Golden Lustre Amphora

• Carat - A carat (abbreviated "ct") is a unit of measurement used to describe the weight of a diamond or other gemstone, and separately is a unit of measurement used to describe the weight of precious metals such as gold,.
  
  For gemstones, one carat is equal to 0.2 grams or 200 milligrams. The weight of a diamond is one of the Four Cs (along with cut, colour, and clarity) that are used to determine a diamond's value.
  
  It is important to note that a diamond's weight does not necessarily correspond to its size. A diamond's cut, which affects how well it reflects light, can make a diamond of a lower weight appear larger than a diamond of a higher weight. Additionally, the carat is not the only factor to determine the value of a diamond, other factors such as clarity, colour and cut are important too.
  
  In the gold industry, the purity of gold is measured in carats (abbreviated "ct"), with 24 karats being pure gold and lower carat numbers indicating a lower purity level. So, for example, 18 carat gold is 18/24 or 75% pure gold, and 12 carat gold is 12/24 or 50% pure gold.
• Lustre Ware - Lustre decoration on ceramics is created by painting a thin deposit of metal oxide such as gold, silver or copper onto the surface, and then firing the item again, so that metal oxide forms a thin film on the surface. The finished effect is a shiny metallic surface. The technique was used in the 19th century by potteries such as Crown Devon, Grimwades, Maling, and Royal Doulton. However the best known use was by Wedgwood for its Fairyland lustre.
