This is the first try at a chain like this.
It's a pretty hefty wallet chain, the clips at each end are 42 mm titanium with stainless springs. The chain is made of alternating sections of soldered 10 gauge sterling silver and titanium beads. Each bead is 5/8" in diameter and 1/4" thick. The titanium has been heat colored to some bronze and blue colors. The sterling was given a liver of sulfur patina. The chain is 18" long from the inside of the clips. All of the components except for the clips are hand made, by me.
