Gorgeous antique moonstone ring with lovely detailed shoulders and rounded greyish moonstone cabochon.
The flat, gold band has no purity mark but tests for approx at least 10k+ yellow gold. There is a maker's mark of an N within a diamond shape.
Ring is currently sized to a 6.5 but sizable by a professional jeweler. Total weight is approx 1.8g.
Moonstone is a wonderful antique greyish tone with some muted blue reflections in the light. There is surface wear to the stone that might benefit from a light polish if one desired.
