Love these old sterling enamel bangles. This one is wide, with cobalt blue, turquoise blue, and green enamel stripes. Width is approx. 5/8". The bangle is hallmarked "sterling". The bangle has raised engraving and a fancy border. The enamel colors are vivid. Inside diameter is approx. 2 3/8". This bangle fits my average 7 1/4" wrist with a little room to spare. There is a silver safety chain, and a snap type clasp. This clasp snaps closed tightly. Weight is 31.5 grams. Condition is excellent for age. I would date this great bangle at c1950's.
