Picard holding his crystal

A crystal was a regularly-ordered solid mineral.

One notable material occurring in crystal form was dilithium. Crystals were also key components of various Federation technologies, such as the linear memory crystal in computer cores, discharge crystals used in phaser rifles, and emitter crystals used in Subspace transceivers.

In the Earth comedy movie The Court Jester, the chalice with the palace was made out of crystal. (ENT: "Doctor's Orders")

Orientine acid was capable of burning through nearly anything except the crystal that made up the vial it was housed in. (TAS: "The Survivor")

The surface of the planet Terra 10 was described as crystalline. (TAS: "The Terratin Incident")

A quote claimed that sculptures were crystallized spirituality. In 2256, Michael Burnham recalled the quote but not who said it. (DIS: "The Vulcan Hello")

Data experimented with producing vibrations in a crystal by means of graviton pulses, which Doctor Kila Marr later compared with tapping a crystal goblet. This technology was implemented to make contact with the Crystalline Entity and was later used by Dr. Marr to kill the creature. (TNG: "Silicon Avatar")

Captain Jean-Luc Picard kept a small transparent crystal on the desk in his ready room aboard the USS Enterprise-D. He often played with the small stone when he had to make an important decision. (TNG: "Conspiracy", "Where Silence Has Lease", "Suddenly Human", "A Matter of Time", "The Masterpiece Society", "Conundrum"; Star Trek Generations) His first officer, William T. Riker, also did so on occasion. (TNG: "Gambit, Part I")

Crystals were an important part of Gelrakian culture, likely to the abundance of crystals on their homeworld. They had spears with crystals, crystal graffiti, and they even planned on building a race car made of crystal. (LD: "Temporal Edict")
