The spondylus shell, from the waters off of the coast of northern Peru and Ecuador, has been important to Andean peoples since pre-Columbian times (indeed perhaps as early as the third millennium BCE), serving, among other functions, as an offering to the gods (especially to Pachamama, the earth goddess) and as a material of value incorporated into jewelry and other high-status personal adornment.
