A singular blue diamond is the centrepiece of this diamond ring, its extraordinary colour caused by the presence of boron in the environment in which it was created. It is radiant-cut for maximum Brilliance, and neighboured here by a pair of expertly matched tapered baguette-cut diamonds, their classic forms creating an architectural feel. The result is a modern and elegant piece, in an exceptionally rare natural colour. This collection of diamonds is prong-set on a platinum band. Each diamond in this piece, as in all De Beers designs, is responsibly sourced, selected by eye and hand-set by our team of experts.
