Graphite habit
WebThe graphite is pushed aside by crystal growth within a rock that is being metamorphosed. As growth occurs, the particles become concentrated at crystal interfaces. The result can be a cross-shaped pattern within the mineral - similar to the "cross-stone" shown in the accompanying photo.

WebIt enables one to be more present in the physical body and conscious of Nature and ones surroundings. It encourages one to celebrate moments of isolation to absorb, reflect, and connect with these energies and enkindles an awareness of the spiritual connection we hold with all living things. WebIn graphite, carbon atoms are contained in layers in a hexagonal pattern where the covalent bonds are shorter (and thus even stronger) than those of diamond. However, each layer is connected to the other with a longer and much weaker van der Waals bond. This gives graphite a single direction of cleavage, parallel to the basal pinacoid.
