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.
Generally a high presence of quartz suggests a "mature" rock, since it indicates the rock has been heavily reworked and quartz was the primary mineral that endured heavy weathering. 47 While the majority of quartz crystallizes from molten magma , quartz also chemically precipitates from hot hydrothermal veins as gangue , sometimes with ore minerals like gold, silver and copper.
