Mexican Sterling retailer Concave Bangle Bracelet

This pretty sterling concave bangle was made in Mexico. It's in good vintage condition with some wear. The worst of the wear is a small ding along an edge (best seen in pic #8 at about 3 o'clock). The circumference of the bangle is 8 1/16 inches and measures 3 inches across. It's 5/8 inches wide and weighs 30 grams. It's stamped Mexico 925 and was made in the 80's or 90's. Sorry about all the reflections in the pictures, it's retailer very shiny.
