Another set that has languished on my desk for awhile now - the disc have passed the strong magnet test but they are not stamped - I think they came off a vintage clip set that was distressed and perhaps rhodium over sterling.
there's tiny leaves and berries surrounding the middle hammered disc. Hope you can make that out.
I teamed them up with a pair of genuine moonstone 7mm beads and sterling silver spacers and sterling fish hooks. The set weighs over 10 grams - never worn - mint condition. Only set I have.
