Astrea London records 100% sales increase to £1.5m in first half of 2026

Luxury lab-grown diamond brand Astrea London has achieved a 100% sales increase to £1.5m during the first half of 2026, building on the momentum generated by its £4m fundraising round last year and accelerating its international expansion plans.

The company, which was valued at £40m following the funding round completed in mid-2025, closed last year with revenues exceeding £1m. It now expects annual turnover to surpass £5m by the end of next year, with a longer-term ambition of exceeding £10m by 2030.

The growth comes as the global lab-grown diamond market continues to expand, with Astrea London forecasting it will increase from $30bn (approximately £22.4bn) to $50bn (approximately £37.3bn) over the next decade. Astrea London has also benefited from growing demand for high-value pieces, recently selling its French Riviera Necklace for around £240,000. The necklace features a 174-carat lab-grown diamond alongside 152 carats of freshwater pearls.

Alongside its commercial growth, the company has continued to broaden its product offering and international presence. It recently launched its first men’s collection in collaboration with brand ambassador Maro Itoje and is preparing a second collection with global creative director Sarah Jessica Parker.

The expansion also extends to retail, with Astrea London recently opening a boutique at the Mandarin Oriental Hotel Lutetia in Paris ahead of the launch of a flagship store in New York, which is scheduled to open during the final quarter of 2026.

Nathalie Morrison, founder and chief executive, said: “We have had a record first six months and are set to more than double sales this year. In the two years since I founded Astrea we have developed into a global brand and the leading luxury purveyor of lab diamonds.

“The lab diamond market is still in its infancy and I’m excited for the potential across all levels: New stores in many capital cities, new brand ambassadors, unique collections and evolution of men’s diamonds. The UAE and GCC continue to be a key focus of our long-term expansion and has been a key factor of our success to date.”
