Formula:

(Na2,Ca,K2)5Al10Si38O96 · 25H2O

Colour:

Colorless, red-orange

Crystal System:

Monoclinic

Name:

Originally referred to as sodium-rich dachiardite. Renamed to the current form in 1997 (Coombs, et al), as the Na-dominant member of the dachiardite series. The root name is in honor of Antonio D'Achiardi (1839–1902), Professor of Mineralogy, Universitá di Pisa, Italy, who first described dachiardite-(Ca).
