    Since 1803, this name has been applied not to one, but to a whole group of minerals that have similar properties and composition.

    In the 17th and 19th centuries, garnet jewelry became extremely popular in Europe.

    Description of mineral

    So, grenades are a group of minerals of silicate class, united by a common type of their crystal structure with isolated tetrahedrons( faces of square shape).

    All of them have valuable physical properties - high mechanical strength, thermal and chemical resistance, the ability to reduce the speed of sound at the time when a sound wave passes through them. However, despite the identity of physical and chemical properties, the color scale of these precious stones is different - red, black, yellow and even green. It is determined by the chemical composition of the crystal.

    It should be noted that only some varieties of garnets are precious stones, while others are not at all suitable for jewelry business. Initially, for jewelry used only "pyrope" - stones of a noble dark red color.

    Chemical composition and physical properties of garnet

    A group of minerals called garnets are divided into two separate subgroups:

    1. Iron-magnesian-manganese piralspit( these include almandine, pyrope, spessartine).
    2. Calcium urandites( these include grossular, uvarovite, andradite).
    3. loading. ..

    Each of these types of garnets has certain physical properties and chemical composition, but they are united by the general formula: R2 + 3 R3 + 2 [SiO4] 3, where R2 + is magnesium( Mg), iron( Fe), manganeseMn), calcium( Ca);R3 + - aluminum( Al), iron( Fe), chromium( Cr).

    Elementary cells of garnet crystals have a cubic structure. Connecting, they form closed twenty-four-sided( tetra-giothreectahedra) and rhombododecahedrons - crystals consisting of 12 rhombuses.

    The hardness of this group of minerals ranges from 6.5 to 7.5 on the Mohs scale, and the density is from 3830 to 3930 kg / m3.

    How to distinguish natural garnet from forgery

    Granate is forged very rarely, because at its cost synthetically grown garnet is more expensive than natural stone.

    However, if you doubt the authenticity of the garnet product, you can conduct a small experiment based on a mineral property such as light magnetism.

    For him you will need:

    • accurate scales,
    • magnet;
    • cork.

    Stages of the experiment:

    1. Put pomegranate on the scales on the plug( to exclude the contact of the mineral with the metal).
    2. We remember the exact weight of the stone.
    3. Place a magnet close to the stone( at least 1 cm apart).
    4. Observe the balance arrow: under the influence of mineral magnetism, the pointer of the balance should begin to oscillate.

    This is a fairly reliable way to make sure that the garnet is real. But the most accurate definition of a forgery is possible only with the help of a special device - binolupy.
