Vintage Micro Mosaic Bar Pin Made in Italy

Older Micro Mosaic has C-Clasp closure so it sis possibly before 1921 Stamped Made in Italy The tiniest of mosaic pieces create multi colored floral on this piece. I am always surprised that these pieces hold up so well for being as tiny and appearing so fragile. This item is in good condition, the pin on backside however does have a bit of a bend to it that perhaps new owner will straighten out. The metal is brass and could be polished up as well.
