Nontronite
Nontronite
The soft yellow-green clay named for a small town in the Dordogne.
Nontronite is an iron-rich smectite clay, soft, yellow-green, and named for Nontron in southwestern France where it was first described in 1827. Color comes from ferric iron held within its phyllosilicate sheet structure. Hardness is just 1.5 to 2 on the Mohs scale, which makes it a display piece rather than a daily-carry stone. Our specimens are individually photographed pieces from Minas Gerais, Brazil, sold as discrete pieces with their own locality and condition notes. Traditionally associated with grounding, restorative calm, and emotional balance, and most often connected with the Heart and Root chakras together.
