Rubellite gemstone with an insane color

Tourmalines are a group of minerals belonging to the silicate class, in the order of cyclosilicates. The name derives from the Sinhalese turmali, which literally means “mixed package,” i.e., a stone of various colors, and formerly indicated the name of the crystals brought to Europe from Ceylon. The crystal belongs to the trigonal system, is prism-shaped, very elongated, vertically striped, and sometimes with unequal development at the two ends of the vertical axis. Its color depends on its chemical composition and may not be uniform throughout the crystal.
