This fine collection of Wachenheimer Brothers jewelry includes sterling silver Diamonbar bracelets, perhaps their best-known product line, and late-1920s earrings. These earrings are from the later Wachenheimer Real Stone Jewelry line, which features semi-precious stones mounted in sterling silver. The Diamonbar trademark was first used as the name of the company’s sterling silver bar pin, which was introduced in 1916 in a series of ads in Vogue magazine. Two utility patents granted to Harry Wachenheimer pertain to the construction of the company’s bracelets. In operation from 1905 to 1934, this highly-regarded company went out of business during the Great Depression.
