This Quartz specimen, accompanied with a white Richard W. Barstow collection label, is a classic example of the Eisenkiesel variety. The hexagonal pyramidal crystals of Quartz to 2cm completely cover the red Hematite matrix. The colour is from water clear colourless to very slightly smoky. The Eisenkiesel are the transparent Quartz crystals with orange Hematite inclusions, which sit like orange jewels in the centre of the specimen.
