Rhinestone Bar Pin with Topaz Rhinestone Emerald Pear Chaton and Navette Cuts

This is a lovely bar pin made entirely of rhinestones. The central stone is an emerald cut Madeira Topaz with Madeira Topaz pear cuts on either side. There are yellow topaz navettes and chatons that form the rest of the bar pin. It measures 3/4 tall and 2 3/4" wide. It looks like a DeLizza & Elster piece but i have never seen one like this and the pinback is wrong. Still a lovely piece.
