Louis was joined by his two brothers Morris and Harry as the company grew and their designs became more and more popular, but Louis is credited with the design of the superior Kramer Jewelry.
Kramer made us of unique and rare specialty stones and beads in his designs. They also made a wide range of figural jewelry and whimsical pins, like many other designers of the times. During the 1950s and 60s, Kramer made jewelry for Christian Dior. These designs often had good quality rhinestones with large center focal stones. These Kramer/Dior pieces are very collectible and much sought after.
The 1950s marked the introduction of Kramer's "Golden Look." These pieces were simple designs which were made to go with the tailored look of the times. The quality was so good, it was hard to tell them from real gold. Later, during the 1960s, they introduced the "Diamond Look" which was meant to stimulate real diamonds.
The 1960s also saw the introduction of their ear covers. These ear covers had a curved wire which tucked behind the top part of the ear and the earring covered the whole ear and was worn with upset hairdos.
Since the company focused on glamorous jewelry, the natural look in jewelry which was introduced in the 1970s hit Kramer Jewelry hard and it closed its doors in the late 1970s.
