Conchoidal - Fractures developed in brittle materials characterized by smoothly curving surfaces, (e.g. quartz).
Habit:
Aggregates - Made of numerous individual crystals or clusters.
Habit:
Cryptocrystalline - Occurs as crystals too small to distinguish with the naked eye.
Habit:
Earthy - Dull, clay-like texture with no visible crystalline affinities, (e.g. howlite).
Hardness:
1-2 - Between Talc and Gypsum
Luster:
Vitreous (Glassy)
Streak:
yellowish white
Optical Properties of Parascorodite
Gladstone-Dale:
