Airy rhinestone pin by DeLizza & Elster. The tiered construction has clear rhinestone florets with teal rhinestone centers. Throughout the rest of the brooch are olivine green navettes, and Capri blue and purple chaton (round) rhinestones.
The tiered construction, florets, and figure eights on the back all identify this as Juliana jewelry.
In excellent condition, it measures 2.25 inches across.
