The collection consists of six rings, designed by the jeweller and handcrafted in Britain, with each ring featuring a diamond with a side of colour.
It also features a variety of shapes and sizes of old-cut diamonds, all set with coloured gemstone shoulders with specially cut aquamarines, sapphires or emeralds.
Guy Burton, director, Hancocks London, said: “This collection evolved from discussions we had about different ways to complement and enhance our beautiful old cut diamond solitaire rings.
“Cutting stones to fit exactly into a design like this is known as calibre cut. Each one of these coloured gems has been designed and cut by hand so that they precisely fit into the shoulders of the band of each ring. The attention to detail this affords is reflected in the beauty of these jewels.”
He added: “Our beautiful antique diamonds don’t necessarily need any embellishment but sometimes it’s good to add a splash of colour, subtle or otherwise. We hope these rings will appeal to people who like their classics with a little contemporary twist.”
