We studied a collection of microdiamonds from the Zeleny Yar Neogene placer on the Ros’-Tikych megablock of the Ukrainian Shield, which consists of 102 microdiamonds, with crystal sizes 0.2-0.5 mm, using crystal morphology, photoluminescence, infrared and Raman spectroscopy, isotopic composition of carbon and helium of microdiamonds. Crystal forms are dominantly octahedra, others are cubes, combinational crystals {111}+{110}+{100}, cube-octahedra, and transitional forms {111}+{110}; rhombic dode
