This sterling navajo necklace has a purple spiny oyster stone with silverwork around it. The necklace is almost 17" long with a 2" adjustable chain. The necklace is stamped by the artist, "S.T.so". I have only worn this necklace once and is in excellent condition. Due to not wearing it alot, I am selling it and hoping to recieve what I paid for it. I purchased it off of CalliCo Silver.
