Obelisk — Tourmaline · 5 cm

An obelisk with even faces, polished along every edge — a form inherited from Egyptian architecture, where it marked the passage of the sun.

Prismatic crystals striated lengthwise, whose color varies with the elements they captured.

What tradition says. Tradition makes it a stone of protection and of sorting out.

Use & care. It sits as well on a bookshelf as on a ritual tray; its verticality alone creates a visual anchor. Dust with a dry cloth. Sharp edges mark if knocked.

• Tourmaline shows the widest range of colors of any mineral.
• Indicative size: 5 cm
• 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.
