This unusual Tane necklace is made of circular links that terminate with round balls. They are strung on a rubber cord measuring 17 inches long. It has a magnetic clasp with a safety loop. The necklace is not signed by Tane but comes in their presentation box. From a practical point of view, there is not a place where the maker could have put their stamp as every bit of it is textured. It is a mate to the signed Tane bangle bracelet listed as item #1429548 "Tane Silver Dots Bangle Bracelet". Tane has been known since the early 20th century as Mexico's premier silversmithing firm.
