Kramer of New York is one of those names dealers run across pretty frequently when sourcing costume jewelry. That usually means a company saw a good amount of success back when the jewelry was newly made. Nevertheless, it's not a brand most fervent collectors get overly excited about. It might be on the uptick, though, since I've noticed pieces lingering in online shops being snatched up these days indicating a growing base of fans out there in jewelry land.
My personal opinion of Kramer jewelry? It's always been pretty high. Some of the lines this company marketed in the 1950s are over-the-top gorgeous and many are undervalued today
