Rectangular OMC Diamond Buttercup Ring in 14k Gold
An antique engagement ring, set with a rectangular old mine cut diamond. The diamond has a large, open, mirror-like table, and is held aloft in a six-prong, white gold, buttercup setting. The ruffled buttercup is set into the ring's cathedral shoulders. The ring shank is flat and slender, with a subtle pair of notches decorating it below the shoulder. Metal is 14k gold. This Edwardian-era setting was made to hold this older diamond.

Ring head measures approx 9.5 x 8.9 mm. Ring shank measures approx 1.8 mm at the back. Diamond weight is 0.58 carats (weighed loose), and measures approx 5.76 x 4.59 x 1.91 mm. Diamond is SI1 / I-J.
This diamond was cut with a large, open table, but its pavilion is quite shallow; for this reason it appears larger, in wear, than contemporary cuts of comparable carat weight.
