Ghasemi was honored at the Khane-ye-Koshti (Wrestling House) in Tehran and members of Iran freestyle national team were in attendance.
Uzbek freestyle wrestler Artur Taymazov was stripped of his London 2012 Olympic gold medal last week after re-analysis of stored samples.
Ghasemi has become the new gold medalist, Bilyal Makhov from Russia remains silver, and Tervel Dlagnev from USA is the newest bronze medalist.
