Crystal medals are a symbol of noble purity and image, often used in government and corporate awards. Applicable to the use of qualifications, awards and important events. The production process has the following steps: cutting, pressing, rough polishing, fine polishing, punching, engraving, sand blasting, viscose, quality inspection, packaging.
“Golden Jade” is the style adopted by the medal makers of the Beijing Olympic Games. It shows the “golden jade” in Chinese traditional culture, which reflects the Chinese people’s praise for the Olympic spirit and the award for athletes. Its design scheme, the creativity is very novel, breaking through the tradition of the single material of any previous Olympic medal design, and incorporating the typical Chinese cultural elements. The medals of the Beijing Olympic Games with the "golden jade" as the creativity evolved from the traditional Chinese jade Shuanglong Puhua. The whole medal is distinguished and elegant, and the Chinese characteristics are rich. It not only embodies the praise of the winner, but also the interpretation of the values of the Chinese nation since the ancient times with the meaning of "Jade" and "German". It is the Chinese civilization and the Olympic spirit in the image of the Beijing Olympic Games. Once again, "the combination of Chinese and Western."
The quality requirements for making jade for secret medals include color, texture, clarity, cracks, stone grain and transparency.
Color is the primary condition for medals with jade. There are two main considerations from the color point of view: First, the color category: Kunlun jade color types are mainly white, white, green. Followed by black, sugar (maroon), green and yellow. According to these color types, it is divided into white jade, white jade, sapphire, ink jade, sugar jade, jasper and topaz. Dong Zhenxin said that white jade, white jade and sapphire are common varieties. The color of the white jade used in the medals is white, not gray, and not yellow. Sapphire is grayish black and green, not too dark. The white jade is a color between white jade and sapphire, grayish green. Second, the degree of uniformity of the color: the color of the jade used in the medal should be uniform, and there should be no different color distributions such as spots, stripes or strips.
The quality of the jade used in the texture medals should be fine, and the particles can not be seen by the naked eye. Only after tens of times of magnification under a polarizing microscope can the mineral crystals be seen. It is made up of countless tiny tremolite-emergency mineral crystals. The particle size is generally between 0.01 mm and 0.1 mm and is interwoven in a fibrous and felt-like shape. This structural feature makes it have the characteristics of high toughness and strong impact resistance. Therefore, it is embedded in the medal and falls from the height to the ground and is not easy to be broken. Dong Zhenxin admits that if the jade particles used are coarse and the minerals are not tightly combined, they are easily broken. Therefore, jade with rough texture cannot be used as a medal.
