Eisenberg Vintage Brooch Earring Set

This aurora borealis crystal rhinestone set is absolutely stunning! In excellent vintage condition set in gold tone. Unsigned. I have been told that a vintage jewelry appraiser confirms that this is an Eisenberg. Research tells me that Eisenberg stopped stamping most pieces made between 1952-1970 The quality is consistent and excellent. Measurement is approximate. The clip earrings could be clipped on to a shirt collar with the brooch pinned at the top button for a modern twist.
