Making rocks into magnets The most magnetic and common type is a lodestone. It consists of a brownish-black mineral called magnetite. Lodestones are natural compasses: Suspend one by a thread or wire and it will rotate until its magnetic field is aligned with Earth’s magnetic field. A magnetic field is the area around a material in which its magnetic forces can be detected.

Geode Inside and outside views of the geode. Geodes (Greek γεώδης - ge-ōdēs, earthlike) are geological secondary structures which occur in certain sedimentary and volcanic rocks.ost geodes contain clear quartz crystals, while others have purple amethyst crystals. Still others can have agate, chalcedony, or jasper banding or crystals such as calcite, dolomite, celestite, etc. There is no easy way of telling what the inside of a geode holds until it is cut open or broken apart.

Magnetite Although other metallic minerals may mimic magnetite’s color, luster, hardness and specific gravity, magnetite is the only common mineral that is magnetic. So a magnet is usually all that is needed to identify its presence. Magnetite crystals usually only occur when magma cools slowly enough for crystals to form and settle out of the magma.

- Magnetite is a natural magnet! Part of a mineral group called the oxides, magnetite can usually be identified by its strong magnetism and dark color. Magnetite is often not very abundant, but it can be found in many different types of igneous, metamorphic, and sedimentary rocks.

- Dolerite is a volcanic rock. While similar to basalt, it contains crystals which can be seen with a hand lens. This indicates that it cooled a little more slowly than basalt.Typically it is found in volcanic plugs which channeled the basalt to the surface.Erosion since Tertiary times, 60 million years ago, has exposed these plugs.hile similar to basalt, it contains crystals which can be seen with a hand lens.

What is Lodestone? You can also feed your lodestone bits of iron shavings or magnetic sand-and this will come in handy for spellwork. The shavings often look like bits of metallic hairs when they come in contact with the lodestone. In many traditions of hoodoo and folk magic, a lodestone is used to attract money.

Difference Between Magnetite and Hematite Magnetite and hematite are minerals of iron. Both have iron in different oxidation states, and they are in the forms of iron oxides.owever, all these types of hematite minerals have the same reddish brown streak. In fact, hematite got its name because of the blood red color it has when it is in the powder form. On the Mohs scale, its hardness is given as 5-6. Hematite is brittle, but it is harder than pure iron.

Facts and History of the Compass Earliest compasses were made of lodestone, a particular form of the mineral magnetite. The first compass was a lump of lodestone that was tied to a rope and left to hang freely. Other were also made from lodestone but were shaped like a spoon or a ladle whose handle was made to point south.

The Gemstone Sunstone Sunstone is an interesting feldspar gemstone with a glittery appearance and usually an orange or reddish color, hence its name. The glitter effect is caused by inclusions of the mineral Hematite, or sometimes also Goethite or Pyrite (and in one rare instance, Copper).unstone is very similar in habit to Aventurine, a form of Quartz that exhibits the same glittering Aventurescence effect. Sunstone is occasionally called 'Aventurine Feldspar' to distinguish it from its Quartz counterpart.

Geodes The term geode is derived from the Greek word Geoides which means earthlike.. A geode is a round rock which contains a hollow cavity lined with crystals. Rocks which are completely filled with small compact crystal formations such as agate, jasper or chalcedony are called nodules. The only difference between a geode and a nodule is that a geode has a hollow cavity, and a nodule is solid. Geodes begin as bubbles in volcanic rock or as animal burrows, tree roots or mud balls in sedimentary rock.

THE MINERAL NATROLITE Natrolite is a common and popular zeolite mineral. Its radiating sprays of ice clear acicular crystals are not exclusive to natrolite but they are a hallmark of this mineral. Natrolite can make a fine specimen in itself but it often is an accessory to other minerals and can enhance the beauty of associated minerals such as apophyllite, heulandite, benitoite and others.

What are magnets made from? Magnets are made from a rock called magnetite. For example we will take a bar magnet it is made up of tiny bar magnets, they are called magnetic domains. Magnetic domains only exist in special kinds of metals such as iron, nickel and cobalt. Other metals like aluminium or copper don't have magnetic domains.

Where is magnetite found and how is it extracted from earth or refined so it can be used? HELP ASAP? Magnetite is a ferrimagnetic mineral with chemical formula Fe3O4, one of several iron oxides and a member of the spinel group. The chemical IUPAC name is iron(II,III) oxide and the common chemical name ferrous-ferric oxide.

- Solid Geodes are referred to as Nodules. The interior of hollow geodes are filled with mineral crystals, which grow inward from the rind into the hollow space inside the geode. Most often, geodes found in Kentucky are lined with quartz crystals. Less commonly, the calcite or dolomite crystals are found on the. inside, either alone or associated with bitumen, barite, galena, fluorite, quartz, limonite, sphalerite, pyrite, selenite, or celestite.

What in the World is a Geode? Like a cave, the mineral rich solution that leaves crystals behind inside a geode is a naturally occurring process between groundwater and the surrounding rock. Crystal size, color and chemical composition will vary and each individual geode is unique.Clear quartz, smoky quartz, amethyst, calcite, celestite, and chalcedony are examples of some minerals you may find inside a geode. Geodes from the same location often have the same type of mineral crystals.Some geodes are filled in with beautiful layers of mineral crystals.lear quartz, smoky quartz, amethyst, calcite, celestite, and chalcedony are examples of some minerals you may find inside a geode.

The Mineral diamond The hardness and refractive index may slightly vary among Diamond specimens. Bort and Carbonado exhibit a slightly lower hardness than other Diamonds, and lack cleavage. Lonsdaleite (also known as Hexagonal Diamond), is a type of Diamond found with meteorite s and is of extraterrestrial origin.ISTINGUISHING SIMILAR MINERALS. The only mineral that can possibly be be confused with Diamond is waterworn Quartz pebbles which may resemble waterworn Diamonds, but the hardness and luster of Diamond will easily differentiate the two.
