Intrusive igneous
Crystals will not grow if buried in the ground. For crystals to grow, specific conditions are required such as a solution of dissolved minerals, the right temperature, and time. Burial in the ground won't provide these conditions for crystal growth.
Rocks with small crystals form above ground, because when formed under ground the magma makes the rock cool slower causing more time for the crystals to grow. Above ground the rock cools faster, because the air isn't as hot under ground than above ground.
You can find crystals, meaning rocks and minerals in their natural crystal form (they grow that way), almost anywhere in nature - both on the ground and under the ground. Most crystals are mined, since many have formed millions of years ago. Check out rockhounding sites if you want to mine your own, but the easiest way to find crystals is to go to a rock shop or metaphysical store in your area. You can find them on line, but it is not the same as actually touching them in order to get to know what you are looking at. See also the link below.
Igneous rocks are formed from the solidification of lava or magma . When an igneous rock cools and hardens above ground, it cools quickly, resulting in a little to no grained rock. This is called an extrusive rock. An example of an extrusive rock is obsidian. When an igneous rock forms below ground, it cools slowly, resulting in a well developed mineral composition, with large crystals. Granite is an example of an intrusiveigneous rock.
Yes. And the size of crystals depend on the time taken to crystallize.

Mineral crystals.
Basalt is formed from volcanic lava flows that cool quickly on the Earth's surface, while gabbro is formed from the slow cooling of magma deep underground. Both rocks contain similar mineral compositions, with basalt having fine-grained crystals and gabbro having coarse-grained crystals.
Crystals formed from lava that solidifies above ground are typically smaller due to the faster cooling process, resulting in fine-grained rocks like basalt. Crystals formed underground from slower cooling have more time to grow and can develop larger sizes, leading to coarse-grained rocks like granite. The cooling rate affects crystal size and the overall texture of the rock.
Plutonic rock tends to have large crystals because it solidifies deep underground, where the overlying material insulates it so that it cools slowly, allowing time for large crystals to form. Volcanic rock tends to have small crystals (or to be amorphous) because it solidifies above ground, where air and water can cool it quickly by convection. Rapid cooling does not allow time for crystals to grow large. Plastic rock I don't know about.
crystallization above ground and crystallization below ground
Pegmatites are coarse-grained igneous rocks that often contain gem-quality crystals of minerals such as beryl and tourmaline. They also have high concentrations of relatively rare elements like lithium, boron, and beryllium due to their unique mineral composition and formation process in the Earth's crust.
Igneous rocks like rhyolite or andesite are formed when magma undergoes crystallization above ground. These rocks cool relatively quickly, resulting in smaller mineral crystals compared to rocks formed from magma crystallizing deep underground.
A "Desert Rose" is not a living organism, it is a formation of gypsum crystals that form in desert regions where there are mineral(salt) rich ground waters evaporating near the ground surface.

I dont know but if your tlaking about fights then they will break up. Hopefully they won't.
Yes crystals do grow under the ground.
