This byzantine chain is constructed with 11mm stainless steel jumps. The result is a chain that is a little over 11mm thick. They are not soldered closed so you can simply remove links to tailor the chain length for your purposes.
A 15mm (or larger) lobster clasp can be added to each end using one of the jump rings.
This listing is for 1 meter (over 3 feet) of this chain. It does not have a clasp attached.
Each link is 11mm in diameter and 2.1mm thick.
This chain is hypoallergenic and won't tarnish.
