Precious, valuable, invaluable, and priceless mean extremely valuable. Precious means emotionally important, not measured in money. Valuable means worth money or useful. Invaluable means so useful it cannot be priced. Priceless means rare enough that no price fits, like art; not compared: its 'funny' sense.

这四个词都形容某样东西价值很高，但价值的来源和典型搭配不同：precious 偏重情感、valuable 偏重可衡量的价值、invaluable 偏重实用性、priceless 偏重实物的极端珍贵。这里不比较 priceless 的另一个口语义项——形容表情或场面“滑稽好笑”。
