Delightful & delicate 10K gold chain made in Italy

This is a 15-inch gold chain in a box pattern. It weighs 1.2 grams and is marked 10K Italy on one part of the clasp and 60 TV (after a star symbol) on the other side. My research indicates TV stands for Treviso, Italy and 60 is the registration number for the jewelry firm Tecnigold founded by Francesco Piotti in the 70s. The chain is in excellent condition. (d)
