Speaking of ice beauty, people will think of ice and jade, the texture of ice and jade, like the ice in the snow, pure and thorough, warm and refreshing, with a hint of cool beauty. If you appreciate it carefully, you will find that it is like a clear spring, flowing with the vitality and hope of life. How much do you know about this kind of charm ice jade? The following is a small series of China Jewelry Merchants Network to teach you how to look at the ice jade? 1, look at the form: from the surface point of view, ice jade look like ice crystals, cool like water, giving people the feeling of ice and clear. 2, listening to the sound: knocking the jade body sound is a metal crisp sound. 3, look at the texture: ice jade looks like the pure and transparent quality of the glass, but it has three points of warmth, seven points cold, a transparent ice texture. In fact, ice jade is a kind of colorless or light-colored glass. The texture of ice jade is very transparent, but the impurities are slightly more, which is slightly worse than the glass. "The main characteristics of ice jade" 1. Cui nature: Whether it is jade raw material or finished product, as long as it is carefully observed on the polished surface, it is usually seen that the plaque-like interlaced structure is the same. 2. Density and refractive index: The emerald refractive index is about 1.66 (point measurement), while other similar jade are lower than 1.63. Moreover, the density of jadeite is large, and it sinks rapidly in tribromomethane, and similarly jadeite, serpentine jade, grapevine, quartzite jade, etc., are suspended or floated in tribromomethane. 3. Stone flower: There are small clumps in the jade, and the white fiber-like crystals with poor transparency are intertwined with stone flowers. 4, color: jade color is uneven, in the white, è—• pink, oil cyan, bean green background with a different shade of green or black. The difference between this stone flower and phenocryst is that the plaque is transparent, and the stone flower is slightly transparent to opaque. 5. Inclusions: The black mineral inclusions in the jade are mostly melted, the edges of the particles are loose and cloudy, and the green is deeper near the black inclusions. There is a saying of "green with black". 6. Gloss: The jade has bright luster and good polish, and it has a bright, soft and strong glass luster. "Ice Division Emerald Transparency Division" In general, the transparency of jadeite is called "head". The water head is long, and the water head is good in transparency. On the contrary, the water head is short, and the short head is the meaning of poor transparency. The transparency of jadeite is called “a few points of water†in the jewelry industry. One water means that the 3mm thick jadeite is translucent, and the "two waters" means that the 6mm thick jadeite is translucent. The jade with two waters represents the first level of the water head. It is necessary to pay special attention to the fact that when observing transparency, the intensity of light and the thickness of jadeite have a greater impact on it. Ice jade color evaluation standard Color is the first factor to evaluate jade. The standard to achieve good color is: positive, strong, positive, and average. Positive: refers to the range of tones, depending on the ratio of the primary color to the secondary color, that is, to be pure green, do not mix other colors. Concentration: refers to the depth of the color, in terms of emerald green, the concentration is preferably between 70% and 80%~ Yang: refers to the bright and bright color of jade color. The brightness of jade is mainly determined by the proportion of green and black or gray in jade. The green ratio will be brighter in color, and if it is black or gray, the color will be gray. In general, the more fresh the jade, the higher the value. Both: refers to the uniformity of the color distribution of jade.
