Chow Tai Fook's brand is still no problem, generally there will be no fakes, but now many of them are not real Hetian jade producing areas, and many of them are broad Hetian jade series.
How to identify the authenticity of Chow Tai Fook Jade?
1. fineness: fineness is a very important quality index of any jewelry and jade. Fine density determines the jade quality of jade material and whether it is comfortable or not. Jade with good color feels delicate and sticky to the naked eye. Some collectors describe the delicate and moist jade as steamed glutinous rice cakes. The internal structure of jade with good color should not be obvious, but the structure can be seen with a professional flashlight. The finer the structure, the better the quality. If the structure is thicker with the naked eye, the texture is not good. You can't see the internal structure when you look at it with a professional flashlight or with a magnifying glass 10 times. It may not be jade. Jade seed material with almost no structure is the best.
2. Purity: The main factors affecting the purity of jadeite include cracks, spots (black, brown, white), waterline and other impurity minerals. Brown impurity minerals, white impurity minerals, waterline, etc. Common in white jade, aquamarine and sapphire, black spots and green spots impurity minerals are common in jasper.
3. Hardness: According to the data provided by professional organizations, the hardness of jadeite is generally 6 ~ 6.5 degrees Mohs, and a few can reach 6.9 degrees. The hardness of Russian materials belonging to jade series is slightly lower, the hardness of Qinghai materials is slightly lower, and the hardness of Korean materials is even lower. The hardness of Hetian jade, sapphire and jasper in Xinjiang is generally higher than that of white jade and topaz, and the hardness of seed material may be higher than that of mountain material. Hardness determines the brightness of polished jade after processing, and the material is too soft to produce the crystal beauty of jade.
4. Permeability: Generally speaking, high permeability is also called head foot. Although the water head is enough to set off the texture and color of jade, not all jade with high transparency is good. Jade pays attention to the implicit beauty, that is, moderately transparent and translucent. Although it can penetrate the light, it can't see the object clearly. This transparency enhances the moist feeling of jadeite luster.
5. Moisture: The moisture of jade is related to the mineral composition and structure of jade materials. Fine structures will become moist and soft. Jade luster belongs to oily luster, which is very soft, neither thick nor light, that is, there is no crystal inspiration of strong light and no wax texture of weak light.
6. Color: In the evaluation of jadeite, color type is a very important factor. Generally speaking, suet jade, white jade and topaz are the best, followed by jet and jasper, followed by sugar jade, sapphire and sapphire. No matter white jade or jasper, good quality jade requires positive color tone, no color difference, uniform color distribution, and jasper's green color should have a certain saturation. In addition, when jade has more than two colors, such as leather color, sugar color and emerald color, the colors are well matched and the pretty color is ingenious and novel, which can add a lot of color to the work and even double its value.
7. Craft: As the saying goes, a good craft design is very important for jadeite. This technology mainly includes two aspects: theme design and processing technology evaluation. The deeper the subject matter, the finer the processing technology, the deeper the effort, the more time-consuming and laborious, and the higher the value naturally.
