Diamond | NMNH G10600 | 4.58 ct |
This platinum and diamond ring was a bequest to the National Gem Collection in 2007 by Margaret McCormack Sokol. The ring features an emerald-cut diamond that weighs 4.58 carats, flanked by two tapered baguette-cut diamonds. The emerald-cut, a type of step-cut, was given the name because it is a common cut for emeralds. It has a square or rectangular outline with rectilinear facets arranged parallel to the girdle of the stone, with truncated corners creating an octagonal outline. The facets are arranged in a step-like fashion and produce a “hall of mirrors” effect within the diamond. Even though emerald-cut diamonds do not have the brilliance of round brilliant cut diamonds, they are usually very high in clarity as the inclusions can be seen quite easily. Emerald-cut diamonds were very popular during the Art Deco Period when geometric cuts for gemstones complimented the symmetry and streamlined look of the jewelry. Emerald-cut diamonds are classic and timeless in design and are commonly seen accented with baguette cut diamonds. This custom-made ring is a “treasure from the vault” at the National Museum of Natural History.
