At the start of the 1940s the jewelry arts were interrupted by the onset of World War II. Precious metals, especially platinum, were rare and in some instances forbidden to be sold. Palladium was substituted for the platinum being used in the war effort. In order to eek the most out of the available gold, a low karat gold alloy was used with a higher copper percentage. This resulted in gold with a subtle but distinctive reddish tinge, indeed through the cunning use of alloys, gold appeared in multiple colors within a single piece. Gold was manipulated in various ways; woven, braided and coiled. Resilla, cannetille and lacy filigree patterns reappeared in jewelry. Various textures were juxtaposed within a design putting matte finish next to bright to accentuate the design. Gold became the quintessential jewelry metal of the 1940s and 50s.
