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

Natural gemstones come inendless varieties. A natural gemstone is organic matter, a mineral, or a stone thatpeople generally use for jewelry as well as other things. Many of theseprecious gemstones carry this mythology on healing properties and even magicalpowers. A great amount of gemstones form inside of the Earth’s crust, which is the top layer of theEarth. This outer layer of the earth has a depth of sixty-two to one-hundredand twenty-five kilometers. There are only two gemstones (Peridotand diamonds) that are createdinside of the Earth’s upper mantle, the process happens at a whopping depth of approximatelyone-hundred to two-hundred kilometers below the surface.

            The first gemstone in the “GeoCentral Natural Gemstone Kit” would be Quartz. Since the olden days Quartz hasbeen one of the most favored gemstones. Quartz is the most diverse of all theminerals, created in all different forms, hues, and habits. The chemicalformula is SiO2 and its hardness is a seven on the Mohs scale. The mineralQuartz has many variances, amethyst is just the purple type. The coloration of this mineral varies froma light pink/violet to a dark blue/violet as well as other hues.

Most of thetime the hues are almost spotty, and the color intensifies at the head of thecrystals. This beautiful mineral owes its colors to potent radiation, suchas gamma rays derived from radioactive origins. Rosequartz is variance of quartz which has a pale pink to rose red color. UnlikeAmethyst the color is usually considered as due to trace amounts of titanium,iron, or manganese. Seven in thehardness scale and its fracture is conchoidal.

Carnelian is an orange-colored mineral that is also part of the Quartzfamily. It ranges from orange to a rusty brown hue, although it is popularlyknown for its intense orange and red/orange crystals. The Carnelian nameoriginated from a Latin word signifying flesh. It has ahardness of 6.5 to 7. Another form of Quartz being Red jasper, it contains fine grain and often varies inpatterns that are formed from minerals and other organic matter within thestone. If you go ahead and Scratch RedJasper with a knife it will not be marked for the reason that is a seven on theMohs hardness scale. During tectonicactivity cracks fill up with jasper this happens many times therefore thecracks will reopen again causing jasper to shatter, filling the voids in betweenwith more jasper.

This leads to the formation of Brecciated jasper. PictureJasper is another quartz family mineral. It is composed mostly ofcryptocrystalline silica. It has an abnormalamount of impurities, mainly iron oxides, these impurities being the reason forthe stones large variety in different hues and pattern, and has a hardness of6.5 to 7. Blue Dalmatian Jasper is an aggregate of micro quartz and is a course variety of silica, although the name is BlueDalmatian Jasper it is mostly red, yellow, brown hues and rarely blue.

The redcolor 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 allEarth’s major iron ore deposits are in rocks that formed over 1.8 billion yearsago. 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 ofmicrocline, which is the low temperature pure potassium member of the alkalifeldspar group. Amazonite’s hue isbelieved to be caused by trace impurities of lead and OH-1. Sodalite minerals are chemically alike feldspars buthave much less silica, forming from alkali-rich silica-poor melts therefore it isa 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 HenryHow. This mineral can easily imitate the mineral turquoise. Howlite is white orgray however it can take in dyes very easily, therefore people dye it aturquoise blue to get a better profit. In the hardness scale it is a 3.

5. Turquenite is commonly known as the blue version ofHowlite because of how similar they are to Turquoise. Turquenite gemstonemythology is that it can help treat teeth and bones. It also supposedly helpspeople be more informed up their past lives by opening up the third eyereleasing important memories during the previous lifetimes.Tiger’s eye hasa variety of macrocrystalline quartz but is really a ‘pseudomorph’ of quartz. A’pseudomorph’ is what geologists believe to be any mineral that morphs intoanother mineral.

Tiger’s eye started out as crocidolite and later convertedinto quartz. The “metamorphosis” of tiger’s eye starts with quartz slowlybecoming embedded within fibers of crocidolite, leading to the quartzcompletely 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 mostcommonly used in construction, they need calcite in the form of limestone andmarble to make cement and concrete.

The following is Rhodonite which is a manganese chain silicate and part of thePyroxenoid group of minerals. It is most commonly formed in massive or granularhabits, compact groupings, coxcomb aggregates. It is usually a rosy pink butsometimes is a brownish red. Rhodonite isknown as an emotional healer gemstone and helps balance you during stressfultimes.

Unakite Jasper name coming fromthe Greek epidosis meaning “growing together.” It is said to best used forlasting love, a common custom is to place Unakite  in a sealed bag as a marriage or commitmentsymbol. Next is jade, Jades past history dayes back many years it was firstused to create weapons and tools because of how tough it is. The Mayans andAztecs were especially fond of this gem and the name means “piedra deijada” in Spanish translating to “stone for the pain in theside”. It was believed to cure illnesses because Central America wouldhold pieces of jade to their sides.

Another popular gem would be Snowflake Obsidian also known as nature glass, whichis made when the felsic lava from a volcano cool very quickly thus forming theminimum crystal growth.
