Between the 1910s and 1950s, jewellery design remained original and glamorous despite being impacted by cycles of boom, depression, and war. While exotic creations influenced by the Near and Far East revealed that jewellery fashions were genuinely global, sharp, geometric patterns hailed the machine era. Now that New York was on par with Paris as a fashion hub, European jewellery companies could anticipate selling to and purchasing from the Indian subcontinent. Art Deco jewellery is distinguished by dense clusters of gemstones. Because it was less expensive than platinum starting around 1933, gold started to reappear in fashion. Jewelry design attracted artists and designers from several disciplines. The new paths jewellery would go in are hinted at in their work.
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.
