Quartz crystals have a unique property of being piezoelectric, meaning they generate an electric charge when subjected to mechanical stress. This property allows them to be used in various electronic applications, such as:

* Oscillators: Quartz crystals can be used to generate precise frequencies, making them essential components in clocks, watches, computers, and other electronic devices.

* Filters: Quartz crystals can be used to filter specific frequencies, making them useful in radio receivers and other communication devices.

* Sensors: Quartz crystals can be used to detect changes in pressure, temperature, or other physical parameters.

So, while quartz is found in many different electronic devices, it is the quartz crystal that is specifically made from the mineral quartz.
