The listing, Vintage 14k Rose Earrings and lapel pin, read description ! has ended.
I believe these to be vintage Krementz, they did 14k overlay, 14k gold filled and some actual 14k solid gold. I acid tested these and they do pass a 14k acid test, however I am selling them as gold filled because the vintage stuff had a much higher quality of gold filled than the stuff you get these days. Sorr no backs, the pin back and post on the pin did not test for gold. I will include a pair of rubber backs on request. No markings that I could find.
