Calcite: What colors can it come in? What is its luster? Is all calcite smooth and cube shaped?
I know the luster is mostly vitreous (glassy) and transparent/translucent, but can it come in any other lusters, or shapes?
<3Thanks [:
Calcite is usually white, less commonly clear. But it also can be pretty much any color due to small amounts of ‘contaminants’ staining it. Because it can twin and often grows to fill confined areas its outward or gross shape can be almost anything, and cryptocrystalline calcite an mimic many other minerals. It is very common to mistake less common shapes and colors of calcite for other things. Its luster is also very variable, waxy and greasy are common. ANd because it is soft its luster can change from one side of a crystal to another.
But it is always the same hardness, 3 on the Moh’s scale, and it is always vulnerable to dilute hydrochloric acid- but sometimes you have to rough up the surface to get a clean part of the calcite to put on the acid, it often has a sort of case hardened effect from reacting with things in contact or carried by water solution.
Every field geologist has embarrassed himself by failing to identify this common and well known mineral.
