Cartier Gold Desk Timepiece with Lapis Lazuli and Jade

• Art Deco Period - The Art Deco period was a cultural movement that emerged in the 1920s and 1930s, and was characterized by its emphasis on modernism, luxury, and elegance. The name "Art Deco" comes from the Exposition Internationale des Arts Décoratifs et Industriels Modernes, a large exhibition held in Paris in 1925 that showcased the latest trends in decorative arts.
  
  Art Deco was a reaction against the ornate and elaborate styles of the previous era, and reflected a new modern sensibility. It was characterized by streamlined, geometric shapes, bright colours, and the use of new materials such as chrome, glass, and Bakelite. Art Deco designers sought to create a sense of luxury and sophistication, often incorporating expensive materials such as ivory, marble, and rare woods.
  
  Art Deco had a significant impact on a wide range of artistic fields, including architecture, fashion, graphic design, and interior design. Some of the most iconic examples of Art Deco architecture include the Empire State Building in New York City, the Hoover Building in London, and the Palais de Chaillot in Paris.
  
  The Art Deco period came to an end in the 1940s, as World War II and changing cultural trends led to a shift in artistic styles. However, Art Deco remains an important influence on design and art, and continues to be celebrated for its modernist sensibility and glamorous aesthetic.
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
• Bezel - On a clock or watch, the bezel is the metal frame into which the watch or clock glass is fitted. In clocks, the bezel may include a hinge and a flange, in effect a door to the face of the clock. In jewellery the bezel is a band of metal with a projecting lip that holds the gemstone in its setting.
• Lapis Lazuli - Lapis lazuli is a semi-precious deep blue coloured stone, sometimes with gold inclusions, that has been used for thousands of years for jewellery, decorative items and decoration.
  
  It is mined in Afghanistan, Siberia, Chile, USA and Burma. The mines in north-eastern Afghanistan are the largest source of lapis lazuli, and have been operating for over 6,000 years.
  
  They were the source of the stone for the ancient Egyptian, Greek and Roman civilsations.
• Movement - The technical name for the workings of a clock or watch, and does not include the dial or case.
• Timepiece - In today's usage, the word "clock" is the name given to any instrument used for measuring time, but the word clock is derived from the Celtic word meaning "bell", and traditionally a clock without a bell or chime was known as a timepiece.
