In the year 2k, I classified Cumberlandite into 3 different types:
- Monotonous Cumberlandite-Shows no white plagioclase crystals. The most common type.
- Ornament Cumberlandite- Shows a few or many white plagioclase crystals. Very rare type.
3. Tenuous Cumberlandite- Shows a greenish colored plagioclase crystals. Extremely rare type.
