This is a solid sterling silver dog collar and hollow bone charms. The collar measures 1 1/8" in length with the attached (leash) bail ring by ¾" in width and it is marked 925 for silver content. The dog bone measures 1 ¼” long by ½” wide and is made of hollow construction and tested as sterling silver. There are minor surface scratches that come with age and I believe it is 1980s vintage. The charms are attached to a rope chain necklace measuring 23 ½” in length by 2mm wide and marked 925 Italy on both ends, the clasp is in working order and also marked 925. The total weight of the charms and necklace is 17 grams. This would make a great gift!
