Abstract - Summary 
(short description):
In panned samples of the alluvial and glacial deposits of the perspective area \"Ustya\" is found
9 crystals of diamond of various morphology (including octahedral crystals). They have the size from 0,5 up to 3,8 mm and weight up to 52 mg. Crystals are characterized by sharply lowered nitrogen concentration in “B” form and very low concentration platelets and hydrogen. On a complex of morphological attributes and a ratio of structural impurity diamonds of area \"Ustya\" differ from diamonds of known kimberlitic and placers deposits of Arkhangelsk, Ural and Timan. It can specify receipt of crystals from new, unknown diamondiferous mesozoic kimberlites.
