A guide to the minerals in the Zendiac collection. Each card carries a stone on one face and, on the reverse, the naturalist, scholar or collector across history who first set down what it means. Turn a card to meet them.

This is every stone Zendiac offers, gathered as a single archive. Each card shows a mineral on its face.
Every card hides a second side. Tap the turning mark above a card to flip it and meet the historian who first recorded that stone — its grounded, checkable meaning across time.
