Such a fabulous figural! Circa 1940's, large turtle pin has pave set clear rhinestones on its body surrounding a pale pink faceted crystal on its shell. It is set in rhodium plated metal and in excellent condition. There are the 2 letters on the underside of its tail, LU or LL(?) I have not been able to determine the maker.
It measures 3.25 x 2 inches. There is a tiny bit of enamel loss by its eyes.
