About Cancrinite
Cancrinite is a yellow to orange, pink, or colorless feldspathoid mineral that forms massive to granular aggregates in alkali-rich igneous rocks such as nepheline syenites. Named after Russian statesman Georg von Cancrin, it is found in notable occurrences in Ontario (Canada), Norway, and Russia. Bright yellow to orange massive material is occasionally polished as a lapidary curiosity, though faceted gems are rarely encountered.
