Roundel Design - Unknown Factory

An excellent millefiori roundel design most likely of Belgian origin. Within a garland of green/blue millefiori canes and set over parallel latticinio rods, 5 roundels with complex millefiori canes encircle a centre green/white roundel. Most of the canes -  including those at the centre of the roundels - contain, or are composed solely, of 6-point star canes.
Polished, concave base with wear ring.
(see 2016 PCA Bulletin for articles by Paul Dunlop and Alan Thornton/Andreas Stammwitz with descriptions of similar canes)
