Vintage Blue Rhinestone Circle Brooch & Pendant Frosted Glass Leaves MCM 1960s

Really beautiful and sparkly, mid-century brooch. The gold tone brooch has pale or princess blue rhinestones, periwinkle glass molded leaves and one AB blue rhinestone. It can also be worn as a pendant. It has a mark on the back but is illegible to me. Maybe Austria??? Pre-Owned Condition: shows minimal wear Size: 1 1/4"d
