This is a huge, fine crystal of fluorapatite from the world famous Panasqueira deposit which has arguably produced the finest specimens of this species. This crystal is literally monstrous for the locality! It consists of a deeper-colored green core covered by a layer of secondary apatite. The gray-green crystal is glassy, translucent and is studded with tan rhombs of siderite, to 2.0 cm across. There is minor edge wear but this is one super fluorapatite where, in the context of the remarkable size, a bit of edge wear is certianly forgiveable I think. It is very nearly complete all around, impaled upon a ferberite crystal that partially sticks out the backside
