An excellent floater group of hexagonal apatite prisms and some really nice gem siderite on the back. The apatite is strongly zoned inside, featuring an exterior layer filled with fluid inclusions and a gemmy inside core that lights up green every time the piece is backlit. It is also worth noting that the crystals show excellent glassy luster and very sharp faces, so overall very rare material for what is actually coming out right now. This piece comes from the classic Portuguese deposit of Panasqueira, a mine developed to exploit a series of tabular veins of Sn–W mineralization that have produced some of the finest sulfide and fluorapatite specimens in the world and definitely from Europe.
