The marks in this superb bracelet are Taxco EDP 925 Hechoen Mexico in a circle (there are 3 more marks that i cannot make out)...underneathe the circle it has Sterling. The hinge on the bracelet is nice and tight, and the inner diameter is 2 1/4 2/12. The front of the bracelet with both parts closed measures3 3/4 inches and the back is 1 inch at the hinge. The patina of the silver is wonderful, and I have only lightly polished it.
