After decades of speculation without material proof, the yellow-orange luminescence of scapolite is definitely assigned to (S 2 ) - activators trapped in [Na 4 ] square cages. Synthetic sulfur-doped scapolites confirm the implication of sulfur species in luminescence. Formally, the emission and excitation spectra of various polysulfide species were calculated. The excellent match between theory and experiments for (S 2 ) - dimers provides definitive proof that it is the cause of the yellow-orange luminescence in scapolite.
