This is a flat hand specimen of siderite. Both top and bottom are covered with a druze of siderite crystals, some areas of which are red, some gray. The gray crystals appear translucent, and these provide a great deal of sparkle and a pleasing optical effect on the surface. A loupe reveals that the top surface consists of thousands of small botryoidal formations, each of which displays consistent crystal faces with an iridescent reflection.
