This is a hand made chain. The chain is made from 12 gauge, saw cut titanium links and solid punched zirconium rings. The Zr rings have been given a heat patina giving them a dark grey/black finish. The termination is a titanium clip and solid machined Zr link. 

The bracelet is 10 3/8" long and 3/8" across. I can resize this chain without any problem.
