In November 2023, over 3700 laboratory-grown diamonds weighing 10ct or more were listed for sale on wholesale platforms. Have we hit over 4000?

YES! Two months after the last update and the available 10 carat-ers have increased to 4655. This is a 24% increase in this short time period. We may be just a month away from seeing over 5000 for sale on the market.

The largest stone for sale this month was a 40.50ct oval G/VS1 grown through CVD synthesis and priced at $4134.00/ct ($167,435.00 wholesale).

The cheapest 10ct stones start from $221.00/ct ($2215.00 wholesale) for a 10.02ct emerald cut H/SI1. For different shape and better quality stones (F+/VS+), these typically start from around $550/ct ($5500.00).

20ct stones start at $1525.00/ct (H/VS2 emerald cut) and the majority have wholesale prices between $20,000.00 - $50,000.00.

Date of figures: 26th Jan 2024
