Eisenberg Ice Art Deco Antique Emerald Cut Glass Engagement Ring Sz 7

Due to its age there is some yellowing of the glass as shown in the photos but otherwise this is a very impressive and gorgeous ring, very high quality and rare to find. I believe it is art deco period due to its design and the fact they had yet to be granted a patent (vs. their 30s/40s stamps). Size 7, emerald cut and signed Eisenberg Ice pat. pend. on the interior
