De Beers Diamond, .40 cts., F/G, VS1-VVS Platinum Ring.
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. This very fine diamond is estimated to weigh .40 cts., is well cut with fine symmetry. 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. Today, a preponderance of jewelry is machine made in large factories around the world with abundant and obvious suspicions as to its enduring qualities using not only inferior stones, but also man made stones and treated stones utilizing artificial substances. Alternatively, this fine diamond ring by a De Beers is an excellent example of a solitaire ring - wonderful hand craftsmanship, an important diamond House...
