Square French jewellery casket measuring 6.5cm by 6.5cm by 6.5cm, with a Parisian scene to the lid.
The thick lead crystal glass cleverly gives a slight magnification to the contents and the all round glass windows give light to show your little bijoux to their best effect.  Age related wear, a fantasic addition to any dressing table. 
These were extremely popular souvenirs for those rich enough to take the "Grand Tour" of European countries in the 18th & 19th centuries.
