RARE David Yurman Exotic Stone Cufflinks

David Yurman exotic stone cufflinks. Very rare and hard to find and no longer sold. I believe these are Picasso Jasper, they are a light gray and black streaky stone. I have never seen another paired listed and they do not make this version anymore. Marked DY 925 (sterling silver). Comes with a pouch. Could use a professional polish. Be sure to check out the other cufflinks I listed, my husband has many pairs he does not use much anymore.
