Graphite Crystals
Lamellar Crystals in Marble Matrix
Sweden
Diagnostic Features
Hardness: 1
Streak: Black to silvery gray
Specific Gravity: 3.1
Luster: Metallic (silvery)
Cleavage: 1 direction (weak platy)
Fracture: None
Other: Graphite is one of the softest of minerals,
and easily rubs off on the fingers leaving a blackish
gray residue which resemble pencil markings. It has
a distinctly "greasy" feel when rubbed and is very
friable.
Identification Tips
1. The silvery grey luster, slippery, greasy feel and extreme softness are characteristic features of graphite.
2. Graphite will leave a visible mark when rubbed against paper and will not in turn abrade the paper surface whatsoever.
3. Graphite is frequently found in association with marbles and other types of metamorphic rocks.
4. Next to talc, graphite is the softest common mineral you are likely to encounter.
