Also called: Leukonychia · White flecks · Black spots

Where on the hand: On the nail plate of any finger or the thumb. Which finger the spot appears on decides the reading.

What it looks like: Small opaque white flecks, or discrete dark marks, within the nail plate.

The most-asked-about mark on the hand. Western reading treats white spots as a vulnerable nervous system, calcium or mineral depletion, stress, or simply minor trauma to the nail matrix. The Indian divinatory rule is flatly binary: **white spots are auspicious, black spots inauspicious** — and the finger decides in what department.

Western reading: Western sources read the same white flecks as trauma or mineral depletion and attach no fortune to them at all.

Read with care: The black spot on the Mercury nail is quoted in the sources as "possibility of death in the coming time". This is folk belief, recorded here for completeness only; it is not a prediction and must never be told to anyone as a finding. White flecks in nails are almost always minor knocks to the nail matrix.
