Pyrite Cube in original matrix. Natural formation of Pyrite crystal - perfect square. Approximate size including matrix of these specimens is approximately 3" x 2 1/2" x 1 1/2" Photo is representative of the pyrite specimen you will receive (some may have more than one pyrite crystal cube!
Great Mineral gift or earth science teacher resource.
Many believe in pyrite's metaphysical properties like promoting good physical health and emotional well-being. The name Pyrite comes from the Greek word "pyr" meaning "fire," and was named such because it was found that sparks would fly from it if struck against another mineral (best if Iron or Steel). In early times, this sparking ability gave man one way of creating fire; in later times, this ability made it popular for use in early firearms devices such as the wheel lock. Today Pyrite also carries the name of "Fool's Gold" for the simple reason that many throughout history have mistaken it for Gold because of its similar visible structure, metallic luster and brassy yellow color. Ironically, Gold is often found adjacent to Pyrite deposits, and the only thing foolish about finding "Fool's Gold" would be in not searching a bit farther! Pyrite is easily distinguished from Gold; Pyrite being lighter in color and much harder, whereas it cannot be scratched with a fingernail or knife as Gold can be. But even though Pyrite is a fairly hard mineral, its crystals are known to break and crumble, as it is brittle. Even though Pyrite contains a high percentage of Iron and is abundant, it is not used as a source for Iron (the primary iron ores being the Iron Oxides, Hematite and Magnetite), but it was mined as a source for Sulfur during WWII in order to produce sulfuric acid, an important chemical used in industry.

$29.99
Spectacular, diamond-like quartz crystals inside. From Morocco - easy to break, unlike typical domestic geodes. Approx size 2"-4" each. Set of 5 - some of the best on the market today Great party activity, party favor or classroom science activity. Kids and adults alike love this activity as they can break open a genuine geode (volcanic rock) which has beautiful crystals inside. Simply use a household hammer and lightly tap the geodes off-center, until they split. Great dinosaur party activity or crystal mining party activity. One of our favorite science teacher supplies. Size varies - approximate size is 2"-4" in diameter. These come from Morocco are are absolutely brilliant inside.
ID Chart - MOHS Hardness Scale - Rock and Mineral Collection
$19.99
Great earth science resource - Chart with samples on the Mohs Hardness Scale
Includes numbers 1-9 (all except diamond)
Specific samples included are Talc, Gypsum, Calcite, Fluorite, Apatite, Feldspar, Quartz, Topaz, Corundum
Wonderful for Science Fair presentations on Rocks, Minerals or Geology
The chart measures 8 1/2" x 5 1/4" with samples affixed to a sturdy card with ziplock protective plastic covering
Includes 9 genuine rocks/minerals/gemstones that are one through nine on the Mohs Hardness Scale. The Moh's scale of mineral hardness characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. It was created in 1812 by the German geologist and mineralogist Friedrich Mohs and is one of several definitions of hardness in materials science.
