Sant'Olga Tunnel, Monte Arsiccio Mine, Sant'Anna di Stazzema, Lucca Province, Tuscany, Italy
Single Crystal
Size Range: 
Micromount (under 1cm)
0.01 × 0.03 × 0.02 cm

One of the rarest and weirdest minerals known, the barium titanium vanadium arsenite bianchiniite (IMA 2019-022) comes from a one-time find at the prolific Sant'olga (low) tunnel of the Arsiccio mining complex. Its formation derives from unique geochemical conditions of the vein, while close by the same overall chemistry results in derbylite-group minerals. These peculiar conditions don't imply low stability of the mineral itself, which can be kept indefinitely at normal conditions. Bianchiniite is translucent, dark reddish brown, and crystals have a marked tabular habit.

The only existing matrix specimen is the holotype, while at the latest Munich show a handful of crystal fragments, individually tested and mounted on a capillary for single-crystal XRD, were made available to collectors. The specimen offered here is a unique opportunity of acquiring an extremely rare natural phase.
