Assorted Silver Brooches and Tie Clips Set

• Marcasite - Marcasite is a mineral, iron sulphide, but is rarely used in jewellery. Instead marcasite is the name given to iron pyrites, the mineral sold as marcasite which is identical in copmosition to iron sulphide but crystalises as a cube, making it more suitable for jewellery. It is a brassy yellow in colour and is also known as "fool's gold", and sits well with silver rather than gold becasue of its colour.
  
  Marcasite has been used in jewellery since ancient times and became popular again in jewellery in the 18th century, continuing through to the early 20th century, with the settings becoming cheaper as time progressed, eventually earning the sobriquet "costume jewellery" along with other cheap jewellery that was made for a prevailing pattern and meant to be changed with each new outfit.
• Niello - A compound made up of lead silver copper and sulphur that is black in colour, and applied to the engraved areas of silver items, thus highlighting the engraving by making the black niello detail stand out from the silver background. It was used on edged weapons from the Renaisance onwards, and also by Russian crafstmen of the19th century.
