Color is usually colorless, white or pale shades of yellow, blue, pink or rose. Luster is vitreous. Specimens are transparent to translucent.
Cleavage is good in two directions.
Fracture is conchoidal. Hardness is 4.5 - 5. Streak is white. Associated Minerals include andalusite , lithiophilite and triphylite and other phosphates. Best Field Indicators are crystal habit, color, associations, localities and cleavage.
