This section of our website mainly features quartz with inclusions.
You'll also find varieties with their own name that are not quite as well known.
Although inclusions in quartz are relatively common, the two most popular varieties are rutilated quartz and tourmalinated quartz.
During the early formation of a quartz crystal various minerals or substances can become trapped. As the crystal grows these materials become inclusions.
Inclusions can also be water, petroleum or gas.
When present in abundance in colourless quartz inclusions can change the colour of the crystal.
Inclusions can also create interesting patterns and optical phenomena.
The fibrous inclusions in tigers eye create chatoyance. Optical phenomena in other varieties includes aventurescence, schiller and asterism.
