Magnetite is one of the main iron ores, and is a member of the Spinel group. It is the most magnetic of all the naturally occurring minerals on Earth, and is known as a ferromagnetic. This means it is attracted to a magnet, but can also be magnetized to become a permanent magnet itself. Magnetite can be found naturally magnetized, these pieces go by the name Lodestone. Lodestone specimens rarely have a strong magnetic pull, so may not pick up large metal objects, or stick to a fridge etc, but they do attract small iron filings and such, and this was how ancient people first noticed the property of magnetism.

Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device. Once this specimen is sold, we will update this listing with new similar selected item, with a new photo and dimensions so this listing will change after you purchase.
