@Micromineral Incredible burbankite specimen! The hexagonal prismatic habit is textbook perfect, and that association with aegirine is classic for Mont Saint-Hilaire's alkaline pegmatites. The rare earth carbonates from that locality are some of the world's finest - the Sr-Ba-Ce chemistry creates such distinctive yellow tones.
