Many gold nuggets formed as clusters of gold crystals from very hot water in cracks and fissures in hard-rocks, often with quartz.

Gold-Bearing Quartz is one of the world's rarest forms of natural gold. It is found underground by hard rock miners in only a few locations in the world. This unique formation is being mined 1,500 to 2,500 feet below the earth's surface. The natural veins of gold were formed by hydrothermal pressure deep within the earth millions of years ago.

If you can find a sufficiently large piece of the 'gold' in your rock (it can be the same one you used your fingernail on), take a steel razor blade or very sharp knife and attempt to cut into it. If the blade slices through then you have found gold! If not, it's more likely that you're looking at pyrite or some other mineral.

In many cases, quartz can be found at any distance from the pluton, and often the distant ends of the veins are void of ores and simply filled with quartz.

Why is gold found in quartz? Gold is formed naturally in quartz deposits in the earth. When erosion takes place, exposed veins of gold break off and wash into rivers and streams. The natural movement of the water tumbles the gold against sand and rocks, forming the Natural Gold Nugget. This gives each nugget its texture, shape, and character.

Three things I need to mention: 1) Not all white quartz will contain gold lines. 2) Gold is also found in non-rusty quartz. 3) Some thicker (cruder) gold lines will be iron pyrite.
