Eisenberg, one of the most respected names in costume jewelry, was started in 1914. The Company originally produced clothing at its beginning in 1914, attaching pins to their creations. These pins become so popular that Eisenberg began production of jewelry exclusively and abandoned its clothing line. Eisenberg pieces were impressive, usually big, bold and beautiful.
During World War II, sterling silver settings were replaced with rhodium plating. Rhodium maintains its beauty and is impervious to most tarnish conditions, so jewelry pieces were well preserved over the years, despite use. Swarovski and Czech crystals were the stones exclusively used in Eisenberg pieces.
Many of the larger pins and brooches used a minimal amount of glue and each individual stone was hand-set into tiny prongs, a time-consuming process. Foil backings further enhanced the stones’ ability to reflect the light.

In 1977, Eisenberg became a part of Berns-Friedman.
Eisenberg did not always sign their pieces, but some known Eisenberg signatures are as follows: Eisenberg Original – used from 1935 to 1945; Script letter E used alone or with Originals – 1940s; Script letter E used on Sterling – early- to mid-1940s; Hallmarked STERLING in conjunction with the block EISENBERG signature – 1943 to 1948; Block EISENBERG and block E – c. 1945 to 1950; EISENBERG on marker in small block letters – c. 1950’s; Script Eisenberg – registered in 1981, used as early as 1935; Eisenberg Ice in block letters – used as early as 1941 till 1958; Script Eisenberg Ice – use began in 1970’s; and jewelry manufactured between 1958 and 1970 was not usually marked.
The classic styling and timeless beauty of the older Eisenberg brooches have inspired the company to resurrect designs that are 25 or more years old. The earlier pieces have become collectors’ items whose current values can range from $200 to thousands of dollars. Eisenberg is still making jewelry today, and all brooches and most necklaces currently in production are stamped with ‘Eisenberg Ice’ and should eventually have collectors’ value.
