The blue-green iridescence of Greek fir honey is an optical property of the honey itself.
The effect is consistently observed and is generally attributed to the honey's particular mix of sugars and colloidal particles scattering light. The precise mechanism has not been settled in published work to the standard this catalogue reserves for established evidence, so it is recorded here as emerging rather than settled — the observation is not in doubt, the explanation is.
What this does not claim: This does not claim the iridescence indicates quality, purity or any health property, and it does not claim the mechanism is settled. The observation is reliable; the explanation is not yet.
