Diaphaneity is opaque.
Crystal System is amorphous or monoclinic; (?).
Crystal Habits include resinous masses with poorly defined
Cleavage is not apparent.
Fracture is conchoidal.
Hardness is 3 – 3.5
Specific Gravity is approximately 2.3+ g/cm
Streak is a little lighter in color than the specimen itself.
Associated Minerals include neotocite.
Distinguishing Features: Crystal habit.
