Brookite is a Crystal Mineral type that can be found at several localities around the world. Its colors can range from reddish to orange, yellowish, brownish, gray, to black. Brookites found at the Arkansas locality in the United States have a different form than the others, and that variety of Brookite is also known as Arkansite (The left side one in the picture).
(Please note: There are some Rutiles marketed as Brookite in the market today. Rutile may be related to Brookite, but they are not one and the same. Brookite, Rutile, and Anatase are polymorphic forms of Titanium Dioxide – same mineral composition but with different crystallized structures, and Brookite is rarer than both Rutile and Anatase.)
