Hello Dear Steemian, Today i will share you a familiargemstone used by ancient for treatment, i will explain Scientifically how this gems can use for treatment, , , ,

Amethyst

Amethyst is a very popular gemstone, its purple color can make people our eyes fascinating, and this gemstone also has a high value and demand by many collectors. Some people believe this gemstone can provide protection for its users, such as peace, strength, intelligence, and spiritual. Some others believe this gem can attract the love of a woman, but this is only for the believer ;). Before i discuss about amethyst stone, let us know a bit story about Amethyst gemstone in era of Egyptian ancient.

The ancient Egyptian society believed this gemstone can provide protection for Kings tombs, in the middle of century the gemstone used for treatment, intelligence and protect the user from black magic, in the era of ancient roman the gemstone used to prevent drunkenness, by insert this gems into wine glass.

Lets to Solve This Matter In Science Explain

Chemically, amethyst gemstone is quartz mineral compounds composed of Silicon and Oxygen with chemical formula SiO₂. The purple or violet color of this gemstone due to chemical impurities, the impurity is Trivalent Iron (Fe₃₊). The concentration of ion Fe³⁺ in the gemstones can affect it color, either purple or dark purple, it depend on iron concentration. Because the color affected by impurity, so the chemical formula for Amethyst is ἀ-SiO₂, where the ἀ- is impurity, in chemical formula we can write as follow :

Fe³⁺ + SiO₂ => ἀ-SiO₂

The ἀ- is trivalent iron which give the color effect for quartz mineral, SiO₂ is a Quartz or Silica, when the trivalent iron (Fe³⁺) bind to the quartz (SiO₂ or silica), it change color to the purple, so it called as Amethyst.

What is Quartz ?

Quartz is a mineral formed from silicon (Si) and oxygen (O₂), it can form at any mineral temperature and it resistant of weathering (corrosion), so the quartz can be found in mountains, beaches, rivers and deserts and it also can be found in metamorphic, and igneous rocks. Quartz is a natural mineral, it has hardness of 7 mohs scale and used for lens manufacture and laser cover.

Chemically, Quartz and Silica are same, it composed of silicon and oxygen, silica can to produce silica gel, it is grain glass with the pores, silica gel can be synthesized with Sodium Silicate, although its name "gel" but it was hard like a glass, i have explain this before how i made it from Bagasse. But I review a bit about it cluster named with siloxane (Si-O-Si), silica gel has a siloxane group, this group in Silica Gell serves as an absorber, silica gel can absorb moisture and also toxic gas. its ability in absorption due to siloxane group, it can survive until heating temperature below 600^oC.

Chemistry Answer Scientifically

Mineral quarts can formed at any mineral temperature, the synthetic of Amethyst gems can be formed at hydrothermal grow or high-pressure autoclave temperatures. Naturally, the forming of Amethyst precious gemstone also occurs at high temperatures and pressures. When Quarts begin to melt and mix with trivalent iron (Fe³⁺) elements, so, the process changes from quartz to amethyst, When it have been cool, the mineral begins to be harden and occur color change, the basic element of Amethyst forming is silica (quartz). Where the silica also contain the siloxane that serve as absorber, so this was reasonable if the ancients insert the Amethyst gemstone into wine glass to prevent drunkenness, because amethysts with siloxane (cluster) also has function as an absorber.

Conclusion

The purple color of amethyst gemstone caused by chemical impurity, Amethyst gemstones there were formed naturally and synthesis, to synthesize amethyst should to use high temperature.
