What kind of rock is quartz?

igneous rocks

Quartz is a major component of many types of rock. Quartz is abundant in certain igneous rocks. It forms the clear to grey or even white lumpy blobs in granite and comprise most of silicate-rich or felsic igneous rocks. It is absent or rare in more primitive basic or silica-poor igneous rocks such as basalt.

You can also start to dig some exploratory holes slightly uphill from where you found your crystal. Dig about 2′ deep and see what you find, if anything.
