Is this too much Dear Carrie
I was really nervous to tell you this last week so I wrote you this letter, But you are a kind and simply beautiful person and whenever I see you my heart stops and it's like I'm looking at an angel, If you would like to go out sometime I would love to get to know you better. Btw this is Jacob

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
