Difference Between Magnetite And Hematite In Hand Specimen

Hematine on the other hand, also know as Magnetic Hematite, is a completely man made stone. Hematine (Ba,SrFe12O19) bares no resemblance in chemical make up to that of Hematite or Magnetite though it is often claimed to be made from natural Hematite.

We sell over fifty varieties of tumbled stones and hematite is one of the most popular. People enjoy its mirror bright luster and its silver color. But, most of all, they are delighted by how its high density produces a hefty sensation when it is handled. There are a number of products being sold with the name hematite, such as magnetic hematite and iridescent hematite.

However, the streak of most minerals is similar in color to that of the mineral in hand-sample (see the example of galena pictured below). Magnetism: This one is pretty self-explanatory. If your magnet adheres to your mineral, you definitely have some form of iron mineral, quite possibly magnetite or hematite (see photos below).

Difference Between Magnetite and Hematite . Jan 31, 2018Magnetite is an iron ore where iron can be found in the form of Fe 3 O 4. Magnetite is ferromagnetic, which means, magnetite particles are attracted to an external magnetic field ; magnetite particles can act like tiny magnets when magnetized.

Hematite crystallizes in the trigonal system, forming with the same crystal structure as corundum (sapphire and ruby). It is harder than pure iron, with a hardness ranging from 5.50 to 6.50 on the Mohs scale, which is similar to opal or turquoise. Hematite is often confused with 'hematine', a magnetic imitation form of hematite.

The advantage of using “Magnetic Hematite” in jewelry is that the magnetic properties of this composite material is consistent, does not vary and will not lose its magnetic properties. The composite material which forms “Magnetic Hematite” is much easier to produce in detailed shapes and looks and feels like the non-composite material.
