Why light, clear stones feel familiar
You've stood in a crystal shop and your hand went straight to the light ones. The clear ones. The ones with layers or bands or something interesting happening inside. Agate. Quartz. Something pale blue. You didn't read the label — you picked up six and put back four. And later, when you looked it up, the internet told you those stones are "good for Gemini" — but nobody explained why.
Why most crystal lists feel random
Every crystal site gives a different list. One says Citrine. Another says Amethyst. A third says Malachite. They can't all be right — and the reason they disagree is that they're guessing. There's no framework connecting the sign to the stone.
Without a framework, a crystal list is just vibes with better formatting.
