Bulgari Chandra Necklace with Coral and Lapis Lazuli

• 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.
• 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.
• Coral - Coral used in jewellery. Coral is a material that is commonly used in jewellery making. It is made up of the skeletons of tiny marine animals called coral polyps. There are many species of coral, but only one group, Corallium, is suitable for carving, and thus can be used in jewellery manufacture. These have a deep red or pink orange skeleton and are known as "noble coral" or "precious coral".
• 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.
