Granite is a very hard, crystalline igneous rock that is mainly composed of quartz. It is not a colloid but a heterogeneous mixture.
What is a very hard native crystalline carbon valued as a gem?
Diamond is a very hard native crystalline carbon valued as a gem
Is rock a crystalline solid?
no but there is such a thing of a rock crystal. does that make sense?
Are all sedimentary rocks hard?
Hardness in a rock has different meanings. Although sandstone, a sedimentary rock, may be composed of quartz grains (relatively hard on the Mohs scale of mineral hardness), it might be loosely cemented by calcite crystals which are not so hard, making it crushable by the squeeze of a hand. There are other well cemented sedimentary rock types that are very resistant to breaking, however. Certain limestones, breccias, conglomerates, and sandstones take great effort to break into smaller pieces. In general though, geologists will refer to sedimentary rock as soft rock, and igneous rock as hard rock. Igneous rock has an interconnected crystalline structure which makes it very resistant to fracture.

Slayer are a thrash metal band that rock very, very, very hard. So if you rock like Slayer, you rock very, very, very hard.
What is the difference between a crystalline rock and a clastic rock?
Crystalline rock is composed of interlocking crystalline grains, as in granite. Clastic rock is composed of rock or mineral grains which have become cemented together by the processes of lithification. Examples of clastic rock are sandstone and conglomerate.
