I was going to say it looks ok to me. I have some cringle flake that scared me when I opened it but after seeing it sparkle in the sunlight and actually viewing the crystal like formations under magnification I was pleased.It appears to, but I'll check it in the sunlight later. With a flashlight, I definitely see some sparkle. Plus, it's been almost a month since I cracked the tin and I haven't seen any additional growth. I'm thinking it might be ok.
