Antique 1930s Art Deco .51 carat Old Mine Cut 18K filigree solitaire engagement ring

A pitch-perfect Art Deco engagement ring! This ring has hand-sawed filigree details and a juicy old mine cut feature stone. The 18K white gold mounting has engraved details on every millimeter, including bridal wreaths down the sides of the slim shank. A spacious, cage-like undergallery is wrapped in lush, leafy, foliate details. The head of the ring is utterly Art Deco: An Octagonal border with a round recess and north-south-east-west prongs hugging the diamond. We like the areas of smooth polish on this mounting (shoulders, around the diamond) as well as the busy hand-worked accents. The old mine cut diamond is a fine example of its style: one of a kind faceting, a tiny table, and a peekaboo culet. There is a nimble brilliance here and a the diamond invites you in like an old friend.
