Knowing this, you are the crystal "identification expert"
Remember the Chinese aunt who was on the Internet in recent years? They are the international figures in the Wall Street Journal and are important figures in guiding the international gold price trend. All of this is inseparable from their understanding and investigation of the basic situation of gold, as well as the understanding of the concept of preservation and appreciation. So for crystal, what kind of crystal is a good crystal, can preserve the value, is it worth holding? Crystal quality assessment can be divided into four levels: 1, the top crystal This type of crystal is transparent, and permeability is one of the important metrics for testing crystal grades. The permeability of this type of crystal can be observed through a magnifying glass, such as no floc in the crystal, no impurities, no ice cracks, no scratches, and perfect work, then it belongs to the top crystal. 2, 3A crystal This kind of crystal is similar to the top crystal, and has a high degree of transparency. The naked eye can observe a very small amount of flocs or ice cracks, a small amount of scratches, exquisite workmanship, and almost perfect state. 3, 2A crystal This kind of crystal crystal is transparent and contains a small amount of floc, ice crack or other flaws, and it is excellent in workmanship. 4, A grade and below crystal This kind of crystal crystal is slightly turbid, with more flocs, ice cracks and other flaws. Good crystal should have the following characteristics: 1 The more intense the color, the higher the level We evaluate the quality of a crystal and generally start with its color, and the depth and uniformity of the color can be directly observed by the naked eye. In addition to white crystal, amethyst, pink crystal, citrine, etc., the color is not gray, brown, black and other colors as the evaluation standard, emphasizing the single purity of color. The color of amethyst is the top grade of purple and red, and the pink crystal is better. 2 crystal purity is good The method for judging the crystal crystal purity mainly depends on its inclusions. Except for the inclusion crystal, the less the inclusions, the higher the purity of the crystal. 3 singular price is expensive Generally, crystals containing impurities should not be purchased as much as possible, but if it is a naturally formed impurity shape, like a ghost figure crystal, such crystal collections have higher value and even higher value than similar crystals.
