Denis Bellessort, the founder of Bonds of Union in London, celebrated the launch of a new collection by flying a 10 ct. (£1million) diamond above Holland Park in west London. 

The new collection, called Diamonds, was designed to highlight the luminescence of the stones and showcase each diamond as a “star in the sky,” Bellessort tells JCK.

And so in celebration, he wanted to fly an actual diamond. The stone was attached to a remote-controlled hexacopter (a six-bladed mini-helicopter) and rigged with lights for maximum shine visibility. 

“Our enquiries with focus groups in London and Paris show that ladies and girls very much love our diamond luminescence and scintillations, and men are fascinated with the scientific side as much as they like the aesthetics of the pieces,” he explains.

The flight involved much research and trial and error, Bellessort says. “We researched a way to create unique scintillations. We researched the light of diamonds when illuminated in the sky,” he says. “We have light sources attached to a rig close to the diamonds and other sources of lights,” he says, but he would not elaborate, saying the designs are with a patent attorney.

He hopes to give repeat performances in Paris, near the Eiffel Tower, and in New York City’s Central Park.
