♊︎ The lucky stone of Gemini: agate
Colour: yellow and banded. Also named: citrine, tiger's eye.
Agate grew in layers, band upon band, as many-sided as Gemini. Tradition says it calms a quick mind and helps you stay with one thing.
The lucky star of Gemini in the real sky: Pollux.
The assignment of stones is tradition, and the lists differ. It is not medicine.
