This is Tanzanite. The case is dirty. The contents are clean. I got this from a UFO catcher (claw machine) a few years ago. I'm selling it because I don't use it. Perfect for those who do handmade crafts. Please make your decision based on the images. If you'd like to see any other areas, feel free to comment. This is a used item. Please refrain from purchasing if you are concerned. Please see my profile. Thank you very much. (m(_ _)m)
