Mineral: Magnetite
Locality: Avissalos Bay, Serifos Island, Cyclade Islands, Kykládes Prefecture, Aegean Islands Department (Aiyaíon), Greece
Dimensions: 45 mm

Description: XRD analyzed in the University of Natural Resources and Life Sciences, Vienna. No Hematite left - this is pure Magnetite!!!! I have got this information from Peter Schlögl, a highly respected collector, dealer and personal friend. It seems all "Hematites" with Prasem Quartz are Magnetite. No Hematite was found during analysis.
