What it actually is
Moonstone is (Na,K)AlSi₃O₈ before it is a story. The lattice is monoclinic, Mohs 6–6.5, and the eye meets white.
The better pieces still come out of the ground in Sri Lanka, India, Madagascar. June’s feldspar floats a blue sheen that moves when the cabochon turns, adularescence from thin layers.
What the old tradition whispers
The parlour tradition ties Moonstone to water and to the sacral centre. The old site stood it near: Cancer, Libra, Scorpio. Old tables sit it beside June.
How not to turn it to ash
A hard stone survives a daily ring, yet two diamonds in one box will scratch each other. Warm water and a soft cloth are enough.
