Fluorite – Trepas, Tarn, France
 Sharp-edged, highly lustrous fluorite with numerous clearly defined phantoms. French fluorites are known worldwide for these distinct phantoms and are highly sought after. The transparent crystal impressively displays this contrasting interplay of blue and yellow zoning. Also typical of these crystals are the rare rounded surfaces at the corners, where the rectangular edges taper towards the corner.
