Abstract
With a homogenization experiment (700°C, 2 kbar) on melt inclusions in polished thick sections of emeralds from the Habachtal, it could be demonstrated that the primary crystallization of emerald started at significantly higher temperatures than previously assumed. This experiment confirms the prediction in the precursor publication on this subject. Supercritical conditions around 700°C and 5 kbar fix the start point for the emerald crystallization.
