Quartz

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.
[1913 Webster]
Note: The crystalline varieties include: amethyst, violet;
citrine and false topaz, pale yellow; rock crystal,
transparent and colorless or nearly so; rose quartz,

crypto-crystalline varieties are: agate, a chalcedony
in layers or clouded with different colors, including
the onyx and sardonyx; carnelian and sard, red or
flesh-colored chalcedony; chalcedony, nearly white, and
waxy in luster; chrysoprase, an apple-green chalcedony;

ages. It forms the rocks quartzite (quartz rock) and
sandstone, and makes most of the sand of the seashore.
