it is stamped .925..and is solid...it never has been tested..but have sold 100's..of them..as i make pendants..nobody ever had a complaint..and it holds up well..purchased from a reputable dealer...i learned on here make no guarantee's...my opinion is that it is...
this is the only one on my computer..it looks exactly like the pic..it is square links..and the clasp is welded on..which if you look it up is a sign of a very good necklace...:)))
