• Assay / Assayed - Assaying is the testing of a metal, most commonly silver and gold to determine its ingredients and quality. In Britain, once an item of silver or gold has been assayed, a mark is stamped on it, certifying its purity. Known as hallmark, it derives its name from the Guild Hall of the Goldsmiths' Company, who recieved its Charter in 1327 giving it the power to assay and mark articles of gold and silver.
• Carnelian Glass - Carnelian glass is a type of glass that is colored red, orange, or brownish-red. It is made by adding iron oxide to the glass mixture. The color of carnelian glass can vary depending on the amount of iron oxide that is added, as well as the firing temperature. Carnelian glass is often used to make beads, jewellery, and other decorative items. It can also be used to make stained glass windows and other art objects. Carnelian glass is sometimes called "carnelian chalcedony" or "carnelian quartz."
  
  Carnelian glass was first made in the Roman Empire. It was also made in ancient Egypt, Greece, and Mesopotamia. Carnelian glass was not made again until the Renaissance, when it became popular again. Today, carnelian glass is made in many countries around the world.
• 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.
• Malachite - Malachite is bright copper-green coloured stone with concentric layers which displays distinct contrasting veinings. It has been valued in the past for making or decorating small precious objects such as clocks, jewellery, dishes and so. In the Orient it was used for snuff bottles and in Russia and was favoured by the Faberge workshop. larger pieces were used for table tops.
  
  The principal source of supply was Russia but it is to be found in other regions such as Southern Africa, Mexico, Australia and France.
  
  Malachite glass is a manufactured material that was intended to resemble malachite, but often bears more resemblance to a veined coloured marble due to its lower gloss finish and lack of concentric layers. Malachite glass was manufactured by many glassworks in the 19th century including Loetz in Austria and others in Bohemia and Davidson's Greener's and Sowerby in north eastern England.
  
  It was particularly used for scent bottles, bowls, and small vases often decorated with nymphs.
  
  Malachite glass has been manufactured continuously since the late nineteenth century, most is unmarked and it is difficult to distinguish the age or manufacturer of most commercial pieces.
• 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.
