An exceptionally distinctive BRAND NEW custom-made platinum natural diamond solitaire engagement ring, showcasing a rare and sophisticated 0.81 carat Fancy Dark Greenish Gray round brilliant-cut diamond. With its unusual natural-looking depth of colour, substantial platinum construction, and refined custom setting, this is an engagement ring for someone seeking something genuinely different from a traditional colourless diamond solitaire.
The ring has been wax cast, hand assembled and hand finished in platinum, with a substantial yet elegant profile and beautifully polished finish. Its custom mounting features a tapered “V”-shaped gallery with a solid underside, creating a strong architectural presentation for the centre diamond while allowing the stone to remain the unmistakable focal point.
Gracefully upswept rounded rectangular shoulders flow toward the central setting, producing a clean and contemporary silhouette. The interior of the shank is fashioned with a rounded rectangular comfort-fit curve, making the ring pleasing to wear despite the substantial weight and quality of its platinum construction.
At the centre is a 0.81 carat round brilliant-cut diamond measuring approximately 5.85 mm x 5.86 mm x 3.72 mm.
The diamond is accompanied by GIA Diamond Report No. 5151395245, dated June 19, 2007, and has been graded an exceptionally unusual Fancy Dark Greenish Gray colour with SI1 clarity.
Unlike the conventional white diamond solitaire, this stone possesses a dramatic, sophisticated character. Its deep gray body colour is complemented by subtle greenish undertones, while the round brilliant faceting creates flashes of light and contrast across the surface of the stone. The result is an understated but highly distinctive diamond with an elegant, almost mysterious appearance.
The diamond has also received Excellent Polish and Very Good Symmetry grades from GIA, supporting its beautifully finished appearance.
