Morphology

adamantine = adamant (transparent) = adamant + ine

Formed from 'adamant' (a very hard substance/diamond) + '-ine' meaning 'of or like', so the meaning 'like a diamond/unbreakable' is directly derived.

Etymology

Adamantine comes from an old Greek word adamas meaning 'unbreakable' and shares the same root as diamond. So if something is adamantine it is extremely hard or unbreakable, like a diamond.
