Il diaspro (parola che è di origine persiana, ma connessa anche con il greco-latino iaspis, "pietra screziata") è una roccia sedimentaria mono-mineralogica, ossia formata da un unico minerale, composta da quarzo (SiO2), e contenente sovente alcune impurità, solitamente composti di ferro che conferiscono alla roccia vivaci colorazioni, rendendola ricercata come pietra semi-preziosa per la lavorazione in opifici.
