 Goa stone

A Goa stone or Lapis de Goa was a man-made bezoar that was considered to have medicinal and talismanic properties and were manufactured from Goa, India and exported to apothecaries in Europe from the mid-16th to 18th century.Goa stones were manufactured by Jesuits in the late seventeenth century in Goa because naturally occurring bezoars were scarce.
