For sale is this tested 12k gold, Victorian era, gold Bookchain Mesh Bracelet clasp. The enameled plaque/clasp in the center is engraved on back and measures 5/16" x 7/16". It has a tasseled end and weighs 2.3 grams of gold. There is minor enamel loss. The last picture shows an intact bookchain bracelet with the same clasp that I'm selling separately. If you've got a strand of gold bookchain it would not be difficult to restore it to another bracelet.
