The engraving is a little faded, but I believe it's likely Chrome Hearts, as a family member said they purchased it. There is no certificate of authenticity. I am not very knowledgeable, so please judge from the photos. (The colors in the first and second photos are close to the actual item.) I will ship it in the case I have been storing it in, if desired. Chain length: Approximately 93cm I can add more photos if you would like. Scratches/Discoloration: None
