• Mother-Of-Pearl - Mother-of-pearl, technical name "nacre", is the inner layer of a sea shell. The iridescent colours and strength of this material were widely used in the nineteenth century as an inlay in jewellery, furniture, (especially papier mache furniture) and musical instruments.
  
  In the early 1900s it was used to make pearl buttons. Mother-of-pearl is a soft material that is easily cut or engraved.
  
  Nowadays it is a by-product of the oyster, freshwater pearl mussel and abalone industries.
• 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.
• Rolled Gold - A type of gold plating devloped in the early 19th century, similar to Sheffield plating of silver, where the the gold is fused under pressure and heat to a base metal, usually brass, and then rolled into sheets of the required thickness.
  
  The thickness of the gold plate can vary. In Britain the thickness of the gold is measured in microns. A micron is one-thousandth of a millimetre and 20 microns of gold is considered good quality. In the USA a differnt method is used that takes account of the total weight of the object.
  
  Also, the purity of the gold, measured in carats can vary, with 24 carat being the purest. The gold in most rolled gold objects will be between 9 and 14 carats.
  
  There are other chemical and electroplating methods of applying gold plate to a base metal, but rolled gold is considered a superior plate to a "gold plated" object.
  
  Depending on the country and date of manufacture, the object may be stamped "Rolled Gold" or similar, but if there is any doubt as to whether an object is solid gold, or some type of gold plating, it is preferable to have it tested by a jeweller.
