THIS IS A BEAUTIFULLY CUT HEAVY CRYSTAL ROUND BOX.  WITH A LID.
IT IS CUT IN CRISS CROSS PATTERN AND HAS A STAR CUT BASE.
IT MEASURES 7cms HIGH and 8cms ACROSS.
it weighs 444g.
The only damage is a small rim chip on the lid.  Not really too visible on the outside.
Possibly Victorian - maybe up to 1920s at a guess.
