瑞士宝石研究院GIS

瑞士宝石研究院，简称”GIS”，属于瑞士联邦材料测试与开发研究所，主要分析天然宝石化学成分、物理特性和自然成因。

瑞士宝石研究院(Gem Research Institute of Swiss )，简称”GIS”，最早成立于80年代的瑞士，是瑞士联邦材料测试与开发研究所（EMPA；Eidgenössische Materialprüfungs-und Forschungsanstalt）的附属机构，通过分析天然宝石的化学成分、物理特性和自然成因，结合最先进的宝石培育技术，在宝石及材料工艺学Gemology and Materials Technology）领域取得了令人瞩目的成绩。

Gem Research Institute of Switzerland (GIS for short), first established in Switzerland in the 1980s, is a subsidiary of the Swiss Federal Institute for material testing and development (EMPA; Eidgenössische Materialprüfunds-und Forschungsanstalt). By analyzing the chemical composition, physical characteristics and natural causes of natural gemstones, combined with the most advanced gem cultivation technology, GIS has made remarkable achievements in the field of Gemology and Materials Technology.

瑞士宝石研究院的主要研究方向包括宝石地质学、结晶学与矿物学、岩石学、宝石学基础、珠宝玉石鉴定、宝石合成及优化处理、珠宝首饰评估概论、钻石鉴定与分级实验、宝石测试技术等。

The main research fields of Swiss gem Research Institute include gem geology, crystallography and mineralogy, petrology, Fundamentals of gemology, jewelry and jade identification, gem synthesis and optimization, introduction to jewelry evaluation, diamond identification and grading experiment, gem testing technology, etc.

瑞士宝石研究院十分重视国际间科研合作，自成立起即与国际主流的珠宝机构建立和保持密切的教学、研究合作与交流。目前已经与英国的伯明翰珠宝学院(BIAD)、法国的英赛克高等商学院(INSEEC)、国家宝石学院(ING)、美国宝石学院(GIA)等世界著名学府的珠宝首饰教育机构建立了科技合作和学术交流。

Swiss gem research institute attaches great importance to international scientific research cooperation. Since its establishment, it has established and maintained close teaching and research cooperation and exchanges with international mainstream jewelry institutions. At present, it has established scientific and technological cooperation and academic exchanges with jewelry education institutions of world-famous universities such as Birmingham Jewelry Academy (BIAD) in the UK, Insec Higher Business School (INSEEC) in France, National Gem Institute (ING) , American Gem Institute (GIA) in the United States and so on.

从2000年开始，GIS开始联合世界上重要的宝石学机构，通过一定的技术与工艺流程制造与天然宝石外观、化学成分和晶体结构完全相同的培育宝石；并通过微量元素分析，激光扫描技术，最新的谱学技术和庞大的数据库，成功地对天然以及培育宝石进行了精准的颜色、切工分级。在应用宝石学上的这一成就，至今没有被学术界的同行超越。这使得GIS出具的宝石颜色，切工分级证书，在国际珠宝市场具有了权威的地位。

Since 2000, GIS has begun to cooperate with important gemological institutions in the world to manufacture cultivated gemstones with the same appearance, chemical composition and crystal structure as natural gemstones through certain technologies and processes; Through trace element analysis, laser scanning technology, the latest spectroscopy technology and a huge database, we have successfully carried out accurate color and cutting classification of natural and cultivated gemstones. This achievement in applied gemology has not been surpassed by peers in the academic community. This makes the gem color and cutting classification certificate issued by GIS have an authoritative position in the international jewelry market.

目前他们对社会提供的证书服务包括：
