Size 5 New / Old stock costume jewelry rings

This purchase is for 2 Size 5 costume jewelry rings. Both are from a business that closed in the 1990s and have been in storage since. They are new with original store tags on them. The one on the left (wider style) has some flaw marks on the back of the band where it appears the electroplating did not adhere well, it is just a rough spot. It is stamped 18k HGE. The one on the right has no flaws - a perfect faux wedding ring. Stone is Cubic Zirconia and band is stamped 14K HGE.
