Jionova Hair Jewels processes high-quality colored gemstones. Gems, that is minerals, can be formed in very different ways.
Formation
Gemstones, that is minerals, usually emerge under great pressure from molten smelting and gases deep in the interior of the earth. By volcanic eruption they reach the earth’s surface with the lava and crystallize.
Jionova Hair Jewels zeichnet sich durch die Verarbeitung von exklusiven, qualitativ hochwertigen Farbedelsteinen aus. Edelsteine, also Mineralien, können auf ganz unterschiedliche Weisen entstehen.
Illustration 1:
A volcano erupts and forms a cone. This happens very fast. It is believed that the transport of the gems to the surface of the earth takes place within a few hours. The gradual pressure equalization of a regular volcanic eruption, in which hot magma magenta slowly emerges from great depths to the earth’s surface, the gems would not withstand. Rather, they would disaggregate into graphite worthless for gemologists. Therefore, geoscientists have long suspected that kimberlites are special volcanic eruptions in which magma rises from the mantle to the surface within a very short time.
Illustration 2:
Due to the weather, the volcanic cone gradually erodes.
Illustration 3:
Due to vegetation, an external overlap often takes place and thus levels the cone.
Illustration 4:
In opencast mining, the filling of the vent is processed, in underground mining tunnels are processed.
Hardness
There are different types of hardness with gemstones.
More than 150 years ago, Viennese mineralogist Friedrich Mohs (1773 – 1839) introduced the term „scratch hardness“ with minerals. Mohs defines it as the resistance of a mineral to being scratched by a sharp object. To date, Mohs‘ hardness scale with 10 minerals different in hardness has been widely used as a comparison scale throughout the world.
Number 1 stands for the softest and number 10 for the hardest grade. A higher-degree mineral always scratches a lower-graded one, equally hard minerals do not scratch.

Color and lighting effects with colored gemstones
With gemstones, color has priority, whereas with diamonds it is weight or purity.
However, color alone does not yet identify the stone. There are many gems of the same color, and there are some gems that come in different colors – for example, tourmaline and peridot are both green. Tourmaline is available in other colors: in addition to innumerable shades of green (light mint or petrol green up to dark green), it can also be pink, rose, yellow or brown. Peridot, however, has only been found in the colors yellow green, olive green and brownish.
Colored gems impress by fascinating light reflections. There are gems that have different colors or depths in different directions. As soon as two major colors are visible, it is referred to as dichroism, with three colors it is called trichroism. The term pleochroism is used as a collective term for both species.
