Most of the time, the gold is like tiny glittery specks inside the quartz, making it a fun but challenging treasure to find. The value of the gold found in quartz depends heavily on the amount of gold present. Some specimens boast visible, concentrated gold veins, making them valuable collector's pieces or even commercially viable for extraction.

Gold deposits are formed via a very wide variety of geological processes. Deposits are classified as primary, alluvial or placerdeposits, or residual or laterite deposits. Often a deposit will contain a mixture of all three types of ore. Figure 1. High-grade (bonanza) gold ore, brecciated quartz-adularia rhyolite.

Rock with native gold provided by Weinrich Minerals. The streak test is a way to identify minerals, including gold, by rubbing them on an unglazed ceramic tile and observing the color of the streak they leave. Gold will leave a gold streak, while other minerals like pyrite and mica leave black and white streaks, respectively.

Gold grade measures the amount of gold within ore before it's processed, while gold purity refers to the percentage of gold in the final, refined product. Gold purity is either measured in fineness (the number of parts gold per 1,000 parts) or gold karats, where 24 karat gold is deemed pure.

These color changes can be an indicator of gold because gold often occurs in altered rocks or along rock contacts. 17) Iron Staining & Gossans. Not all veins produce much quartz. Gold-bearing veins can consist of calcite or mostly sulfides—which often weather into iron-stained spots when the pyrites convert to iron oxides.
