A stone carries within it the way it was formed and structured. My knowledge of its birth process, of its crystallization process, of its composition, gives me different perspectives that guide me when approaching a stone. The cubic structure of a fluorite, the composition of copper-bearing stones, the metamorphic formation of lapis lazuli, the quadratic crystallisation of zircon… are all different structural aspects which share correspondences with different human natures, reveal to me a stone’s calling and with which each person can associate his or her own reality.
