Mont Saint-Hilaire, Serandite, Leucophanite

The finest specimens of both of these species occur at Mont Saint-Hilaire, Quebec, and often together.
Serandite occurs as orange-pink, blocky to elongated crystals that often are the first mineral that people think about when they think of this famous locality.
Leucophanite is a beryllium mineral that usually has a greenish colour or tinge, although it can be colourless. It usually occurs in pegmatites with serandite, microcline, catapleiite, etc.

  • Here is a small but potent specimen! :) It is a part of a pink, serandite crystal with a light green leucophanite crystal attached. The leucophanite crystal is fluorescent! Rare and unusual specimen.

  • This piece shows a couple of light pink serandite crystals embedded in the "back" of a pretty nice analcime specimen. So it is two specimens in one! The serandite crystals are both terminated with the largest one being particularly nice. It has small, clear analcime crystals peppering the sides of it. The smaller serandite crystal has a couple of contact points on the sides. As you can see from the back, the "matrix" for these serandite crystals is a very nice cluster of analcime crystals. As well, there are tufts of acicular, light mauve, yofortierite crystals (as in the attached micro-photo) on the serandite and analcime here and there. Pretty nice!

  • A group of divergent, light pink serandite crystals highly encrusted with fine-grained polylithionite. Significantly, there is a portion of the divergent serandite missing off of the front. The remaining crystals look great! As well, there are a number of very nice tufts of light mauve yofortierite on the serandite. The colour is not right in the micro-photo but they are light mauve and very nice!

There are some rhabdophanes in a couple of openings in the serandite crystals and, of course, the ubiquitous aegirine here and there. Also some tiny purple fluorites on the serandite crystal termination. Displays very well!

  • Several part crystals of deep orange, blocky, serandite crystals are present o nthe top of this large microcline crystal section. There are also small natrolite crystals and a couple of aegirine crystal remains. I think the specimen dcould be improved with air abrasion or judicious picking of grunge off of and from near the crystals. Shows well, as well!

  • A number of sharp, green, pseudo-cubic leucophanite crystals are present on this pseudomorph of birnessite after serandite. The birnessite crystal may, in fact, be serandite just partially altered to birnessite. Hard to say! Interesting, nice specimen of rare minerals no matter what!

  • The matrix for this specimen is a monster microcline crystal1 11.6cm across and 3.0cm thick. The focus of the specimen is a cluster of sharp, white, analcime crystals to 30mm, stocky, fluorescent natrolite crystals to 10mm and colourful, candy-orange serandite crystals to 18mm. The specimen would be WAY more expensive but the serandite crystals are mostly bruised. The dark-red patches on the upper right of the main photograph are rosettes of rhodochrosite crystals. An impressive cabinet specimen!
