Pure gold does not fear the smelter

An inch of time is an inch of gold, but you can’t buy that inch of time with an inch of gold

Rare commodities are worth more than gold

Peace and tranquility are a thousand gold pieces

Gold is tested by fire, man by gold

Gold has its price; learning is beyond price

Gold and silver are mingled with dirt, till avarice parted them

A book holds a house of gold

Yellow gold is plentiful compared to white-haired friends
