The listing, jewelry lot, some .925, some vintage... has ended.
There is
a 28" snake chain that is stamped .925
a vintage rhinestone or austrian crystal necklace (not stamped)
a vintage rhinestone pin (not stamped)
a silver ring with what looks like a green moonstone-stamped .925
and 2 silver rings that are not stamped, but may be sterling. I wear the exact same rings myself (pic) and they don't discolor my skin-so that's anyone's guess.
