have a heart of gold
Meaning
To be very kind, generous, and caring by nature.
Origin
The “heart” symbolizes one’s character or feelings, and “gold” symbolizes great value and purity. The phrase has been used in English since at least the 19th century to praise someone’s kindness.
Notes
A warm compliment meaning someone is genuinely kind. Often used to contrast tough appearance with kindness. Casual and common; can sound a bit gushy if overused.
