The color of garnet is quite rich. What kind of color is the best? Garnet can be divided into five levels: color, clarity, transparency, finish, gloss and other professional dimensions. It can be divided into: AB, 2A, 3A, 4A, 5A. 5A is the highest level, the color is rose purple, the clarity is almost slight in the light transmission state, the transparency is in the light completely penetrated into the garnet, the light-transmitting part is purple, the gloss is bright, sharp and uniform. The impression is clear. Look at the garnet alone. The ice crack is the basic feature of the garnet. The other materials of the 5A grade can be pure, but the garnet is not even the pure 5A beads, that is, more or more. There will be some ice cracks or impurities, and the larger the diameter of the beads, the more the ice cracks or the impurities will be. The pure garnet bracelet is very small, and the price is more than a few thousand yuan. It is an impurity. Garnet is the most dense of all crystal materials, that is, the same size and size. Garnet is much heavier than other crystal materials. This is the simplest and straightforward way to judge whether it is true or false. The AB grade garnet is completely impenetrable, and the ice crack is too large to be seen clearly. 2A grade garnet is basically impervious, with many cracks in the ice, many internal impurities, and skin Grade 3A garnet is semi-transparent, with more cracks in the ice, some impurities inside, slightly skinned The grade 4A garnet is basically translucent, the ice crack is less than 3A, the internal basic impurities are less, and there is no skin. The 5A grade garnet is completely transparent, with little ice cracking, less internal impurities and no skin. The larger the bead diameter, the more ice cracks will be.
