Natural of sixty-two to one-hundred and twenty-five kilometers.

Natural gemstones come in
endless varieties. A natural gemstone is organic matter, a mineral, or a stone that
people generally use for jewelry as well as other things. Many of these
precious gemstones carry this mythology on healing properties and even magical
powers. A great amount of gemstones form inside of the Earth’s crust, which is the top layer of the
Earth. This outer layer of the earth has a depth of sixty-two to one-hundred
and twenty-five kilometers. There are only two gemstones (Peridot
and diamonds) that are created
inside of the Earth’s upper mantle, the process happens at a whopping depth of approximately
one-hundred to two-hundred kilometers below the surface.

            The first gemstone in the “Geo
Central Natural Gemstone Kit” would be Quartz. Since the olden days Quartz has
been one of the most favored gemstones. Quartz is the most diverse of all the
minerals, created in all different forms, hues, and habits. The chemical
formula is SiO2 and its hardness is a seven on the Mohs scale. The mineral
Quartz has many variances, amethyst is just the purple type. The coloration of this mineral varies from
a light pink/violet to a dark blue/violet as well as other hues. Most of the
time the hues are almost spotty, and the color intensifies at the head of the
crystals. This beautiful mineral owes its colors to potent radiation, such
as gamma rays derived from radioactive origins. Rose
quartz is variance of quartz which has a pale pink to rose red color. Unlike
Amethyst the color is usually considered as due to trace amounts of titanium,
iron, or manganese. Seven in the
hardness scale and its fracture is conchoidal. Carnelian is an orange-colored mineral that is also part of the Quartz
family. It ranges from orange to a rusty brown hue, although it is popularly
known for its intense orange and red/orange crystals. The Carnelian name
originated from a Latin word signifying flesh. It has a
hardness of 6.5 to 7. Another form of Quartz being Red jasper, it contains fine grain and often varies in
patterns that are formed from minerals and other organic matter within the
stone. If you go ahead and Scratch Red
Jasper with a knife it will not be marked for the reason that is a seven on the
Mohs hardness scale. During tectonic
activity cracks fill up with jasper this happens many times therefore the
cracks will reopen again causing jasper to shatter, filling the voids in between
with more jasper. This leads to the formation of Brecciated jasper. Picture
Jasper is another quartz family mineral. It is composed mostly of
cryptocrystalline silica. It has an abnormal
amount of impurities, mainly iron oxides, these impurities being the reason for
the stones large variety in different hues and pattern, and has a hardness of
6.5 to 7. Blue Dalmatian Jasper is an aggregate of micro quartz and is a course variety of silica, although the name is Blue
Dalmatian Jasper it is mostly red, yellow, brown hues and rarely blue. The red
color is most common and the reason for that is because of its iron inclusions.
Iron ores are significantly important for the production of iron. Mostly all
Earth’s major iron ore deposits are in rocks that formed over 1.8 billion years
ago. Hematite is an iron oxide with a chemical composition of Fe2O3. It has vast variety of uses because of its iron ore.
The mineral produces pigments, radiation shielding, ballast, and more. Amazonite (KAlSi3O8) is a unique green variety of
microcline, which is the low temperature pure potassium member of the alkali
feldspar group. Amazonite’s hue is
believed to be caused by trace impurities of lead and OH-1. Sodalite minerals are chemically alike feldspars but
have much less silica, forming from alkali-rich silica-poor melts therefore it is
a member of the feldspathoidal group. The hue of Sodalite is a rich dark blue.
Howlite name comes from a Nova Scotia geologist who discovered it, being Henry
How. This mineral can easily imitate the mineral turquoise. Howlite is white or
gray however it can take in dyes very easily, therefore people dye it a
turquoise blue to get a better profit. In the hardness scale it is a 3.5. Turquenite is commonly known as the blue version of
Howlite because of how similar they are to Turquoise. Turquenite gemstone
mythology is that it can help treat teeth and bones. It also supposedly helps
people be more informed up their past lives by opening up the third eye
releasing important memories during the previous lifetimes.Tiger’s eye has
a variety of macrocrystalline quartz but is really a ‘pseudomorph’ of quartz. A
‘pseudomorph’ is what geologists believe to be any mineral that morphs into
another mineral. Tiger’s eye started out as crocidolite and later converted
into quartz. The “metamorphosis” of tiger’s eye starts with quartz slowly
becoming embedded within fibers of crocidolite, leading to the quartz
completely replacing crocidolite while still keeping the original fibrous form.
Orange Calcite has a chemical formula of CaCO3. It is normally white but also colorless, gray, red, green,
blue, yellow, brown, orange. It is most
commonly used in construction, they need calcite in the form of limestone and
marble to make cement and concrete. The following is Rhodonite which is a manganese chain silicate and part of the
Pyroxenoid group of minerals. It is most commonly formed in massive or granular
habits, compact groupings, coxcomb aggregates. It is usually a rosy pink but
sometimes is a brownish red. Rhodonite is
known as an emotional healer gemstone and helps balance you during stressful
times. Unakite Jasper name coming from
the Greek epidosis meaning “growing together.” It is said to best used for
lasting love, a common custom is to place Unakite  in a sealed bag as a marriage or commitment
symbol. Next is jade, Jades past history dayes back many years it was first
used to create weapons and tools because of how tough it is. The Mayans and
Aztecs were especially fond of this gem and the name means “piedra de
ijada” in Spanish translating to “stone for the pain in the
side”. It was believed to cure illnesses because Central America would
hold pieces of jade to their sides. Another popular gem would be Snowflake Obsidian also known as nature glass, which
is made when the felsic lava from a volcano cool very quickly thus forming the
minimum crystal growth.
