Name and surname:
Andradite garnet in chlorite matrix from contact metamorphic rocks from Kope mountain in Pohorje, Slovenia. The crystals have a characteristic rhombododecahedral shape (right) and are embedded in the rock, leaving negative imprints when separated (left). The largest andradite crystals from these localities measure up to 9 cm in diameter, the one on illustration is 3,5 cm wide. The Kope skarn deposit is rich in magnetite veins that were mined as a high quality iron ore in the late 18th century by Baron Zois.
