Vintage 1940s KREMENTZ Goldtone ~ Fine Quality Tiger Eye Gemstone Rectangle Cufflinks. Comes in a grey velvet Krementz Box. The rectangle shaped cufflinks are 3/4" x 5/8" with an oval Tiger's Eye gemstone that measures 11 mm long by 7 mm wide by about 2-3 mm high (hard to tell in the bezel). The gemstone is set in a bezel with a beaded border. The only marks on this piece is the stamp KREMENTZ in all caps with no copyright or trademark symbol, which means they could have been made at any time before 1954, when jewelers began using copyright or trademark symbols. The gemstone is very beautiful with no scratches.
