Most 'real' native american rings wont have what we, in the states R used to seeing-925-stamped on it. Or even silver/sterling etc.Usually their mark or ? @ least thats my finding. An at times the stamp of 925 isnt true silver-I've learn the hard way on tht. In old'n times 'ones' would test the 'metal' so to speak by touching it 2 their teeth-tongue etc. really they did. FYI Ula
