Half of this specimen is covered with colourless fluorapatite crystals while the other half is covered with a mixture of sharp, dark green, kulanite crystals, associated with siderite, quartz and fluorapatite crystals. The kulanite crystals are great! Interestingly, the specimen is dotted with bright orange growths of a lichen, indicating that this one was exposed to the open air and collected with the lichens on it. Interesting piece!
