What is tourmalinated quartz?

Tourmalinated quartz is a specific variety of quartz that contains needle-like or rod-like inclusions of tourmaline within its crystal structure. These inclusions are often dark, typically black, and create a striking visual effect against the usually lighter background of the quartz. The presence of these tourmaline inclusions is what distinguishes tourmalinated quartz from other types of quartz. This unique combination not only enhances the aesthetic appeal of the stone but can also influence its metaphysical properties, providing a connection to both quartz and tourmaline's characteristics.

The other options describe different properties or treatments of quartz but do not correctly define tourmalinated quartz itself. For instance, clarity relates to the transparency and purity of the stone, while treatments affect color but do not involve inclusions. Lastly, specific patterns of bands are indicative of other types of quartz rather than the tourmaline inclusions characteristic of tourmalinated quartz.
