74mm x 55mm x 26mm
Single Fluorapatite crystal with a thin tabular shape and with a very well defined concentric color zoning. On a matrix of Arsenopyrite crystals with botryoidal Muscovite aggregates. At Panasqueira this kind of concentric growth, differentiated on the periphery and the central area, is well known as ?olho de boi? (ox eye), a particularity that is especially obvious on this sample.
