Mont Saint-Hilaire, Berthierine

Excellent specimens of this unusual mineral. They are sharp pseudo-hexagonal crystals with "sandwich"-like zoning parallel to the "c" face. Look very much like donnayite!

  • much of the top part of this massive analcime is a vug lined with sharp, pure white analcime crystals. There are quite a few nice, green, lightly zoned berthierine crystals on the white analcime which provides a nice contrast for examining them.
