Jadeite jade's gorgeous colors and rich, dense texture hard, beautiful sheen and transparency, good toughness, etc. are attributed to its characteristics of rock, mineralogical characteristics.The color of jadeite jade complicated causes, types more. We can from the jadeite jade's mineral composition, chemical composition features, and a UV-visible absorption of a near-infrared spectrum, such as experimental data to analyze and to the color of jade-colored the relationship. Jadeite is due to present the green with modest by the Cr3 +, is also a high-quality emerald green of the main reasons. Fe3+ and the role of Cr3+ different, the color of its mineral jadeite no substantive impact; Cr3+ is the emerald green color of the agent; Mn3+ can better explain the various jade and purple color of the causes of the spectral characteristics.Mineral particles shape, size and crystallization of the arrangement, cleavage and cracks, and other factors, is to determine the quality. Jade often a layer of the original stone weathering crust. Since the existence of weathering crust, which can not be observed within the emerald. Jade on the identification of the original stone was mainly through the observation of the weathered shell surface phenomena, the inference of the internal quality jade stone of the enclosures. Scientific research and concluded that the practice, jade stone of gambling under the enclosures and enclosures internal quality-close and have certain laws of relationship. A specific enclosures, certainly has the unique quality and types of internal-water color.Jade variety of colors, making the color grading and evaluation very difficult. This paper presents a systematic evaluation of ideas and programmes, the criteria are basically color to the color hue, saturation and brightness of colors based on three elements of standards. As the color of jade has a tremendous impact on prices, markets were filled with a large number of jade, emerald, we should clarify the causes on the basis of color, with special attention to natural jade and emerald stained the identification, so as not to draw erroneous conclusions.
