I have a silver bracelet made by Darin Bill a navajo silversmith. it is a very heavy and thick piece. He has sence passed and I never got to ask him how he managed to stamp his designs so deeply. I was wondering if there was a person familiar with his work who might shead some light on the subject. He was also well known for stamping designs on both sides of of his work. pleasefeel free to drop me a line if you have any answers.
