What is a shiny rock called?

Schist is a metamorphic rock that contains flakes of mica. Schist can originate as a sedimentary rock or igneous rock. Large crystals cause schist rocks to reflect lots of light which gives it a very shiny appearance.

What type of rock is sparkly?

Mica minerals make some rocks sparkle! They are often found in igneous rocks such as granite and metamorphic rocks such as schist. They sparkle because light is reflected on their flat surfaces, which are where the mineral breaks along its plane of cleavage.

What stones look like metal?

What Is Hematite? Hematite is a crystal made of iron oxide and is an important iron ore. The stone often looks like it is metallic because of the iron content and the shine that comes with that. The most common color is black for this stone.

What is a shiny rock like diamond?

What rocks are smooth and shiny?

Igneous Rock
