White gold Square ring with Princess diamond, brilliant-cut diamond halo and shank

At the center a square diamond, closed in a setting that takes it on all four sides. Around it runs a square frame of brilliants, four to a side, with four ribs of metal that start from the corners of the setting and reach the outer corners. The setting stands raised above the shank, and in profile the space under the square stays empty; the shank carries five brilliants on each side, set into the thread of the metal, and thins as it goes down towards the bottom.

The square at the center is a Princess cut of eleven points of a carat, color F and clarity VVS: F is the last grade in the colorless band, VVS means inclusions that are found only at ten magnifications. The twenty-six brilliants of the surround and the shank come to twenty-two points in all, less than a point each: stones you count, not stones you weigh. Twenty-seven diamonds in all, on three grams thirty of eighteen-carat white gold.
