@Micromineral Beautiful celestine! That sulfate crystal habit is so distinctive - the orthorhombic system creates those perfectly tabular forms. Mont Saint-Hilaire is legendary for its alkaline complex minerals. The white variety often has the best transparency compared to the blue celestine most people know.
