Okenite is composed of calcium (Ca), silicon (Si), oxygen (O), and water (H₂O). Its structure is based on the silicate framework, with interlaced fibers of calcium silicate. Okenite is typically found in white, and it does not form typical crystals but instead occurs in fibrous, hair-like formations that often resemble cotton-like masses or tufts.It is not commonly used in industrial applications due to its softness but remains highly prized in mineral collections due to its rarity and aesthetic appeal.
