Bracelet Marked 925 on the Clasp see picture ... Sterling Silver Tube Clasp ...Multi beaded 5 Strand Bracelet .. Black gemstones ( maybe black onyx ) but I'm not an expert in stones so please see pictures with gem tester, definitely not glass ... About 50 grams ..... About 7" long, end to end with clasp included ... I recommend this bracelet for a wrist smaller than 7 inches because the clasp tube goes inside the other, see picture ... Great condition with some tarnish on the silver ...Pictures are part of the description .... Please ask all questions important to you and please see pictures for all details and measurement .... Thank you.
