This is a wonderful brooch by Schreiner. Sometimes hallmarked Schreiner of NY. The brooch has dark grey metal, and the rhinestones that have open backs are foiled. Colors in this piece are purple, amber, blue, peridot and hot pink. This piece would look terrific on any color suit. Size is 2 3/4" X 2 1/4". Clasp is a safety clasp that holds well. All of the rhinestones have many fancy prongs. With a 10X loupe I can see very minor clouding of the light rhinestones, and some surface dust. Otherwise the brooch is in very good condition. None of the stones are damaged. I would date this fine Schreiner brooch at c1950's.
