This is a beautiful brushed gold tone pave' rhinestone day and night convertible brooch. It is signed Kramer and marked Pat. Pend. The gold tone brooch has a sliding top so that it can be worn open with the rhinestones showing or closed so that it is just a brushed gold circle. The brooch measures 1-7/8 inches in diameter. The brooch is shown in silver tone in the Kramer section of the book, Signed Beauties of Costume Jewelry by Marcia Brown. This brooch is in very good condition and does not appear to have been worn. There are no missing stones. However, the brooch is vintage and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
