Tanzanite, a unique stone in the world Tanzanite is considered as one of beautiful and precious stone in the world. Tanzanite loose stones are unique all over the world and first choice of stone lovers. Its undeniable beauty thanks to its color that goes from ultramarine to a sapphire blue and its scarcity began to attract the attention of the great jewelries. Despite its beauty and scarcity in the world, it is not part of the four most precious gemstones; diamond, ruby, sapphire and emerald. But it could perfectly be, since this stone is only located in an area near Kilimanjaro in northern Tanzania. Its value grows every year as there is a high demand and there are fewer and fewer active deposits of Kilimanjaro in northern Tanzania. As its name did not consider it very interesting since it caused confusion with a word in English, they decided to exchange it for Tanzanite, the Tanzanian stone. Best about the Tanzanite stone Because crude tanzanite, without heating or polishing, is usually a reddish brown hue, unattractive to the human eye. So it was not until the fire, mentioned above, that it reached more than 600º Celsius and became the striking color that today represents it.Violet gemstones are also very rare in the world. Tanzanite is characterized by a strong variety of colors, ranging from synthetic star sapphire blue, violet or even green. Regarding its clarity, it is a transparent gem. Its hardness, of 6.5 on the Mohs scale, which measures the hardness of minerals. Hardness is the opposition offered by materials to alterations such as abrasion, penetration, and shearing, scratching, and permanent deformation.Whitetopaz price is very high like the Tanzanian stone. This scale of measurement was created by the German geologist Friedrich Mohs in 1982. We could say that the scale of Mohs is a relative and quantitative scale, consisting of 10 minerals as a reference ordered from 1 to 10. If one compare rhodolite garnet value with this stone then it is hard to define which is better. The first mineral on the list, which occupies the number one position, is talcum, and places it as soft mineral, and in 10 is the diamond, the hardest mineral. In this scale, we can easily diagnose how to establish a hardness parameter since if the mineral can be damaged or scratched with the nail, we can say that it will be in the first or second position along with talc or gypsum. If you can do it with a copper coin, we are talking about the third step of the scale. For the fourth and fifth positions it will be necessary to use a knife. In position number six, the mineral could be damaged with a steel file, in the next step with a crystal. Going up to the hardest minerals we find as resistance in the eighth position they can only be scratched with tools with tungsten (chemical element of atomic number 74), in position nine we find minerals like the best cubic zirconia that can be damaged, scratched or modified by the Silicium carbide.
