Edahn Golan, who has 20 years of experience as a diamond industry analyst, provides insight into how the lab-grown diamond market continues to decline.

This has been an ongoing trend since they were first introduced to the market eight years ago.
These declines have persisted into the first quarter of 2025. The average trading wholesale price of one-three carat round-shaped lab-grown diamonds decreased by 8.9% from the fourth quarter of 2024, according to the LGD Wholesale Price List for the quarter ending March 2025.
The price list is based on Mumbai wholesale trading prices of single-stone parcels, IGI-certified lab-grown diamonds in nice makes.
In the past few years, the decline of lab-grown wholesale prices has slowed down and is moderating. Another trend is price compression, where the price difference between sizes is collapsing.
In March, the average wholesale price difference between a one-carat and a two-carat lab-grown diamond was about 10%.
While the wholesale price list reflects wholesale market trading prices, they do not represent retailers’ costs.
The current price trends of declines, deceleration, and compression are expected to continue in the near future.
The one area of uncertainty is what impact US tariffs will have on the market. Although they should not have a major impact on trade between the UK and India, a price decline is still a possibility.
