Specimen dimensions: N/A, grains of mineral, use centimeter scale
Specimen weight: ⅛ ounces (5 grams)
Collection: Northridge Campus
For reference: photo centimeter scale.
Distinguishing Physical Properties:
These are small grains, as poured out of a specimen jar.
The first thing that I notice is the vitreous, or glassy luster (it looks like green glass) and the distinct yellow-green (or "olive") color.
The only other property that I discern, there is not any evident cleavage - all the glassy surfaces look irregular, or conchoidal.
