9K Gold & 1000 Pure Silver Vintage Parthenon Charm

A beautiful charm featuring a gold Parthenon center with gorgeous etching details inside a thick and flower themed frame of pure silver. 🏛️Marked 1000, for pure silver 🏛️7/8” by 15/16”, large pendant ‼️The front of the yellow gold is super clean and buttery, but the back has some fire scale, scratches and debris, I’m guessing from the pieces being soldered together? The front tests positive for 9K, but the look of the back of it makes me unsure about whether it’s gold filled or solid.‼️ The pictures make it look more silver, but the center is a yellow, almost rosy gold color. There is no tarnish to the front gold center.
