Evaluation standard of quality grade of jade jewelry

China's first quality inspection standard for high-grade jadeite, Quality Grade Evaluation Standard for Jade Ornaments1/KLOC-0, passed the evaluation in Yunnan on March 3rd, and China's first Quality Inspection Certificate for High-grade Natural Jade Ornaments, known as the "passport" for jadeite, also appeared in Kunming. Deng Kun, director of the institute, said that jadeite has had a corresponding value standard since then.

The standard breaks through the division of quality grades, and divides natural jadeite into "five grades and twelve products" such as top grade, treasures, fine products, excellent products and qualified products. In addition to qualified products, each grade is divided into three grades, which are evaluated in detail from five aspects: texture, transparency, color, technology and comprehensive impression. Using the "five plus one scoring method" with a thousand points system, the specific overall picture of jade ornaments is assigned to specific quality intervals. It makes up for the defect that the grade evaluation of high-grade jade can only test the authenticity, but can not explain the quality and high-grade degree. In addition to including the quality into the evaluation criteria, the Jade Quality Inspection Certificate will also describe the details of previous transactions, and describe its appearance and technology in detail, that is, consumers can see the representative significance of jade, the related culture it contains, the number of transactions and other more humanized contents.

The Quality Grade Evaluation Standard of Jade Jewelry was drafted by Yunnan Jewelry Quality Supervision and Inspection Institute after market research and combined with the needs of enterprises and consumers, which lasted more than one year. 1/kloc-0 passed the evaluation of Yunnan provincial bureau of quality and technical supervision on March 3rd and became the local standard of Yunnan province.

"The grading of jadeite is an important prerequisite for standardizing the jadeite market. However, due to the influence of jadeite color, variety and expensive samples, the grading of jadeite has always been a difficult problem in the industry." Zhang Weihe, honorary vice chairman and appraiser of Yunnan Jewelry Association, said that the new standard evaluation concept meets the needs of humanization, and the jade quality inspection certificate is clear at a glance, which has important guiding significance for consumers to distinguish high-grade jade from qualified products, and will promote jade consumption and promote the development of jade industry.

In addition, the new standard brings the cultural meaning of jadeite into comprehensive evaluation, and also changes the concept that only green jadeite is high-grade jadeite, including the identification of jadeite in all colors. This is also the first in China, which is of great significance to promote Yunnan Province to take the lead in realizing the standardization, standardization and internationalization of the jade industry.

Yunnan Province, bordering Myanmar, has always been the hub for jadeite to enter China. Almost all jadeite products, semi-finished products and rough stones sold to the mainland and coastal areas are re-exported from Yunnan. At present, there are more than 600 businesses dealing in jadeite rough stones in Yunnan Province, with an average annual turnover of about 50 million US dollars, reaching 200 million US dollars at the peak. According to the data, 70% of the rough stones, 20% of the finished products and 10% of the precious stones or semi-finished products leave the province every year.

The advantages and disadvantages of grade A jadeite with grade 5 12 can be seen.

In the past, when ordinary consumers bought jadeite, they only knew that it was divided into three grades: A, B and C. A was natural jadeite with the best quality, while B and C were not. But there are several hundred yuan of jade bracelets and several million yuan worth of pendants in the A goods. Why are the prices of the same A goods so different? How should consumers judge the quality of jadeite?

"The new standard solves the blind spot of consumers' perception of the value of A-goods jadeite. Consumers can roughly judge the value and advantages and disadvantages of jadeite according to its grade. "Deng Kun said that the quality grade of jadeite (A-goods) jewelry was divided into 1 1,000 in the new standard. Only products with a comprehensive score below 25 1 minute can be considered as qualified products. Those above 25 1 minute can be divided into top grades, treasures, fine products and excellent products according to their scores, among which those with more than 700 points can be rated as top grades, and each product is divided into three grades. Finally. " This solves the problem that traditional evaluation only relies on personal experience, or only a single index evaluation does not have the overall evaluation result of jewelry, and realizes a major breakthrough in the field of jade evaluation. "

The new standard specifies the requirements of environment and personnel for jadeite evaluation, the evaluation of jadeite color, transparency and texture inhomogeneity, and the overall requirements of jadeite process evaluation, material application and processing technology design, jadeite quality (including quality unit and weight) and jadeite evaluation certificate.

Can identify jadeites of various colors.

"Colorless, can you put it in the top grade? Colorless is positive color, so how to judge the value of ice seeds ... "At yesterday's expert review meeting, experts, scholars, technicians and entrepreneurs from Yunnan Jewelry Industry Association, Provincial Jewelry Quality Inspection Institute, Southwest Geological Nonferrous Exploration Bureau, Kunbaida, Colorful Yunnan and Cuixi Jewelry launched a fierce debate around the new standard. After careful consideration, they finally reached a unified opinion and released the new standard.

In this regard, Zhang Weihe, honorary vice chairman and appraiser of Yunnan Jewelry Association, said that jade grading is an important prerequisite for regulating the jade market. However, due to the diversity of jadeite color, variety and sample price, jadeite grading has always been a difficult problem in the industry. Before the introduction of the new standard, there was also a grading standard for jadeite, but it was only limited to solving the distinction between A and B goods, or just a single index evaluation of jadeite, without a comprehensive evaluation of workmanship and cultural implications. The new standards issued by Yunnan province make up for these shortcomings.

Zhang Weihe said that the new standard introduces the concept of weight and uses data to evaluate the value of jadeite, which is objective and operable and is a great innovation. At the same time, the new standard introduces and popularizes the vague concept of "species" existing among the people, and it is more authoritative to evaluate the internal structure of jadeite with instruments that can only be identified by naked eyes? .

In addition, the new standard brings the cultural meaning of jadeite into comprehensive evaluation, and also changes the concept that only green jadeite is high-grade jadeite, including the identification of jadeite in all colors. This is also the first in China, which is of great significance to promote Yunnan Province to take the lead in realizing the standardization, standardization and internationalization of the jade industry.

Looking forward to reshaping "Jade Out of Yunnan"

Because jadeite is a commodity with scarce resources, its sales volume has not been affected by the financial crisis. On the contrary, many investors turned their attention to the collection of jadeite. Relevant persons in charge of Qicai Yunnan and Cuixi Jewelry all said that during the 11th period of this year, the sales volume of jewelry and jade reached a record high, with a year-on-year increase of 20%-30%.

"At present, there are more than 500,000 large and small jewelry enterprises, processing households and business households 1 000 in Yunnan, with nearly 500,000 employees. The jewelry and jade industry featuring jadeite has formed a considerable scale. " Deng Kun said that Yunnan jewelry and jade industry has unique advantages in location and resources, history and culture, market and brand, and the jewelry and jade market has great development potential.

"There is still a certain gap between the overall market sales of Yunnan jadeite and Guangdong." According to the analysis of the insiders, due to the poor entry channel at the land port of jadeite wool in our province, the supply of raw materials is insufficient, and the status of jadeite raw materials center is lost, resulting in a large number of brain drain, unclear industrial data, unclear family background and unclear development ideas. In addition, the support measures are too conservative, and the policy innovation lags behind. Yunnan jewelry and jade industry is squeezed by other provinces' markets, and the industry confidence is insufficient.

Pagan, where Myanmar jade raw materials are concentrated, is more than 800 kilometers away from Mandalay, Myanmar jade sales and processing center, while Yunnan is only more than 500 kilometers away from Pagan. However, there is no large-scale decent processing center in Yunnan. Myanmar's raw materials are processed and sold in Guangdong, and it has no geographical advantage for Yunnan after entering China. Xiao Wen, general manager of Tracy Jewelry, said with some helplessness that to make Yunnan's jewelry and jade industry bigger and stronger, we must first introduce talents and attach importance to processing links.

The transaction price and frequency are clear at a glance.

Yesterday, Yunnan Jewelry and Jade Quality Supervision and Inspection Institute issued the first batch of "quality inspection certificates for high-grade natural jade ornaments" (hereinafter referred to as "high-grade certificates").

The winner of the "Top Grade One" certificate is Yang li Ping's colorful "peerless elegance" jewelry in CCTV advertisements, worth hundreds of millions of yuan. The reporter saw that the high-grade certificate assessed according to the new standard not only assessed the grade of the product, but also explained the variety, water color, workmanship and defects of the jade in detail, and also explained the meaning of "peerless elegance" in detail, and attached a "transaction record" to the certificate, so that buyers can clearly understand the price and transaction times of the purchased products in the future.

At present, China is one of the few countries in the world where the annual jewelry consumption exceeds 654.38+000 billion US dollars, and it is the most important jewelry consumption market in the world. However, it is difficult for consumers to judge whether the jadeite bought at 6,543,800 yuan and the jadeite bought at 300,000 yuan are the same grade. With the high-grade certificate, consumers can see at a glance the five important evaluation items of jade, such as variety, moisture, color, workmanship and defects, and truly distinguish high-grade jade from qualified jade products.
