they are put together and squated
Im learning this in school, and the answer is look for a "rock cycle" and that answers all questions like yours :)
Foliated metamorphic rocks have a layered or banded appearance due to alignment of mineral grains, exhibit strong cleavage, and are formed under directed pressure. Non-foliated metamorphic rocks do not have a layered structure, show more equidimensional mineral grains, lack cleavage, and are typically formed under contact metamorphism.
Understand that metamorphic rocks are those that have changed in some way by heat or pressure or both. Sedimentary rocks are formed from sediments and igneous rocks are formed by fire. When these rocks change again, they become metamorphic. Marble is one type of metamorphic rock.Look at the way the grain are formed. In schist rocks, you can see that the layers and the grains all go the same way. Warning Metamorphic rocks are difficult to classify because different amounts of heat or pressure to the same rock can look different.
Collect some big rocks from backyards, parks, sidewalks anywhere were you can find rocks. Have a hammer and gently pound on the rock several times until it cracks open. If crystals or gems fall out, be proud and keep them. If they don't, no crystals. NOTE: Don't use the rocks that you can buy from HomeDepo for decoration because they DO NOT work!! No gems or crystals will fall out!!!

Those are two types of metamorphic rocks. Banded metamorphic rocks are when rocks layer into layers and they look like strips or Bands. Non banded is the opposite of banded
The minerals which appear are quite similar chemically but not physically. In metamorphic rocks, foliation can be seen-bands of rocks formed by great pressure, whereas in igneous rocks, this is never present because igneous rocks specifically need to have just previously melted, so therefore, these bands are disorganized and lost. Therefore, igneous rocks clearly don't seem to have any patterns unlike metamorphic rocks. Also, some minerals only form during metamorphism/melting+cooling. Therefore, the chemical composition is usually slightly different. E.g. Garnet is only formed under high-grade metamorphism-high temperatures and pressures. Also, the crystals sizes in igneous rocks depend on how long the rock has had to cool. So therefore, an igneous rock's crystals could be a lot bigger or smaller than a metamorphic rock's crystals. But then again, both rocks have interlocking crystals unlike sedimentary rocks, so in that way, at first glance, they can sometimes look very similar, (depending if it is intrusive of extrusive-metamorphic rocks will look a lot more like intrusive igneous rocks because of how the air affects the magma, (how magma looks when it cools), extrusive rocks look different, (blacker, smaller crystals etcetera).

Sometimes, but not always!
Out of the ground they look like little rocks/crystals. It is only when they are cut and polished that they look like they do in a ring.

Because thay are both Metamorphic rocks :-)
Hornblende is a dark-colored mineral belonging to the amphibole group. It typically appears as long, black or dark green prismatic crystals with cleavage angles at nearly 60 or 120 degrees. It has a glassy to dull luster and can be found in a variety of igneous and metamorphic rocks.
There are many types of rocks and they do not all look alike. Colors vary. Some have more than one color, like granite or marble that can have many colors. Some are smooth, like those that have been in a river for a while and have had the rough edges worn off, and some are jagged. Rocks come in all shapes and sizes.
