"Proud Air Force Mom" is hand stamped onto a 1.25" aluminum washer. An "I love my airman" charm tops this off. Hangs on an 18" sterling silver plated snake chain. Aluminum is very light weight but very sturdy. It will never rust or tarnish. Hand stamping is done one letter at a time with a hammer and a shank. Spacing, alignment and depth may occur due to the hand made nature of this piece.
