Anatase

Anatase is a striking and rare mineral form of titanium dioxide (TiO₂), prized by collectors for its unique crystal structure and eye-catching colors. It commonly occurs as small, well-formed crystals, often pyramidal in shape, which give it a distinct, almost architectural appearance. Anatase crystals can display an impressive range of colors, from deep indigo-blue to rich shades of brown and even golden yellow, depending on impurities within the crystal lattice.
