In this work it was used the system of four die displacement sensors for anvils clearance measurement with the aim to keep watch on pressure variation in "anvil with hollow" type of high pressure apparatus during diamond synthesis. It was shown that natural direct connection between pressure inside reactive cell and height of deformed gasket exists independently of the cause of pressure change. The special inserts and previously sintered metal-catalyst were used to stabilize the process of diamond single crystals synthesis. Their application allowed to reduce pressure fall in a reactionary cell from 0. 13Gpa/min to 0. 02GPa/min, and also to raise yield of high quality diamond crystals.
