3 sweet and dainty enamel on sterling vintage pins, all in as is vintage condition; flawed with chips to the enamel. The clasp for pin back on the smallest is broken off; additional mark in diamond shape but can’t read it. The green & white pin with rose in center has sterling stamped twice & another small illegible mark; clasp is not very secure. Mostly white pin is stamped sterling, no other hallmark; clasp works well. Unfortunate that these are damaged, the background designs are intricate. Another Posher told me these are called “guilloche.” Bundle and I’ll offer a discount plus you save on shipping.
