Uvarovite from
Dossi di Franscia (Franscia Mine; Franscia Mines; Franscia Quarries), Campo Franscia (Franscia), Lanzada, Lanterna Valley, Malenco Valley, Valtellina, Sondrio Province, Lombardy, Italy

Classification
Species:Uvarovite
Formula:Ca3Cr2(SiO4)3
Comments:Emerald-green garnet crystals in chromitite fissures, traditionally considered “uvarovite” (Sigismund, 1948; Gramaccioli, 1962; De Michele, 1972, and other authors), are actually Cr-bearing andradite with a content in Cr2O3 varying inside the crystals from 9.6% in the core to 0.8% at the rim (Bedognè et al., 1993; Sciesa, 1993).
Confirmation
Validity:Erroneously Reported
