Love the feel of this bracelet! It is not rigid at all but so supple that it molds to your wrist. I could not find a mark but I did test it and it is sterling silver. It has a secure spring ring clasp and measures about 8 1/8" long. This is a great piece of every day wear or for layering with other bracelets. There is a minor amount of patina. Bracelet weighs about 34 grams and is in excellent condition.
