Abstract
The effect of high temperature on sulfide inclusions in diamonds was studied. The object of study was sulfide-bearing diamond crystals from Yakutian kimberlite pipes. The experiments were carried out on a multiple anvil apparatus BARS with a solid-phase refractory oxide cell at 5.0 GPa and 1000-1600
