Art Deco Engagement 1920-45
With the advent of the gas torch and gas dye-press, the Art Deco era became time for designers and artisans experimentation. The roaring twenties are represented by filigree, filigree and more filigree. These rings were made by either cutting/punching a sheet of noble metal with a dye and press, and then a jeweler would form it into a ring and set it with a diamond. Sadly, with the great depression, many of these rings sat in jeweler's cases with no customer to buy them at the price they had them listed at, due to their larger diamonds. Stealthily, those jewelers added small plates surrounding a smaller diamond and set them in place of the larger stones, making it possible to lower the cost on those rings to accommodate their depressed market. In the 1930's things became more rounded and bulbous but the use of filigree was popular, as well as more saddle-styled, multi-stone rings. Most Art Deco engagement rings were not worn with bands except by collectors and an elite few who probably stacked multiple rings on their finger. This era also used many type of synthetic stones, and with engagement, specifically synthetic sapphires which are often used to flank and frame a center diamond.
