This is a gold-tone brooch/pin; it is 1 3/4 wide, unmarked but after the style of Schreiner. Just gorgeous with its inverted, unfoiled stones. It has light pink to raspberry pink. I think the tear-drop stones are actually clear but are picking up the reflection of all the pink surrounding it, all prongs set in smooth gold tone metal, just gorgeous!
I have other pin pieces listed separately in my store.
