Hematite
 Fe2O3
 Minnesota, Michigan, Wisconsin, and
Canada
 found in volcanic rock and veins
 forms near water to form "blueberries" like
those found on mars

Garnet
 Si,O combined with Ca, Mg, Fe, and Al
 Sri Lanka, South Africa, Virginia, California,
and Brazil
 Igneous and metamorphic rock. sometimes
found in altered rock and metamorphasized
limestone
 Closely related to silicate minerals and
often misclassified as a gem. Precious
garnet is often found near diamonds in the
"blue earth"
Garnet
Magnetite
 Fe3O4
 Colorado
 basic igneous, metamorphic and
sedimentary rock
 Only black ore that can easily be picked up
by a magnet
Magnetite
Potassium Feldspar
 All are aluminum silicates (Al,Si) formed
with K, Na, or Ca
 North Carolina
 found in almost all igneous rocks and rocks
created from them
 Feldspars are the most abundant minerals
in the world, making up 60% of the Earth's
crust. they are used mostly for ceramic
glazes, flux enamels, and binders
Potassium Feldspar
Silver
 Ag (natural element) is often found in long,
twisted, branched clumps and in Ag2S
compounds
 Western US
 Natural Element
 Often a valuable bi-product of lead, zinc,
and other metal smelting
Silver
Copper
 Cu (natural element) is most often found as a
compound then smelted from its ores (CuS,
CuFeS, CuO, CuAl, Cu2Co3(OH)2)
 Chile, Peru, Cyprus, Democratic Republic of
Congo, South Africa, Russia, and Australia. In the
US, the southwest is most abundant
 Natural element found most commonly in and
near the veins of volcanic rocks. Some compounds
can be formed by oxidation of the Cu.
 Electrically conductive-often used for electricity.
Copper
Gold
 Au (natural element)
 Mostly found in South Africa but some is mined in
South Dakota and Nevada (western US)
 Natural element found in quartz veins, sometimes
found with pyrite. Can also be found in
metamorphic rocks and as deposits in
sedimentary rocks
 Very soft-often alloyed with Cu to make it harder
and spread it further in jewelry
Gold
Project
 Grow crystals using “space growth kit”
 When crystals are formed, create a piece of
wire jewelry to complement your stones
 Hypothesize which elements created your
gems, and what gems they may be
 Discuss hypothesis and results with the class
