This is a vintage sterling silver and rhinestone bug or butterfly fur clip. It is simply marked Sterling and I don't know who made it. The body of the bug is a deep emerald green open backed rhinestone. The head is a brilliant clear rhinestone. There are two small amber yellow rhinestones between the wings. The clip measures 1-1/2 inches in diameter. It is in very good condition with minor, if any, loss of gold tone. However, it may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
