dusted77 on Instagram: "Did you know that one of the rarest colors of tourmaline is no color? Known as Achroite tourmaline, it gets its name from the Greek word “άχρωμος” or achroos which means without color. Most tourmalines get their vibrant colors from trace impurities that are absent in achroite, making truly colorless examples scarce and prized by collectors. It requires very pure conditions, free of elements like iron, manganese, and chromium, which typically create coloring in tourmaline.
