2-row Concentric - Unknown Factory

Possibly of Belgian origin - a neatly set, low domed 19th Century concentric with a star-cut base.  The 2 rows encircling the pink/green corrugated millefiori cane in the centre are made up 5 different types of millefiori canes most of which contain 6-point stars.
The star-cut in the polished, concave base extends almost to the very edge.
(see 2016 PCA Bulletin for articles by Paul Dunlop and Alan Thornton/Andreas Stammwitz with descriptions of similar canes)
