Well, I remember when i was a child, i used to take water and sugar and mix it in a jar, then i would tie a peice of string around a stick then place the stick horizontally over the top of the jar, and let the string dangle into the sugar water. After the watter evaporated there would be sugar crystals. I'm not sure if this will work but its worth a try! :) Hope this helps!
Large crystals found in a fine-grained rock can indicate that the rock cooled slowly, allowing the crystals to grow larger. This slow cooling process typically occurs deeper within the Earth's crust where temperatures are higher. The presence of large crystals in a fine-grained rock can also suggest that the rock underwent metamorphism, changing its original composition.
Crystal size in these rock types is determined by their rate of cooling. Pegmatites have large crystals due to very slow cooling. Obsidian has microscopic crystals due to almost instantaneous cooling.
The texture of andesite, characterized by large crystals set in a fine-grained matrix, is called porphyritic. This texture indicates that the rock underwent two stages of cooling: the larger crystals formed from slow cooling beneath the surface, while the fine-grained minerals crystallized quickly during subsequent rapid cooling. This combination gives andesite its distinctive appearance.
Very fine crystals can easily clump together, affecting the texture and consistency of a product. Additionally, fine crystals can dissolve too quickly, leading to a sudden release of flavor or sweetness that may be overpowering. Fine crystals can also cause issues with product stability and shelf life.
Large crystals in igneous rocks usually form when the magma cools slowly underground, allowing the crystals more time to grow. The composition of the magma, the cooling rate, and the amount of available space for crystal growth all play a role in determining the size of crystals in the rock. Rapid cooling at the Earth's surface typically results in the formation of fine-grained rocks.
Large crystals of coarse sea salt have a smaller surface area exposed to the water compared to fine table salt, which leads to slower dissolution. The smaller surface area of coarse salt slows down the rate at which water molecules can break down the salt crystals and dissolve them completely.

The size of crystals in an igneous rock is called texture. Texture can range from fine-grained (small crystals) to coarse-grained (large crystals).

There are numerous physical properties of table sugar. Some of these include being colorless, odorless, fine, sweet tasting, and a type of powder that contains crystals.
Fine grained has larger crystals and coarse grained has smaller crystals

Porphyry cooled slowly, allowing large crystals to form within a fine-grained matrix. This slow cooling process gives porphyry its characteristic appearance of large crystals embedded in a finer grained groundmass.

Rarity is relative. My experience and a quick perusal of mindat.org would suggest that jarosite is not very rare. (There are many hundreds of localities, and fine micro crystals can be easily purchased for a few bucks.) However, jarosite is indeed rare in large crystals or fine specimens of display quality.
