♋︎ The lucky stone of Cancer: moonstone
Colour: silvery white. Also named: pearl, chalcedony.
Moonstone shimmers like moonlight on water, and the Moon is the planet of Cancer. Tradition links it with feeling, a sense of shelter and a calm night's sleep.
The lucky star of Cancer in the real sky: Tarf.
The assignment of stones is tradition, and the lists differ. It is not medicine.
