Unique engagement ring in an Art Nouveau style consisting of a marquise diamond and red gemstones, where the main attraction is the bezel set marquise diamond in 18K white gold. The old cut marquise diamond is measuring approximately 7.5mm x 3.5mm or 0.33 carats with three additional smaller single cut diamonds for an additional 0.12carats for a total diamond weight of approximately 0.45 carats! The marquise diamond does show a hint of color as many vintage diamonds of the era did, which some may call a cinnamon champagne diamond, estimated in the L-M color/SI2 clarity range There are also seven red colored stones which tested as spinel on a Presidium gem tester (although a few appear dichroic and are possibly melee rubies) that measure two to seven points for a total of 0.34 carats. The substantial setting measures 25 x 18mm with a 6mm rise off the finger and the 14K rosey hued yellow gold shoulder width is 3.75mm tapering to 2mm and can be sized by a trusted jeweler. There are also lovely orange blossom details on the setting which gives it that feminine touch of decorative detail that adds such wonderful character to these fabulous vintage treasures!
