Valuable vs. Invaluable

Valuable means something has a high monetary worth or great utility. It can be measured, priced, or replaced. For example, a diamond ring, a luxury car, or useful market data are valuable.

Invaluable means something is priceless. Its worth is so immense that it cannot be measured in terms of money, and it cannot be replaced if lost. For example, a mother's advice, a lifelong friendship, or life-saving assistance in a crisis are invaluable.
