Crystalnoun

(countable) A solid composed of an array of atoms or molecules possessing long-range order and arranged in a pattern which is periodic in three dimensions.

Quartznoun

(mineral) The most abundant mineral on the earth's surface, of chemical composition silicon dioxide, SiO2. It occurs in a variety of forms, both crystalline and amorphous. Found in every environment.

Crystalnoun

(countable) A piece of glimmering, shining mineral resembling ice or glass.

Quartznoun

A form of silica, or silicon dioxide (SiO2), occurring in hexagonal crystals, which are commonly colorless and transparent, but sometimes also yellow, brown, purple, green, and of other colors; also in cryptocrystalline massive forms varying in color and degree of transparency, being sometimes opaque.

Crystalnoun

(uncountable) A fine type of glassware, or the material used to make it.

Quartznoun

Crystalnoun

Crystal meth: methamphetamine hydrochloride.

Quartznoun

a hard glossy mineral consisting of silicon dioxide in crystal form; present in most rocks (especially sandstone and granite); yellow sand is quartz with iron oxide impurities

Crystalnoun

The glass over the dial of a watch case.

Quartz

Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The atoms are linked in a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2.

Crystaladjective

Very clear.

‘"Do I make myself clear?" / "Crystal."’;

Crystalnoun

The regular form which a substance tends to assume in solidifying, through the inherent power of cohesive attraction. It is bounded by plane surfaces, symmetrically arranged, and each species of crystal has fixed axial ratios. See Crystallization.

Crystalnoun

The material of quartz, in crystallization transparent or nearly so, and either colorless or slightly tinged with gray, or the like; - called also rock crystal. Ornamental vessels are made of it. Cf. Smoky quartz, Pebble; also Brazilian pebble, under Brazilian.

Crystalnoun

A species of glass, more perfect in its composition and manufacture than common glass, and often cut into ornamental forms. See Flint glass.

Crystalnoun

The glass over the dial of a watch case.

Crystal

A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations.
