This is one phenomenal sterling silver necklace. The beads are strung on chain and it has a secure clasp. Beads are about 8mm and necklace measures 24 1/4" long. It weighs in at about 70 grams. There is some old patina on the necklace. I left it the way it was when I purchased it. It is a wonderful length and will be perfect with many things. Almost everything I can think of looks great with sterling, especially this amazing classic. Necklace is marked 925 Italy.
