A 6.6g sample of Magnesium metal in the form of a beautiful distilled crystal cluster. This is high purity 99.99%. These are not the boring Mg samples you see listed like turning, pellets, or ingots.  Distilled crystals like these are hard to find, they're usually melted down during the purification process and cast into large ingots of Magnesium metal.  There are some oxidized spots at the base and bottom of the crystals but the piece displays well.
