Apatite, Iron Monarch Quarry, Iron Knob, SA
Size- 3.5cm x 2.5 cm
Well formed hexagonal clear crystals of apatite lining a cavity, on a sparkly hematite background.
These clear crystals are most probably fluorapatite. Great under a microscope, a lot of Iron Monarch minerals were better viewed under magnification, but sometimes there was enough coverage to make a cabinet speciman. Mine closed in 1997 so specimans of these are hard to come by.
