Large Navajo sterling silver concho sash belt buckle or handkerchief slide. It is convex in shape and has a raised design achieved with the repoussé technique as well as stamp decoration. It is lightly stamped on the back sterling in block letters. When I purchased this I could not find the stamp anywhere. Just found it! 

Measures 3” by 2”. The opening at the bar is 1 1/8”. Weight: 24 grams. Excellent condition. First one that I have ever found in this size.
