Gold nugget on my finger

This is gold nugget on my finger.

Gold nuggets in nature are all different shapes, depending upon their origin. They can be from eluvial or placer sources, and the distance they have traveled to reach us as humans today.

Eluvial gold is found near a motherlode vein of quartz which has been eroded by natural processes such as weathering over time. This erosion causes the pieces of gold (nuggets) to take various angles based on how close they were to their source point when extracted from the earth, and where they were transported through rivers or streams.

On the other hand, if a piece is found in an alluvial deposit, we would find them more oval-shaped. This is due to their long journey over time, as sediment carried by water currents before reaching our hands today. This means it has been moved further away from its original source location, giving us this unique shape of gold nuggets.
