Purple Crystals
Every purple stone in the database, with what it is made of and what it is traditionally used for.
Purple is the colour people associate with the crown and the third eye, which is why almost every purple stone on the shelf is sold for sleep, intuition or a quieter mind. In minerals the colour usually comes from iron or manganese sitting in the crystal lattice, and that is also its weakness: the colour centres that make amethyst purple are light-sensitive, so most purple stones fade in a sunny window. Charge them under the moon and keep them out of direct sun.

Fluorite
Fluorite · Mohs 4
Banded purple, green and blue. The desk stone, associated with order and clear thinking.

Iolite
Cordierite
Violet-blue and dramatically different from each angle, which is how Norse sailors are said to have used it.
Worth knowing: Iolite is strongly pleochroic: it shows blue, violet and near-colourless depending on the viewing angle. That is a real optical property, not a trick of the setting.
Kunzite
Spodumene
Pale pink spodumene with a strong lengthwise sheen, tied to opening a guarded heart.
Worth knowing: Kunzite fades in sunlight and cleaves easily along one plane, so a knock in the wrong direction can split it.
Lepidolite
Mica · Mohs 2.5–3
Lilac mica that genuinely contains lithium, and traditionally the anxiety stone.

Sugilite
Cyclosilicate
Deep magenta-purple, only identified in 1944, and traditionally given to people who absorb the mood of a room.

Why the colour matters
Colour is the fastest way into the correspondence system, because the chakra scheme is itself colour-coded, and most traditional associations follow the colour rather than the mineralogy. It is also the least reliable guide to how a stone must be treated: two stones of the same colour can be a hard silicate and a soft copper carbonate, and only one of them survives a rinse. Each card above carries its own verdict, and the safety checker has the full reasoning.

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.
