Granite: Granite is a complex stone that comes in various colors. Interestingly, it's a coarse-grained, Quartz-rich igneous rock. Auriferous Granite often contains gold-bearing Quartz veins, which miners seek out because of their higher gold content. Slate: Gold can become deposited in Slate's thin cracks and faults over time.

Granite is much harder than gold, but it's far less valuable than gold. Precious metals like gold and silver are softer than most of the items you'll find rockhounding and their more malleable nature can help you set them apart from similar rocks. In 1822, Friedrich Mohs developed a scale to measure a rock's hardness.
