Hematite is an iron oxide mineral with a hardness of 5-6. It can be found in several different forms, both as crystals and masses, which may be silvery or reddish-brown or black. Crystals forming as hematite roses are very attractive, but to find true rhombohedral crystals is much harder. Hematite also forms in "kidney growth", being either glassy or earthy red. The most common way we will find this stone is in its tumbled form, where it is easy to identify because of its silvery reflective colour, and the fact that it feels heavy for its size.
Hematite is cold to the touch at first, but will warm up surprisingly fast. Often it feels as if it is stuck to your palm - in this case you may be benefiting from its strong grounding qualities. Hematite has great strength and is an excellent foundation stone. It is also a bit of an enigma as, despite its strongly grounding energies, it can feel distinctly "off-planet". But not much can beat it for its grounding effects if you place one at the feet or on the navel, or hold two in each hand. Hematite is also an excellent grounder and balancer of the energy centres and can also have the effect of immediately closing down any chakra if placed on it - this can be useful on the higher chakras cases of psychic overload. Hematite is good to try if you have a "3rd eye headache": simply gently massage the area with one stone. Along with its grounding effects, hematite is also very reflective and so is useful for reflecting or deflecting anything you do not want in your energy field. For this reason it can be useful to wear or carry as a protective stone. Physically hematite has always been regarded as useful to work on blood and circulatory disorders and the kidneys.
