Large Men''s Bolo Tie with a Agate Slice. Bolo Tie showcasing hand polished slice of Agatized Petrified Wood. You can even see the growth rings that are preserved in the agate! It is mind bending to think that at one time this was a piece of a living tree!!!! To enhance the rustic beauty of this stone we only hand polished it and left it looking almost like we found it. Genuine Black Leather Cord and it is really comfy to wear!!! Nice weighted fancy end caps that are gunmetal gray in color. Nice gift for men or women.
