If it has scratches, it means it served its purpose. If it's cracked I will write it in the notes and add a photo. I test all of the bullion items I sell with the Sigma Precious Metal Verifier Pro whenever possible. For all other coins and jewelry items I test them on the Fischer Goldscope SD 520 XRF.
I test all my diamonds on the GIA iD100. Please be patient if I don't post feedback immediately, I always do it eventually. Anything other than that can hopefully be settled with communication.
Always please feel free to ask questions about my items, my past items, or other stuff I might be able to get.
