Celestine

Orange celestine is an exceptionally rare and unusual variety, sourced from an urban occurrence in southern Ontario. The creamy orange hue is believed to be a result from trace amounts of copper impurities within the crystal structure. Globally, occurrences of orange celestine are virtually unknown, making this locality one of the only accessible sources. This particular specimen, a chunk of dolostone featuring vibrant orange celestine, shows minor damage but stands out as one of the better examples due to its defined crystal faces—an uncommon feature, as this variety typically occurs in massive, crystalline aggregates. Most known occurrences of this rare variety have been documented near Caledon, specifically from a rock cut along an old rail spur line, making specimens from this locality increasingly difficult to obtain.
