Geological facts

Natural gold nuggets are rare; less than 2% of the world's gold is found in nugget form. The 'Welcome Stranger' is the largest alluvial gold nugget ever found.

Field identification & locations

Identify by its high density (feels very heavy for its size), malleability (will dent, not shatter), and brilliant metallic luster that does not tarnish. Found in auriferous regions using gold pans or metal detectors.
