The emerald cut - originally conceived for the green gemstone - is a long step cut with beveled corners. Using it for diamonds became popular in the early years of Art Deco; it was well-suited to an aesthetic period marked by its use of clean lines and geometric shapes. This platinum engagement ring was made at the tail end of the Deco era and is engraved inside "T.J.C. - E.M.G. 11-15-45." It comes with an EGL diamond certificate and appraisal for the center stone.
