A quartzite.
instrusive Rock
A rock with large crystals typically has a coarse texture. The large crystals are easily visible and may feel rough to the touch due to their size.
The texture depends on the size and shape of the crystals you see in it. The larger the crystals, the slower the rate of cooling. This suggests that it is an intrusive rock. Smaller crystals suggest more rapid cooling indicating that it is an extrusive rock. INTRUSIVE- cooled inside the earth and had more time to create crystals EXTRUSIVE- cooled on the surface of the earth and created small crystals
Completely molten rock would not contain any crystals. Most magmas, however, are a mixture of molten and solid crystals of some sort. It is possible that a magma could contain larger crystals of a specific mineral.
Rock salt typically has a coarse and granular texture. It is composed of large, irregular-shaped crystals that easily break apart when crushed.
Min. A $1.00 A Lb. Depending on what kind of crystal is in the geode, amythyst, chalcedony, ect... Find out what kind(s) of crystal are in it first.

Igneous rocks typically contain crystals within their structure.
Intrusive or granite.
Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.
The rock with crystals inside in can be igneous rock, but no, idk about the minerals.
The crystals in a rock are often referred to as mineral crystals. They are formed as the molten rock cools and solidifies, allowing minerals to crystallize and grow within the rock. The size, shape, and arrangement of these crystals can provide clues about the rock's formation and history.
Geodes are rocks that are lined or filled with crystals. Pegmatites are rock formations that often exhibit extremely large crystals. Just a note--all rocks are composed of mineral crystals, with few exceptions. The crystals in some, however are just too small to see.
Crystals are about 12 dollars.
