Where the colour comes from
Quartz is clear on its own. A little iron in the crystal, changed by the natural radiation of the surrounding rock, turns it lilac to deep violet. Heat undoes it: warmed amethyst turns yellow, which is how much of the citrine on the market is made.
What tradition says
The ancient Greeks linked it with staying sober, and medieval bishops wore it in their rings. It was once among the most costly stones, until large finds in Brazil made it a stone for everyone. In crystal practice it is linked with the crown chakra, with calm and with clear thinking.
How people use it
Most keep it where the day ends: on a bedside table, by a reading chair, beside a meditation cushion. Think of it as a cue, a small and beautiful object that marks the moment you choose to slow down.
Care
Keep it out of strong sun for long spells, as the colour can fade. Rinse in plain water and dry with a soft cloth; avoid heat.
