Antique Art Deco 1930s 18K .52 carat SI1/H Old Mine Cut diamond engagement ring

A ruggedly beautiful old mine cut diamond tucked into an Art Deco filigree mounting. The setting here is noteworthy: 18K white gold and hand-sawn and engraved with heaps of detail up the shoulders and around the gallery. The .52 carat old miner diamond is set in an octagonal head. This stone has a very large culet (visible as a dark contrast point at the bottom of the diamond!) and the funkiest table and crown we have seen in a while. The diamond pre-dates the setting but we love the partnership here: a quirky, assymetyrical stone in a linear, formulaic mounting. A serenade to 19th and 20th century sensibilities.

Measurements: Size 7 US, 2.9 grams. This ring may be sized in the 5-8 US range for $75.
Diamond details: (1) Old Mine Cut diamond, .52 carat, SI1/H, (4.60 x 5.10/2.80mm)
Era: 1920s-1930s
