Selling a Tungsten Carbide Wedding Band Size 10. Long story short, I lost my wedding band and bought this to replace it. Sure enough, I found my old one before I even wore it. Bought it from Kay Jewelers. It''s a size 10. Never been worn. It has a golf ball like texture which seemed different to me so I liked it. Made of tungsten carbide. Can provide a copy of receipt if wanted/needed.
