Vintage Sterling Silver Navajo Native American 30s 40s Onyx Agate CUFF Bracelet

This is a FABULOUS vintage sterling silver cuff from the late 1930's or early 40's. The bracelet features 3 intricately hand stamped bands of silver on each side. The center stone is a very dark agate that I thought was onyx but it shows some red tones and striations under the light so I think it is an agate. It is a big stone measuring 1 3/4" x 7/8" wide and the bracelet interior measures 5 1/8" with a gap of 1 3/8", A VERY nice older cuff for your collection!
