Made in Mexico and dating to the 1960s/1970s or so, may I offer this silver ring featuring a slightly concave top, nicely etched, upon a nice band width. Condition is very nice with no problems I can spot.
Metal Content is Sterling Silver with Hallmarks of JRC 925 ECHO EN MEXICO
On my sizer, the ring measures 5-1/2". The circular top measures 13/16" across. Weight is 4.5 grams
