Magic pendulum — Sunstone

A warm orange run through with coppery flashes that light up under direct light.

A pendulum cut from natural stone and hung on its fine chain; the balance is checked piece by piece, without which the swing drifts.

In tradition. Tradition links it to impetus, to joy and to presence in the world — the solar counterpart of moonstone.

In practice. Held with the chain free between thumb and forefinger, elbow resting. You first agree your movement conventions, then you ask. Hang it up rather than leaving it loose, so the chain does not tangle.

• Its flashes come from hematite or copper inclusions oriented in the same plane.
• A natural piece: shade, veining and dimensions vary from one example to the next

A decorative object for personal practice. It is no substitute for medical advice or treatment.
