Hematite While the forms of hematite vary, they all have a rust-red streak. Hematite is harder than pure iron, but much more brittle. Huge deposits of hematite are found in banded iron formations. Grey hematite is typically found in places where there has been standing water or mineral hot springs, such as those in Yellowstone. The mineral can precipitate out of water and collect in layers at the bottom of a lake, spring, or other standing water. But hematite can also occur without water, as the result of volcanic activity. Color Hematite is a mineral appearing as metallic gray, red gray, red brown with a metallic luster; it may even look more like a metal than a mineral when encountered in nature. The name Hematite originates from the Greek word for blood, haima, which refers to the dark red color of the mineral’s streak. When crushed, Hematite will turn water red. Specular Hematite (Hematite with a reflective finish) has iridescent colors in its finish. Thin slices of Hematite appear red and transparent. Crystal Hematite crystals are members of the Trigonal System group, which is a subset of the Hexagonal system. It is also conchoidal and may appear as a phantom within other crystals. Uses Hematite, with its high iron content is a very useful mineral. As just mentioned, its chemical composition contains a high percentage of Iron (70%) and it is the primary ore used to create Iron. Beyond its use as an ore, jewelers appreciate its shiny luster for creating engravings, cameos, cabochons, beads and imitation diamonds. Red Ochre is a pigment created from Hematite that was used in Native American cultures for face paint. Forms Hematite appears in many forms in nature, such as Kidney Ore, a bumpy ore that has an appearance likened to a kidney; Hematite Rose, a formation with crystals in the shape of petals; Tiger Iron, a sedimentary rock with Hematite mixed into its multiple layers; Oolitic, sedimentary deposits of small, circular Hematite grains; and Micaceous Hematite, a scaly, shiny stone valued for decorative uses. Its soft Earthy, form is called Red Ochre. Hematite often appears within other crystals such as Aventurine or as phantom crystals. Hematite on Mars Hematite has even been detected on Mars. In 1998 the Mars Global Surveyor (MGS) spacecraft found a large deposit of hematite near the equator of Mars. "We believe that the gray hematite is very strong evidence that water was once present in that area," said Victoria Hamilton, a planetary geologist at Arizona State University (ASU). She went on to say, "we think the deposit is fairly old. It was buried, perhaps, for several hundred million years or more and now it's being exposed by wind erosion. Water is essential to life as we know it and this finding bolsters the theory that life may have existed on Mars". |

| Item # HM17007 Specular Hematite Crystal from South Africa $8.00 |
| Anyone can produce the wildly unique hypnotic sound simply by tossing them a few inches into the air. With a little practice, higher tosses will result in even more impressive "singing". The fun is contagious! The magnets are quite powerful and make handsome fridge magnets, that is, if they ever get a rest from their playful owners. The singing is like some kind of strange sound from another world. Sometimes they make a soft whistle or a loud zip sound. Watch them dance a magnetic ballet of attraction and repulsion; clashing, spinning and making an insect chirping sound in the process. ( approximately 2-1/2 inches long each) How To Do It; Hold Singing Magnets in the palm of one hand using your thumb, separate them to about a half inch apart. After a little bit of practice, when you toss them upward they will produce a wild sound. Grab the pair of Singing Magnets with your thumb and first two fingers and squeeze (pinch) them out of your grip. When they are 'Launched' in to the air they will whistle. Try spinning them across the desk! Warning, this can be really loud! Watch out for hard surfaces (concrete, wood floor etc) as Singing Magnets are not indestructible; they will break. Psycho-kinesics trick (mind over matter) : Place one magnet on a tabletop and the other underneath, directly below the one on top. By moving the hidden lower magnet, the top one appears to move mysteriously on its own, at the command of the "psychic controller" They are a great stress reliever! Caution: VERY STRONG magnets, not safe around pacemakers, credit cards etc |
