For a long time, there is no grading evaluation system as simple and easy to operate as diamond "4C" in the jade market. "Jade is priceless" brings consumers not only the mystery of jade, but also helplessness and confusion. In this environment, Zhao Yi Xintiandi Co., Ltd. has created the classic egg noodle modeling of colorless and transparent jadeite (known as glass jadeite in the industry) through repeated practice, which embodies the brilliant beauty of glass jadeite to the greatest extent. After that, the Classification of Transparent Jade (Colorless), which was declared by Zhao Yi Company and jointly formulated with the National Center for Quality Supervision and Inspection of Jewelry and Jade, was approved by the Ministry of Land and Resources in August 2009 and officially announced on 20 12.
