When quartz crystals contain tiny bubbles or liquid-filled fissures, they can produce a rainbow effect through light interference, making them suitable for exquisite jewelry. Empress Josephine, Napoleon's wife, possessed a dazzling collection of gems, including jewelry made from rainbow quartz.
Quartz, due to various impurities, exhibits a wide range of colors and includes the following varieties:
Rock crystal: colorless and transparent
Amethyst: purple, transparent or translucent; its color can be removed by heating.
Rose quartz: light rose color, dense and translucent.
Smoky quartz: brown or brownish transparent variety. Its color is caused by radiation, where Si is replaced by Al, leading to a lack of paramagnetic centers in the tetrahedron. Further deepening of color results in black quartz (morion).
Citrine: golden or lemon yellow
