⛰️ THE NATURAL FACTORY OF CALCAREOUS ONYX ✨
Have you ever wondered how this impressive stone is formed? Hit play on the video and join us at one of the most interesting locations in the Tehuacán-Zapotitlán area to discover its true origin.
It all starts with a work of natural engineering: rainwater filters through limestone, dissolving minerals along the way. Upon finding underground fractures, calcium carbonate slowly precipitates, sealing the spaces layer by layer to form the famous calcareous onyx. This patient process creates unique characteristics:
▪️ Hidden geodes: In some fractures, hollows remain where the mineral grows freely, revealing perfect crystals inside.
▪️ Unrepeatable color bands: Small amounts of other chemical elements mix during formation, creating spectacular transitions of white, gray, yellow, orange, and green colors. No two pieces are alike!
