US retail: approximate market ranges for E/VS2, round brilliant at major online retailers. Natural diamond prices: approximate US retail estimates, wide variance by retailer and individual stone. Draco Diamond: May 2026 catalog in CAD. IGI certified, E–F color, VS+ clarity. Price gap calculated against approximate natural diamond retail midpoint. Lab grown prices vary significantly by retailer, cut quality, and certification. Exchange rate: 1 CAD = 0.73 USD.
Edahn Golan documented that US specialty jewelers grew gross margins on lab diamonds from 48.9% in 2020 to approximately 74% by 2025. Lab diamond prices fell at the market level, but legacy retailers absorbed much of that decline as margin rather than passing it to buyers. Canadian buyers shopping from US retailers pay that margin plus currency conversion. A Canadian direct to consumer retailer pricing in CAD and sourcing directly reflects the actual market price.
"The lab diamond price collapse was not a promotion. It was a structural market shift driven by manufacturing scale that no single company can reverse."

Section 04 · The Natural GapThe Lab vs Natural Price Gap in 2026
The price gap between lab grown and natural diamonds widens non linearly as carat weight increases. A 1ct natural diamond is approximately 7 to 9 times more expensive than its lab grown equivalent at retail. A 5ct natural diamond is approximately 15 times more expensive. A 10ct natural diamond can be 20 times more expensive. This is because large natural diamonds are increasingly rare and command scarcity premiums that lab grown diamonds do not.
Below 1ct, lab is roughly 8x cheaper. Above 5ct, lab is roughly 20x cheaper. The bigger the stone you want, the more lab grown wins.
Natural diamonds above 3 carats are geologically rare. Each large stone is unique and supply is inelastic. Lab grown diamonds above 3 carats can be produced at scale with similar economics to smaller stones. As carat weight increases, natural diamond prices rise exponentially while lab grown prices increase roughly linearly. This is why a 10ct natural diamond can cost 20 times more than its lab grown equivalent while a 1ct natural is only 8 to 10 times more expensive.
Section 05 · Market StructureWhy Lab Grown Diamond Prices Are Low in 2026
Lab grown diamond prices fell 74% from 2020 to 2025, per Edahn Golan Diamond Research. The cause was a 300% expansion in global CVD manufacturing capacity across hundreds of independent producers across global manufacturing hubs. No single company controls supply. The knowledge, equipment, and infrastructure are distributed. This is structurally different from natural diamond mining, where De Beers and a small number of producers historically controlled supply and therefore price.
The annual rate of price decline decelerated to high single digits entering 2026, per Edahn Golan. Prices are stabilizing at historically low levels, not recovering toward 2020 pricing. By 2025, 85.9% of lab diamonds sold were colorless, per BriteCo's November 2025 report, because the premium between colorless and near colorless grades compressed as prices fell. Buyers are now accessing top tier color and clarity at prices that would have been impossible five years ago.

The price gap widens at higher carat weights because large natural diamonds are increasingly rare while large lab grown diamonds can be produced at scale.
Lab grown diamond prices fell 74% from 2020 to 2025, driven by a 300% expansion in global CVD manufacturing capacity across global manufacturing hubs, per Edahn Golan Diamond Research. No single company controls supply. Prices are now stabilizing at historically low levels. The annual rate of decline decelerated to high single digits entering 2026, meaning prices are finding a floor rather than continuing to fall at 2024 rates.
The structural forces keeping lab grown diamond prices low remain intact. Global CVD manufacturing capacity is distributed across hundreds of independent producers across global manufacturing hubs who operate without coordination. No single company or policy change can reverse the fundamental economics. Edahn Golan Diamond Research estimates the annual rate of price decline has decelerated to high single digits in 2026, suggesting prices are stabilizing at current levels rather than recovering toward 2020 prices.
Most lab diamond price data is published in USD by US based retailers. Canadian buyers face currency conversion on top of US retailer margins. Edahn Golan documented that US specialty jewelers grew gross margins on lab diamonds from 48.9% to 74% between 2020 and 2025, absorbing the price decline as margin rather than passing it to buyers. A Canadian direct to consumer retailer pricing in CAD and sourcing directly reflects the actual market price without that additional margin layer.
