Hobe took a serious proprietary interest in this possibly-1960s flower power brooch. Every large petal casting in marked Hobe! That's 7 marks I can see. It measures 2 & 1/4 inches in diameter and is embellished with faux carnelian glass beads. Did we ever really wear these colors? The matte satin glass petals are unusual......not givre glass exactly, but some yellow in the opalescent meld. It is in excellent condition.
