Crystals for Protection
The stones traditionally chosen for protection, what each one is used for, and how to look after it.
Protection is the most-asked-for property in crystal practice, and the answer has been consistent for a very long time: dark, dense, iron-bearing stones, placed at the threshold rather than carried on the body. Black tourmaline by the door, obsidian on a desk, hematite in a pocket. Traditionally these stones are described as absorbing rather than deflecting, which is why the same tradition insists on cleansing them regularly.

How to actually use them
Tradition is more specific about method than most articles let on. Grounding and protection stones are held or placed rather than worn. Sleep stones go on the nightstand, not under the pillow where they get lost. Throat stones are worn at the neck. Money stones go where the money is handled. Pick one rather than a handful: the consistent instruction across the literature is that a single stone with a stated intention beats a pocketful without one.
If you would rather describe the feeling than pick from a list, the crystal finder starts from what you need and works backwards to the stone.

Fact and tradition, kept apart
The mineral family, the Mohs hardness and the water verdict on each card are checkable physical fact, drawn from standard mineralogical and gemmological references. The chakra, element and purpose associations are tradition, published across the modern crystal-healing literature and offered here for reflection rather than as fact.
