Charms I recast from antique and vintage pieces are often not stamped .925 to indicate sterling silver. Old pieces did not have this on them especially old european or foreign religious pieces. I will not compromise a design by cramming in a .925 stamp. If you feel you must have something that says. 925, I'll write it for you on a business card. Any piece can be tested by a jeweler. All my pieces are made in the USA.
