Most of these diamonds belong to eclogite paragenesis. Mainly nonkimberlitic rocks are primary sources of mantle garnets from sedimantary rocks. Paragenetic associations of garnets from kimberlites of Eastern Pryazovya block show evidence about formation of kimberlitic magma near boundary of diamond- and grafite abyssal facies. The areas in Ukraine, occupied Volyn' block, should be referred to the most perspective region of diamondiferous kimberlite deposits. Kirovograd kimberlites and Western Pryazovya lamproites belong to nondiamond-bearing rocks.
