Vintage 14K White Gold Mine Cut and Old European Cut Natural Diamond Ring

c1940 but I think the main three diamonds are probably older and this piece could be a creation in the 1940's of older family diamonds. 

The ring is stamped 14k and verified. Unusual style with a marquis center with milgrain edging that's slanted and set with three natural diamonds. The center diamond weighs approx. .50 ct, faint, large open culet and looks closer to a mine cut than an Old European cut. One old European cut side diamond weighs approx. .35 ct, faint and the other is approx. .35 ct, near colorless. Center diamond is an I clarity with surface reaching inclusions, the other two look clean under loupe--VS-SI.

The shoulders have 8 round cut accent diamonds set in ribbon motifs with milgrain edging, approx. .20 ctw. 1.4 cts estimated total diamond weight

Front measures 5/8" top to bottom. 

3.8 grams
