George Addis Moonstone Paste Brooch

• 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.
• Verso - Verso is the "back" side of a sheet of paper, art work, coin or medal. The front side is "recto".
• Paste / Rhinestone / Diamante - Paste (or rhinestone or diamante) is the name given to a coloured glass composition used for imitation gemstones, or to imitation gemstones made of glass.
  
  Although the technique of glassmaking had been known for thousands of years, but it wasn't until a lead glass with similar optical properties to diamonds were invented by a German jeweller working in Paris (either "Stras" or 'Strasser") in the early 18th century that "paste" gemstones became popular.
  
  There was no social stigma attached to wearing imitation stones, and they were worn in situations where highway robbery was a possibility. The 18th century settings were of very high quality, equivilent to real gemstone jewellery.
  
  In the nineteeth century the quality of paste jewellery declined and it has remained the poor cousin to genuine gemstones ever since.
