The term "antique" refers to something that is more than 100 years old, and this includes jewellery that was created and used over several decades or eras, including the Georgian, Victorian, Edwardian, and Art Deco periods.
Like the old mine cut, diamonds cut into this shape possess a high crown, small table, and a large, flat culet. However, the old European cut has a circular girdle. With 58 facets, it is the predecessor of today's modern round brilliant cut. The Old European cut dates to the 1800s and was used mostly during the Victorian, Edwardian, and Art Nouveau eras.
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.
