Abstract: A method of diamond synthesis, by which a reaction mixture is prepared comprising, taken in direct contact, a carbon-containing material and a combination of components selected from the group containing silver chloride, calcium carbonate, calcium oxide and from a group containing aluminium and boron. Then the reaction mixture is subjected to the action of a temperature of at least about 1800.degree. C and a pressure corresponding to a selected temperature within the diamond stable region during the time required for forming a diamond.
