Chrome dravite is a chromium-bearing variety of tourmaline belonging to the dravite subgroup, typically recognized by its green to brown coloration. Its general chemical composition is NaMg₃(Al₆Si₆O₁₈)(BO₃)₃(OH)₃OH, with chromium substituting for part of the aluminum. Besides Pakistan, notable deposits of chrome dravite are found in Tanzania, Madagascar, Austria, and Russia. This chromium-rich variety is often prized for its vibrant green tones, distinct from the more common brown dravite.
For collectors, this specimen stands out as a rare and aesthetic chrome dravite tourmaline, combining both color intensity and matrix presentation. Its terminated crystalline form and chromium-rich character make it a desirable addition to any fine mineral collection.
