when do we say gold or golden?
golden rule, golden Globe
gold watch, gold card.
Naturally if something is already called the "Golden Rule" or "Golden Globe" you don't change it.
A gold ring/necklace/coin/medal.
If something isn't made of gold, or a specifically gold colour, often golden is better - 'golden brown toast', 'The Golden Girls': but then 'The Gold Coast'.
