Research and development start-up, Glisten Technologies, has announced a breakthrough in diamond protection with a never-before-seen patented nanotechnology that maintains a diamond’s glittering light refraction by repelling the natural build-up of oils and proteins.

A known pain-point across the industry, diamonds attract oils and proteins which can lead to a cloudy appearance and diminished brilliance.

The cutting-edge nanotechnology presents a viable solution, providing an invisible and oil-repellent barrier – applied before the diamond is set – which prevents dirt, grime, and other substances from bonding to the surface of the diamond.

Jean Dousset, great-great-grandson of Louis Cartier and founder of Glisten Technologies, said: “Consumers want diamonds that stay as beautiful as the day they were purchased.

“This technology is the end of dirty diamonds and provides the perfect solution for jewellery manufacturers and retailers who want to provide their customers with the highest level of diamond protection.”

The nanotechnology is the result of many years of collaborative research and development between heritage luxury jewellers, scientists, and engineers.

Application of the patented nanotechnology works on both natural and lab-grown stones – ensuring that each retains its brilliant quality and beauty – and has no impact on the grading process.

According to research conducted by Glisten Technologies in partnership with the University of California, Los Angeles, protected diamonds have the potential to add more than $0.5b (£0.4b) of value to the jewellery industry in the next five years.

CEO of Glisten Technologies, Lindsey Saletta said: “Our mission is to provide diamond enthusiasts with the most advanced technology available to protect their precious stones.

“With a ‘Glistened’ diamond, jewellers can improve the consumer experience and offer them unparalleled protection, knowing that their diamond will remain pristine for years to come.”

Glisten Technologies is focused on preserving the integrity of diamonds – combining fine jewellery expertise, quality, and precious materials with molecular science.

Verified by accredited third-party labs, the technology has no impact on the visible light spectrum and no impact on the colour or clarity of the diamond.

The solution is affordable and scalable for the global diamond industry, which is projected to reach $139b (£112b) by 2030.

The nanotechnology is available now and subject to license agreement.
