The article presents a study conducted by the Gemological Institute of America (GIA) and the Max Planck Institute for Chemistry (MPIC) on the trace-element characteristics of two nacreous pearl samples. The results revealed that the pearls comprised layer-like zones having distinct trace-element signatures related to both freshwater and saltwater environments, as confirmed by spot analysis conducted by laser ablation inductively coupled plasma mass spectrometry.
