Virtually all rock contains mineral crystals of various sizes. Most volcanic rocks such as granite contain crystals of quartz and other minerals. Crystal size varies depending on the speed of cooling.
The pressure required to crush a crystal depends on its composition and structure. In general, crystals have high compressive strengths, so it would take a significant amount of force to crush them. The specific weight needed would vary based on the type of crystal and its size.
Ice is a type of solid crystal with a hydrogen bond structure. The bonds between water molecules in ice are hydrogen bonds which are weaker than covalent or ionic bonds. The crystal structure of ice is hexagonal.
A doped germanium crystal with an excess of free holes is called a p-type semiconductor. In this type of semiconductor, the majority charge carriers are positively charged "holes" created by introducing acceptor impurities into the crystal lattice.
The element that gives emeralds their beautiful green color is the same element that turns corundum into red rubies. Red Rubies and emeralds are like twins but not the same color. ITS A CRYSTAL

any type of rock is a crystal it might not be scientific though....
Quartz
A clear type of quartz is known as rock crystal. It is a colorless variety of quartz that is transparent and often used in jewelry and crystal healing practices.
Rock crystal.
The appearance and type of mineral crystal appearing in a rock is dependent on the type of rock and the method by which it is created.
Rock crystal
No. A crystal is the solid form of a mineral. Mineral crystals are present in nearly every rock, regardless of type.
Fine crystal grain.
fine
Small crystal grains form from rapid cooling of magma resulting in an aphanitic rock texture.
Large crystals with a coarse crystal grain texture.
It is mineral
