This is a hard-to-find ring made by G&S (Gordon and Smith) featuring an American Indian warrior chief head and is engraved "Indian Motorcycle" as pictured. This ring was acid tested as solid sterling silver 925 and weighs 21.5 grams. Stamped G&S - 1984. Measures as a size 11 on my mandrel. Excellent condition which means it has no damage, only normal use marks from being worn. It has not been polished and has a wonderful warm patina.
