Description
A dense, rounded natural gold nugget exhibiting significant water-worn characteristics. The piece features a deep yellow base color typical of high-purity native gold, partially obscured by a dark, earthy patina and iron-stained oxidation. Its bean-like shape suggests it was moved by water in a stream or river bed (alluvial gold) over a long period, smoothing its once-jagged crystalline edges into a satisfying, tactile form.

Interesting Facts
The 'purity' of nuggets usually increases with distance from the source as silver is leached out.
