Located in Aspen, CO
De Beers diamond solitaire platinum ring. The center prong set square cut diamond is estimated by our internal gemologist to be very white - F/G (colorless to near colorless), and very very slightly included.

Set in platinum and signed on the interior this ring (De Beers number, De Beer's hallmark as well as their hallmark of setting a small diamond in the interior of the shank, and also this ring bears the mark for platinum). This ring is in fine condition and is accompanied by its original De Beers box. This ring is now a size 6.25 and can easily be resized. Our model has a medium to large hand size.
