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.
In the early 1900s, diamond cutters began to experiment with new techniques. A breakthrough came in 1919 with the introduction of the round brilliant cut. Due to its ability to maximize fire and brilliance, the round brilliant cut has become the standard and most popular way to cut diamonds. Like the old European cut, a round brilliant cut diamond has a circular girdle and 58 facets. However, the round brilliant cut lacks a culet. The round brilliant cut became prevalent during the Art Deco and Retro periods.
Single Cut Diamond
A single cut diamond has a large table and an octagonal girdle. The culet, or bottom edge of the diamond, may be pointed or it may be flat. A single cut diamond usually has 18 facets. The single cut is an extremely old diamond cut dating to the 1300s.
Because of the softness of pure (24k), it is usually alloyed with base metals for use in jewelry, altering its hardness and ductility, melting point, color and other properties. Alloys with lower carat rating, typically 22k, 18k, 14k or 9k, contain higher percentages of copper or other base metals or silver or palladium in the alloy. Copper is the most commonly used base metal, yielding a redder color.
