Quartz with Siderite.
JFD14AN5: Quartz with Siderite
Vizille is a classic French mineral locality where many alpine quartzes and very good (and very large) siderites have been found. I kept this piece because I really liked that Quartz, alone and tall in the middle of the piece, and because the specimen was a floater, with a single large Siderite crystal in which are the Quartz and a second generation of siderites, with smaller and lighter colored crystals.

Quartz with Siderite.
NM47AC6: Quartz with Siderite
Strongly etched Quartz crystal with very deep dissolutions forms. It is transparent and is partially coated by small Siderite crystals. Very different from the usual Quartzes from Panasqueira, if it was not for the distinctive associated Siderite, it could seem an Alpine Quartz. The upper levels of Panasqueira are currently offering surprising and pleasant novelties, with samples that are different from what is already known.
