Transparency crystals are transparent to translucent. Equant crystals that appear stubby and bead-like are also common. The crystals are sometimes flattened and can appear bladed. The terminations are either blunted or steeply pyramidal. Also massive, lamellar and granular habits are found.
Cleavage is perfect in one direction and distinct in another.
Fracture is uneven. Streak is white. Associated Minerals are calcite , celestite , borax , ulexite , kernite , hydroboracite and other borate minerals. Best Field Indicators are crystal habit, associations, locality, density, cleavage and hardness.
