| | Description | |
| Comments: | Probably the best analcime specimens I have ever seen have been from St Hilaire. Some crystals are about 15 cm in diameter and often associated with other interesting minerals like aegirine and serandite. Specimens that have interesting associations are always more appreciated by collectors. Pseudomorphs of cancrinite or burbankite(?) to 25cm. Formed in zoned pockets up to 1.3 by 2.6 meters. | | Habit: | Trapezohedra up to 25cm across | | Colour: | Transparent colorless to opaque white or gray in larger crystals | | Quality of samples: | Excellent - world class for species or very significant. (!!) | | Rarity at site: | Common | | Confirmation | |
