Cava Val di Merse (Cava Italcave), Monteriggioni, Provincia di Siena, Toscana, Italia
Group of 3 rubble quarries (only this one active) approx. 3 km SE of Monteriggioni, along the National Route 2 "Cassia" in the sourronding of Km. 238 in the Grotti breccia (local formation, Miocene, continental facies).
The black quartz crystals (always doubly terminated) have been found also outside of the quarries; sometimes the matrix is poor of cement and clayey and so it is possible to find free cristals too.
