From Alixandra Collections comes this eponymous ring, set with diamonds in … mystery metal. That’s right, it isn’t specified on the web site. Nor is the total diamond weight. The site notes merely, Pave Diamond Horizontal Oval Ring; Art Deco Backing with Ribbed Ring Base; Size 8.”
The Art Deco backing looks like a honeycomb effect, almost Moorish; pretty but not sure it qualifies as deco.
This mystery piece sells for USD $975.
