Actually, The Ancient Mesopotamians created crystals in about 2,547 B.C. They offered them to their gods.

The texture depends on the size and shape of the crystals you see in it. The larger the crystals, the slower the rate of cooling. This suggests that it is an intrusive rock. Smaller crystals suggest more rapid cooling indicating that it is an extrusive rock. INTRUSIVE- cooled inside the earth and had more time to create crystals EXTRUSIVE- cooled on the surface of the earth and created small crystals
Porphyritic texture is a type of rock texture characterized by large crystals (phenocrysts) embedded in a finer-grained matrix (groundmass). It is created when magma cools at different rates, resulting in the formation of larger crystals early in the cooling process (phenocrysts) followed by the growth of smaller crystals around them (groundmass).
It has to do with the shape molecular formula of the compound that it is created from.
Crystals are solid materials whose atoms are arranged in a highly ordered, repeating pattern. While many crystals are minerals, not all crystals qualify as minerals; for a substance to be classified as a mineral, it must be naturally occurring, inorganic, solid, and have a defined chemical composition. Examples of mineral crystals include quartz and feldspar, while synthetic crystals, like those created in labs, do not meet the criteria for being classified as minerals.
Ghost Crystals are crystals of crosslinked polyacrylamide.
NO CRYSTALS are not living!!!!!!!!!!!!!!!!!
