This is thought to be one of the largest hail stones ever recorded. It fell in the backyard of Maria Natividad Garay, who lives in the foothills of Villa Carlos Paz, Argentina, on the 8th of February 2018. It is roughly the size of a grapefruit and fell in a fifteen-minute downpour that smashed her skylights and left her home filled with ice that piled up like snowdrifts on her floor. She still keeps today in a zip-locked bag in her freezer.
