Gemmological Institute of India is a gemmology training school in Mumbai, India.
The Gemological Institute of India (GII) is a non-profit school in Mumbai that conducts courses on gemmology. It was founded in April 1971 by the Gem and Jewellery Exporters' Association, Bombay. It offers diplomas for gemmology and diamond grading, and courses on jewellery design, pearls and bead stringing, diamond casting, and craftsman training. The school courses enable students to take the certification of Fellow of Gemmological Association (FGA) examination of the United Kingdom.
It publishes a quarterly publication called Indian Gemmologist. The GII is recognized by CIBJO which is an international confederation of jewellery trading industry that harmonizes standards set by gem testing laboratories.
The GII established India's first Gem Testing Laboratory in 1971, and started India's first Gemmology course in 1974. It started its Research and Development Laboratory in the field of gem stones in 1976, and its first Diamond Assorting and Grading Course in 1978. It started the first correspondence course in Gemmology in India in 1983, Jewellery Casting and Jewellery Designing courses in 1995.
The Gem Testing Laboratory was recognized by the International apex organization of Gem and Jewellery Trade, CIBJO. With increasing consumer awareness, the jewellery industry worldwide began to issue certifications to attest the quality of gem and diamond products. The GII started diamond certification in India in 2000. . [1]
In November 2004, during the 25th convocation, it was announced [2] that the Gem and Jewellery Export Promotion Council (GJEPC), Diamond Exporters' Association Ltd, Bharat Diamond Bourse and Gem and Jewellery Exporters' Association together with the Gemmological Institute of India will provide funds to set up a research centre in Mumbai, to carry out research and development activities especially for synthetic diamond and high pressure high temperature (HPHT) treated diamonds. The board was expanded to include eleven trustees, six from GJEPC, three from Gem and Jewellery Exporters' Association, one from Bharat Diamond Bourse and one from Diamond Exporters' Association Ltd.
In 2005, it was estimated that 5000 people have been trained in gemmology by GII since its inception. In October 2005, The GII acquired 4,500 square feet (420 m2) of premises at Sukh Sagar Building at the Opera House to expand its diamond grading laboratory Services. The new facility is called the National Research Centre. [3] In 2005, the department of scientific and industrial research of the central government of India, recognized the R&D Laboratory as a Scientific and Industrial Research Organization (SIRO).
In 2006, the GII tied up with Panjab University, Chandigarh as a research center for Ph.D. Studies in the field of gemstones and diamonds.
An issue the world's jewellery traders face is that synthetic diamonds, which are cheaper and now very widespread, can be used to defraud consumers of natural diamonds. As synthetic diamond technology becomes more easily accessible it is necessary for consumers, customs, importers, exporters, and government to be sure of the grade and quality of the diamond or gemstone. Synthetic diamonds may be produced by high-pressure, high-temperature (HTPT) method or chemical vapor deposition (CVD) method, which leave their signatures in the composition of the diamond. Research includes investigating techniques to look for these differences and distinguish natural gem stones from artificially produced ones.
Emerald is a gemstone and a variety of the mineral beryl (Be3Al2(SiO3)6) colored green by trace amounts of chromium and sometimes vanadium. Beryl has a hardness of 7.5–8 on the Mohs scale. Most emeralds are highly included, so their toughness (resistance to breakage) is classified as generally poor. Emerald is a cyclosilicate.
A gemstone is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks and occasionally organic materials that are not minerals are also used for jewelry and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity is another characteristic that lends value to a gemstone.
Gemology or gemmology is the science dealing with natural and artificial gemstone materials. It is considered a geoscience and a branch of mineralogy. Some jewelers are academically trained gemologists and are qualified to identify and evaluate gems.

The Gemological Institute of America (GIA) is a nonprofit institute dedicated to research and education in the field of gemology and the jewelry arts and based in Carlsbad, California. Founded in 1931, GIA's mission is to protect all buyers and sellers of gemstones by setting and maintaining the standards used to evaluate gemstone quality. The institute does so through research, gem identification and diamond grading services and a variety of educational programs. Through its world-renowned library and subject experts, GIA acts as a resource of gem and jewelry information for the trade, the public and worldwide media outlets.

The World Federation of Diamond Bourses, founded in 1947, was created to provide bourses trading in rough and polished diamonds and precious stones with a common set of trading practices. It is composed of 30 member diamond bourses. Their headquarters are in Antwerp. Members of The World Federation of Diamond Bourses (WFDB) act as a medium for wholesale diamond exchange, trading both polished and rough diamonds. The WFDB consists of independent diamond bourses in major centers of the diamond trade such as Tel Aviv, Antwerp, Mumbai, Johannesburg, London and New York and other cities across the USA, Europe and Asia. The WFDB provides a legal framework and convenes to enact regulations for its members. The following is a list of the 30 bourses.

The Swiss Gemmological Institute SSEF is a gemmology laboratory located in Basel, Switzerland. It is a part of the Schweizerische Stiftung für Edelstein Forschung. It was founded on an independent basis, by trade organisations, in 1974. George Bosshart, mineralogist and GG was the first director after the laboratory's opening in Zürich. Diamond grading was the major task and colour stones were tested rather exceptionally. In 1980 Bosshart hired Dr. Henry A. Hänni, Mineralogist and FGA. In 1994 Hänni moved the laboratory to Basel. He has been teaching gemmology at Basel university, and the close link to the university proved to be very enriching for both parts, academic and laboratory work. Hänni became professor of gemmology at Basel University, also a reward for his years of steady research and supply of publications. Prof. H.A. Hänni retired in 2009 and Dr. Michael Krzemnicki took over his position as a director. Dr. Krzemnicki has been working for SSEF since 1999. SSEF has since long been offering its independent services to the global gemstone and jewellery trade. The mandate of the SSEF is to analyse precious stones and jewellery; issuing test reports for coloured gemstones, diamonds and pearls. Its forte lies in the detection of gemstone authenticity, origin, and gem treatments on a scientific and reproducible basis. It offers expert independent advice to a wide gemmological clientele including gem dealers, jewellers, auction houses and private customers in many countries. Gemmological training courses from basic to highly specialised are a further contribution to an international scholarship, ensuring a high level of gemmological knowledge and skills in the trade.
