ethereal beauty

Ethereal beauty describes a delicate, otherworldly loveliness that seems too refined for the physical world—the kind that appears almost translucent or spiritual rather than solid and earthly.

The phrase evokes images of pale light, fine features, and an impression of fragility: She had an ethereal beauty, as if she might dissolve into mist.

Often applied to art, music, or natural phenomena that inspire a sense of the sublime.
