To follow are some of the less common and rare minerals from the thumbnail collection of Marcelle Weber.  This grouping was acquired by Dr. Steve Chamberlain and the ones being sold below are the finest from Mt. St-Hilaire, Québec, Canada (and a few other localitites).  With the removal of collector access several years ago to the Mt-St-Hilaire quarries rarities like these have become even more difficult to get.
