A nugget of gold is a naturally occurring piece of gold that has not been refined or processed. These nuggets can vary in size, shape, and purity, often found in riverbeds or as part of mineral deposits. Gold nuggets are typically formed through geological processes that concentrate gold particles over time. Gold nuggets are highly valued for their rarity and beauty. They are often sought after by prospectors and collectors, and can be used in jewelry or as investment pieces. The discovery of large gold nuggets has historically led to gold rushes, attracting many people to areas rich in gold deposits.
