In this paper we have considered an interacting Ricci dark energy in flat Friedman-Robertson-Walker (FRW) universe. We have reconstructed the Hubble parameter under this interaction. Also, we have investigated the statefinder diagnostics. It has been revealed that the equation-of-state parameter behaves like quintessence in this interaction and from the statefinder diagnostics it has been concluded that the interacting Ricci dark energy interpolates between dust and ΛCDM stages of the universe.
