Fluorite – Valzergues, Villefranche-de-Rouergue, Aveyron, France
 
Gorgeous yellow fluorite with sky blue zonings. Depending on the light, the yellow appears almost orange. 
The transparent crystal shows the contrasting interplay of blue and yellow zoning in a beautiful way. Also typical of these crystals are the rarely occurring rounded surfaces at the corners, in which the rectangular edges flatten towards the corner. 
Colorful collection piece in excellent condition, size and wonderful quality.
