Il piropo è un minerale appartenente al gruppo del granato. Fa parte della serie dei granati con l'almandino e la spessartina (conosciuta anche con l'acronimo "piralspite") della quale costituisce l'estremo contenente magnesio; l'almandino è l'estremo che contiene ferro, mentre la spessartina è l'estremo che contiene manganese.
