Quartz can be identified by:
1. Luster: nonmetallic
2. Hardness: 7
3. Streak: white
4. Color: usually colorless, white or gray but can be varieties of all colors
5. Cleavage: none
6. Crystal habit: hexagonal prisms and pyramids
7. Specific Gravity: 2.6-2.7
Visually, if crystals are present. The quartz crystal is six sided, terminated with a six sided pyramid.
