Belais Manufacturing Co., founded by David Belais (1863 – June 5, 1933):

Belais Manufacturing Co. was among the early manufacturers of white gold jewellery in the United States.  During the late 19th and early 20th century, they experimented with various alloys as a substitute for platinum in jewellery due to its expense and the onset of World War I.  As the war progressed, demand for platinum for military efforts increased. The costly metal was becoming harder and harder for jewellers to acquire, and eventually, in 1918, the government enforced a ban on all non-military use of platinum.

David Belais presented his final formula to the trade in 1917. A patent was applied for on October 5, 1918, and granted on February 10, 1920.

The formulation specified in Belais’ patent resulted in an 18 karat white gold alloy composed of gold, zinc, which thus avoided any problems with the platinum restrictions imposed by the war.

The advertising campaign for Belais white gold was incredibly successful and the term  ‘Belais’ became synonymous with white gold. In a November 22, 1922 issue of The Jewellers’ Circular their advertisement claimed they were the “Youngest in Style, Oldest in Skill.” Their slogan, “Belais Made Means Well Made”  successfully convince jewellery retailers and the jewellery buying public that Belais white gold was superior to all others. 

Belais and their advertisements made a lasting impact on the history of jewellery and importantly his white gold alloy.  The ad campaigns were so influential that in nearly every one of these ads, retailers sold original rings made using '18k Belais', as opposed to '18k white gold'.
