Raw and polished quartz crystals in various formations. Individually chosen, carefully photographed.
In its purest form, the mineral quartz is colourless and transparent. Inclusions, such as tiny bubbles, other minerals, or fractures can cause the crystal to become translucent.
Colourless quartz that's transparent or translucent is also known as rock crystal.
The colour in varieties such as rose quartz, chrysoprase, and amethyst comes from trace elements or
inclusions of other minerals, which affect the crystal's appearance.
Quartz, one of Earth's most abundant minerals, can be found in almost every geological environment.
