Oleksandr Diachenko’s sculptures are kept in Khmelnytskyi, Zaporizhzhia, Cherkasy Regional Art Museums, Lviv National Art Gallery named after Borys Voznytskyi and private collections in the Netherlands, Germany and Croatia. The sculptor’s solo exhibitions were held in the leading galleries of the capital.
Oleksandr Dyachenko’s works are a force of calm and self-absorption, a monumental purity and an essence devoid of all superfluous. The sculptor deliberately concentrates the energy of the object in one point to enhance its effect. Simple shapes and laconic lines tend to be universal, the understanding of which does not require any further explanation, only the openness of the viewer.
Currently, the artist’s works of several series are exhibited at Art Ukraine Gallery.
