JFD38AN7: Quartz with Fluorapatite inclusions, Cassiterite and Siderite

Quartz is ubiquitous in Panasqueira and appears there in a great diversity of habits. In this floater, recrystallized at its base, what is attractive, in addition to its transparency and perfection, is the presence of a Cassiterite crystal in the center of the piece and the numerous inclusions of Fluorapatite crystals, a very rare inclusion due to the very different formation temperatures of Quartz and Fluorapatite. Completing this combo piece is the presence of Siderite on the back. I bought it from Alberto Ledo in 2014. Alberto is part of the new generation of Portuguese dealers who go often to the mine and sometimes get great specimens from there.
