A superb specimen. It is a group of very sharp fluorapatite crystals, one of them principal showing a more than excellent brilliance, green color zoning, striated faces on prism… It is very aerially disposed on a matrix of brilliant muscovite, with arsenopyrite. A very representative piece for this classic Portuguese mine. THE MAIN CRYSTAL IS: 1,8 x 1,6 x 1,1 cm. Fluorescence UVC.
