Authigenic Black Quartz

Monteriggioni, Siena Province, Tuscany, Italy

Black quartz from Monteriggioni, Tuscany, is a rare authigenic variety formed within the deep evaporite layers of the Burano system rather than in igneous rock. Unlike conventional smoky quartz, its deep black color comes from bituminous and graphite-rich inclusions, giving the crystals a strikingly dense appearance and stable coloration.

Its rare pseudo-bipyramidal form, complete terminations, and naturally etched surfaces create an exceptional geometric beauty. Formed around 20 million years ago in high-salinity fluids, the crystals enclosed surrounding bituminous material before becoming preserved in a yellow-brown breccia matrix, creating the dramatic contrast seen today.

※ Includes a minID Mineral Identity Certificate, developed through collaboration between Mindat.org and the Taiwan Central Gem Laboratory (TCGL), featuring bilingual records and a QR code linking to its permanent Mindat.org page. ※
