A cool aegirine blade from this famous locality - Mont Saint-Hilaire, Quebec, Canada. It is an elongated 44 mm crystal with a black color and a strong luster. It is very well shaped. A colorless albite gives a good contrast. It has an attractive display on both sides. For references see the 1990 issue of The Mineralogical Record vol. 21, # 4. In very good condition – some small contacts. On acrylic base.
Wonderful!
