Hi,
first of all I like your motto...
The nice Little weight seems to be a rondello weight, made by St. Mande in France around 1850/60;
a similar design was made by St. Louis during the same era and a bit earlier, it is often called "garlanded rondello" weight,
the St. Louis pieces are a little bit more elaborate, the covering glass (lead Crystal in both cases) of St. Louis is brighter and
clearer, the layout and millefiori more "sophisticated" -means well placed- St. Mande's domes have a greyish tint more often.
I do not yet know which is more frequent...
for a more definitive attribution, UV test and/or cane matching will be required, St. Mande shows gray-yellow or gray-green UV reaction,
whilst St. Louis should Show a pink (salmon?) shade,
A neat find anyway! Cheers from l'Autriche, Erhard
