Semicircle / Half-Moon

अर्धवृत्त · ardhvritt / अर्धचंद्र · ardhachandra

Also called: Half-circle · Half-moon · Arc · Moon sign

Where on the hand: The one placement the sources name is the Mount of the Moon; the separate “half-moon” sign is not given a fixed position.

What it looks like: A single arc — half a circle — with its ends open, typically 4–10 mm across.

Very thinly attested. Palmistry-Astrology gives essentially one line: “Semi-circle sign on the Mount of Moon indicates that the bearer is distressing.” A separate half-moon sign is treated by some popular Indian sources as a distinct auspicious or leadership mark.

On each mount

**Moon / Luna** — “the bearer is distressing” — the only placement given in the sources.
**Other mounts** — no readings recorded; do not extrapolate.
**Compare the circle** — a closed ring on the Moon is read as death by drowning (Saint-Germain) or blindness (Palmistry-Astrology); the open arc gets only the vague distress reading.

On each line

**Not a line mark** — the semicircle is not given any line reading in the sources.
**Distinguish from a bow** — a bow (dhanush) is an arc with a straight chord across it and is read positively; an open arc alone is not.
**Distinguish from a broken circle** — Dale's broken circles are “less powerful than concentric circles” but still belong to the circle family, not here.

Where it is positive

**The separate half-moon sign** — Funchannel lists a “Moon sign” indicating the person is “destined to rise to a high-ranking position.”
**Popular Indian usage** — some sources treat the half-moon as an auspicious leadership mark, in direct tension with the Palmistry-Astrology distress reading.
**Low confidence** — the sources themselves are thin here; both readings should be treated as poorly standardised.

Read with care: Both the negative and the positive readings of this shape rest on a single line each. Treat the semicircle as low-confidence and poorly standardised; the tradition has not settled what it means or even whether it is auspicious.
