Honestly do not know what this is made of, but it looks great! The metal is heavy, and has not tarnished with storage. There is slight wear on the edges of some of the conchos. The stones are smooth, but "chink" when touched together. It has metal studs between the conchos, but not between the two that are next to the holes (see photo). The conchos slide on the leather belt between the studs for fine tuning the spacing. The leather is in good condition. The belt is 36 inches long. The large concho is approximately 3 inches x 4 inches, and the others are approximately 3 inches x 3.25 inches. Thanks for looking!
