THE COLORS AND VARIETIES OF GARNET
WHAT IS A GRANATE?
Garnets refer to a set of minerals related to each other, each species of garnets has physical characteristics that relate it to each other in turn, it also has the same crystalline form.
They have a different chemical composition, it belongs to the group of nesosilicates.
The atomic bonds of garnets are varied so their chemical composition as well.
La knorringita es un tipo de granate compuesto de magnesio y cromo. Knorringita pura del miembro del extremo nunca ocurre en la naturaleza. Es utilizado como indicador mineral en la búsqueda de diamantes.
It is characterized by being one of the most changeable garnets. Its chemical formula is Ca3Al2 (SiO4) 3 Calcium can be replaced by ferrous iron and aluminum by ferric iron. Pure Grossular is colorless; the wide range of colors in this one. Garnet is caused by various impurities.
transparent variety of
It is a grousel that is green in color. It is colored
by chromium and / or vanadium.
Is a yellow-green variety of grossular with a slight overlap in the grossular andradite series
Garnet is the green, pink, grayish-white to bluish variety of grossular
Almandine Garnet Crystal with Muscovite crystals on the side. Known for being the best known of the garnets. The formula of almandine glass is: Fe 3 Al 2 (SiO 4) 3. Magnesium is the one who replaces iron with substances that are increasingly rich in compliments. Composition. Almandine color range from dark red to black. It is often cut with a convex or cabochon face, and is later known as a carbuncle.
Much of its origins occur in typically peridotite ultamafic rocks of the Earth's mantle: these mantle-derived peridotites can be attributed to igneous and metamorphic processes.
Garnet is the red-orange variety of pyrope-espesartite. It was discovered in 1970 in Kenya as a by-product of rhodolite.
Its composition can vary in different ways and can be red, yellow, brown, green or black. Characterized for being the brightest of garnets and has several varieties of hard stones. Andradite occurs in skarns developed in contact with impure limestone metamorphosed igneous calcic rocks; in chlorite schists and serpentinites and in igneous alkaline rocks (typically titaniferous
Subject to whether the Y or X component in the type's chemical composition is insistent, they can be derived from the two groups of the garnet family
These derived groups have their own characteristic chemical composition. then we will see the aforementioned
-Andradita (silicato de calcio y hierro)
Pyrope (magnesio aluminiosilicato)
-Grossular (silicato de calcio y aluminio)
-Almandina (silicato de hierro y aluminio)
-Uvarovita (silicato de calcio y cromo)
-Espessartita (aluminio manganeso silicato)
Es imposible encontrar un granate piropo con una composicion quimica pura. En lugar de durante el crecimiento, otros elementos, presentes en el derretimiento del cual creció el piropo
When iron (as seen in almandine, above) is mixed during the growth of a garnet pyrope, an aluminum magnesium-iron silicate would be obtained.
When there is an abundance of magnesium in the chemical composition, it is a compliment.
