Flavorless Cookie Jewelry

I was going on some kind of trip, I think, and before I was about to leave I was in a hotel room and looking at a magazine ad for jewelry - apparently this jeweler classifed their wares upon how 'fresh' they were. I can't remember the exact terminology, but I think the kind the model was wearing was considered "fine" and "rough cut". It was advertised as being like the kind of exfoliating soap she might use on her face to remove makeup. I decided to eat the earring, and it tasted like a flavorless cookie bar.
