Item Description

A classic association specimen from Panasqueira featuring a few sharp, lustrous, soft green colored crystals of Fluorapatite measuring up to 7 mm across associated with compressed tan hexagonal crystals of Siderite measuring up to 5 mm across, sitting on a matrix covered by bladed dark brown Muscovite.
