The listing, 2 "abalone" look bracelets-beautiful! has ended.
The one that has circles is quite heavy metal and lays beautifully but is not marked with stamp. The one with the small squares looks like abalone or similar (mostly darker blues) and is marked S 80, a little lighter weight but just beautiful! They seem to be around a size 7.5 (the circular "yin-yang" one has an extension also with a small heart hanging off it. Love them (they were a gift) but they are too big for me. Hate charging for mailing but cannot send otherwise. Thanks for looking!
