This is a gorgeous large plate of glassy, undamaged, vibrant yellow fluorite crystals with sparkling chalcopyrite inclusions from the famous Minerva #1 mine in Southern Illinois. In exceptional condition for a piece this large and very showy with bright luster and wonderful deep amber-yellow color. Ex. Roger Bennett collection, Ex. Glen Killberg Collection. These are getting rather hard to come by in this size and quality range these days. Classic! Mark Cross photo.
