Recrystallization is a process in which rocks actually change. It is whereby the crystals of one mineral slowly convert to few but larger crystals of the same mineral with out melting the rock. It is them followed the the process of neomorphism then metasomatism.2.Crystallization is the (natural or artificial) process of formation of solid crystals from a homogeneous solution or melt, or more rarely directly from a gas. This process is often used as a technique to separate a solute from a liquid solution, bringing it into a pure crystalline phase.
pegmatite
it is as i think a physical change
Recrystallization.
It is a change of state and therefore a physical change.

The Aztecs used obsidian, a volcanic glass, to craft weapons, tools, and decorative items. They would mine the raw obsidian from deposits, shape it using specialized techniques, and then create finished products like blades, mirrors, and masks through polishing and crafting methods. This skilled craftsmanship of transforming obsidian into various useful and aesthetic objects played a significant role in Aztec society.
Air, water, and impurities can change the color of a mineral.
Diamonds are formed in a crystalline structure from carbon. Not all crystals are formed from carbon; not all crystals are diamonds.
Besides air and water, there are several things that can change the color of a mineral. Impurities, age, the sun, heat, and pressure can change the color of a mineral.
Yes, they can "grow".
Yes, they can "grow".
The color of crystals will change after heating because of loss of water..
It is a physical change (sublimation).
pegmatite
irreversible
Yes! If the supply of or demand for that mineral changes.
