Gold or golden nugget?
I can't figure it out. I've seen both been used, but a nugget is presumably gold, or can golden be used as well?
Solution 1:
Both meanings overlap, but not perfectly.
"Golden nugget" is ambiguous. It isn't clear if you mean that the nugget is made of gold, or if the nugget is golden in color.
"Gold nugget" indicates that the nugget is made of gold.
