well technically the first diamonds were made from magma before the earth was populated with people, but now the only way to make crystals(not diamonds) is from burning graphite, which is the only other substance completely made from carbon, like diamonds. so yes technically crystals are made from magma when it is spewed up from volcanos.
What else can I help you with?
What are the similarities between sedimentary rocks and metamorphic rocks?
They are both rocks
What are metamorphic rocks with banded layers called?
Gneiss
Metamorphic rocks that show layers of dark minerals alternating with layers of light minerals are classified as?
foliated metamorphic rocks. The alternating layers are caused by the alignment and segregation of minerals during the metamorphic process, resulting in a banded or layered appearance. Examples of foliated metamorphic rocks include gneiss, schist, and slate.
Metamorphic rocks that do not have distinct layers or bands?
non-foliated.
When rock fragments get compressed and hardened to form layers of rocks they are known as?
metamorphic rocks
What are foliated metamorphic rocks?
Foliated rocks have layers in them. We often refer to the layers as Banding.
What are the similarities between sedimentary rocks and metamorphic rocks?

Does metamorphic rock have layers?
Not exactly. Some metamorphic rocks have foliation, which can appear similar to the layers of sedimentary rock. Foliation develops from mineral grains being oriented by pressure, rather than the deposition of layers.
What are metamorphic rocks without layers called?
gneiss
What metamorphic rocks that don't have layers?
non-foliated.

Are igneous rocks made when layers of weathered rocks or soil is compacted?
No that is a metamorphic rock
