting numeric path. In a Dec 17, 2025 page attributed to René Muschter, Statista lists a "Lab-grown diamonds market value forecast 2032 : 59.5bn USD" and states that the lab-grown sector's share of the total diamond market is expected to amount to over 21 percent in 2025, with a page metadata figure of 21.3 percent for 2025. Statista also breaks production-method outcomes into two clear categories, noting "There are two main methods for producing lab-grown diamonds: high-pressure, high-temperature (HPHT), and chemical vapor deposition (CVD)," and forecasts that "By 2030, it is forecast that the market revenue of lab-grown diamonds produced with the CVD method will amount to 30.1 billion U.S. dollars."

Statista flags a supply-side technical distinction that maps to value: "The HPHT process is less popular than diamonds produced with the CVD method however, because it typically produces yellow or brown diamonds of lower economic value." Statista’s page carries its standard caution: "This text provides general information. Statista assumes no liability for the information given being complete or correct. Due to varying update cycles, statistics can display more up-to-date data than referenced in the text."

The juxtaposition is stark. GemGuide documents current price erosion in specific retail or trade terms, while CMI and Statista offer divergent growth endpoints for 2032 - $44.5 billion versus $59.5 billion - and Statista quantifies the rise of CVD to $30.1 billion by 2030. The supplied material does not reconcile the two 2032 totals or detail whether forecasts measure retail value, wholesale shipments, or include industrial stones, but the numbers themselves imply very different assumptions about pricing, volume growth, and segmentation.

For buyers and makers, the immediate takeaway is practical: price indices and production-method trends matter. GemGuide’s report of a fresh price decline and Statista’s projection that CVD will dominate revenue both signal that the market is shifting beneath traditional retail pricing even as forecasters expect sizable market expansion through 2032.
