These fluorapatite crystals are a curiosity from this Portuguese mine. They appear as groups of prismatic crystals with striated faces, truncated by the pinacoid. What makes them more remarkable is the colour zoning between the inner lower crystal, with violet tones, and the colourless upper middle part. It is accompanied by muscovite. The main crystal is: 2,0 x 1,7 x 1,3 cm. 0,78 x 0,66 x 0,51 inc.
