Schorl is the iron-rich end member of tourmaline, usually forming elongated, prismatic crystals with a black to deep brown color and a bright to submetallic luster. The mineral often occurs in pegmatites and hydrothermal veins, and may display triangular cross-sections or a stepped habit typical of tourmalines. In polished specimens, Schorl can reveal a subtle greenish attenuation along crystal faces, and inclusion-rich varieties may show striking internal zoning.

Notable localities for Schorl include Namibian and Brazilian pegmatites, as well as deposits in the United States and Mexico, where robust, well-formed crystals are collected from coarse-grained pockets. The stone is prized in rock and mineral collections for its dramatic contrast against lighter minerals and its classic, jet-black appearance, which pairs well with metallic or silicate specimens. For collectors, Schorl offers a reliable, recognizable specimen type with abundant material, attractive crystallization, and a broad range of sizes suitable for display or study.
