3 are marked 925 (stands for sterling silver) on inside... the other one is silver but has a mark on the clasp but is unclear what the mark says. All 4 bracelets have a beautiful patina.
Condition: All are vintage (used ). The wide bracelet has 2 small pings/dents inside (does not take away from the bracelet). It also has an indentation on the outside by the clasp - hard to see due to pattern on the bracelet, but I wanted to point it out. Clasps are all sturdy, hinges are sturdy - these will be a great addition to your collection and so fun to wear - you WILL get compliments! All are beautiful and classy.
