Tane Orfebres has been Mexico City's Tiffany since the 1950s. There current catalog shows bracelets in silver and gold plate for $1200. The set has links in sterling with gold plated over silver connectors. The necklace is 18 1/2" by 3/8" with a flip clasp. the bracelet is 7 1/2" by 3/8". The post earrings are 1 1/8" by 3/8". The necklace is marked TC-16. This artisan is mentioned in Hougart as having this mark on Tane. I am assuming that (s)he worked for Tane and and moonlighting for himself/herself as well. I own a number of Tane pieces and the only difference is the two clasps, which on Tane are fold over clasps with Tane impressed into the face of the clasp. On this set, pieces are also marked Mexico and 925. Excellent vintage condition. Made after 1978. It is a wonderful set.
