Rare specimen of ocean-blue fluorite decorated with crystals of aegirine from the famous Mont Saint-Hilaire, Canada. The fluorite crystals are micro cubes. The color is very pleasing. Elongated black aegirine blades grow above. For references see the 1990 issue of The Mineralogical Record vol. 21, # 4. In good condition - some contacts. On acrylic base.

Marvelous!
