Indeed, gold is about eight times heavier than the quartz rock. This characteristic is essential to understand how free gold behaves in nature. Due to its weight, it is likely to sink rapidly when in water, and fall even further when placed in dry materials such as sand and other types of placers. Erosion and Transportation
