ELI5: Why words like "invaluable" and "valuable" and synonyms but not "destructible" and "indestructible"?

Edit: I just realized there is "and" instead of "are" before the word synonyms.

invaluable means "cannot be valued" meaning just like indestructible means "cannot be destroyed." Colloquially, when we say something can't be valued we mean the thing is so important that you literally can't conceive of a finite value you could assign to it.
