Mar 26, 2018 To identify gold inside of a piece of quartz, hold a magnet against the rock. If the quartz sticks to the magnet, then it contains iron pyrite, or fool’s gold. You can also try to scratch a piece of glass or unglazed ceramic with the gold portion of the rock. Real gold will not scratch these substances.

Gold is found widely diffused in nature even though it is one of the scarcer metals. Very commonly, gold occurs as the native metal encased within quartz. Sometimes the gold is in a finely divided state, sometimes in particles of considerable size, as nuggets, grains, scales, plates, threads and wires in quartz rock.

Indeed, while gold deposits have been found in the past in the quartz components of granite, the rock boasts a too-polished surface to act as an effective gold trap. Alternatively, formations such as irregular bedrocks and crevices, as well as minerals like quartz, can be more useful in identifying gold deposits and eventual pay streaks.
