Vintage Red Glass Maltese Cross Brooch

Rare piece! This brooch is stunning, and is made of triangle shaped glass. There is a pendant hook on the back. I don’t know the maker or the decade for sure. I would guess mid 1960’s. It’s unsigned about 2.25”x 2.25” and in great condition no chips. See pics. It’s also quite heavy. flawless for everyday use. supreme materials and excellent craftsmanship ensure long-lasting durability.
