Silver Waterfall Tassel Earrings

These earrings have great movement, which simply cannot be captured in photos. Each tassel consists of 9 very fine silver chains measuring about 2 1/8" long. Purchased in Mexico in the mid 1980's. No stamp that I can find, but I know I've polished them before wearing for that pretty shine, so they may be sterling - I just don't know. Fun to wear for an evening out.
