This special brooch is completely encrusted with Austrian clear crystal rhinestones, all prong set.  The only place it is not covered with rhinestones is the bottom and the back.There are teardrop shaped rhinestones at the base of the cup and the top of the foot.   It is in great condition, no missing or darkenened stones. The pin can be a bit tricky -- it seems to hold securely with fabric, but can come unpinned when no fabric is in to hold it taut. I love how three dimensional this brooch is, even the champagne "bubbles" (prong set rhinestones set on wires)  extend and "float" above the glass.  The brooch is signed "Bauer" on the back and is a great example of Dorothy Bauer's sculptural style of jewelry design. It is from the 1980s and made in the United States from high quality materials and has high quality craftsmanship.   This would be perfect to celebrate a special occasion with, either to wear or as a special gift.  A lovely and highly collectible brooch!
