Prior to joining GIA as Director of Research in 2005, Ken served as the Laboratory Director at the American Gem Trade Association (AGTA) Gemological Testing Centre in New York; Director of the Asian Institute of Gemological Sciences (AIGS) in Bangkok; and Chief Executive and Director of Laboratory Services at the Gemological Association and Gem Testing Laboratory of Great Britain (GAGTL) in London. He was appointed Managing Director of GIA Southeast Asia in 2008. He retired in 2015 but in 2016 became a consultant to Mumtalakat (the Sovereign Wealth Fund for Bahrain) focusing on expanding the capabilities of the Gem & Pearl Testing Laboratory of Bahrain which he had helped set up 25 years previously.
Over his career he assisted in the setting up of pearl and gem laboratories in Bahrain, Qatar and Dubai and consulted for the Bombay Pearl Association to improve their testing facilities. He has been involved in many projects, not the least of which was the examination of the British Crown Jewels; here he detailed every stone in such notable items as the Imperial State Crown, St. Edwards Crown, the Queen Mothers Crown, and the Sceptres. He detailed and graded both the Cullinan I and II diamonds and the Koh-I-Noor, three diamonds that represent the largest and most historically significant.
A writer on gemological and trade issues, Ken’s articles have appeared in numerous industry publications including The Journal of Gemmology (UK) and Gems and Gemology (USA). He also co-authored the books The Crown Jewels and The Pearl and the Dragon.
Ken has lectured to gemmologists and traders in many countries including Australia, Bahrain, Brazil, Canada, China, Colombia, France, Hong Kong, India, Israel, Italy, Japan, Korea, Singapore, Thailand, Sri Lanka, UAE, UK and the USA.
In addition to his passion for diamonds, rubies and sapphires, Ken also has a strong interest in pearls and has visited and studied in most of the world’s major pearl producing countries.

David Callaghan joined the West End firm of jewellers, Hancocks, as an apprentice in 1955 and continued his career there until his retirement in 1997. Appointed to the Board of Directors in 1964 he eventually became the senior Director.
Hancocks, uniquely, are the sole suppliers of the Victoria Cross since the inception of the award in 1856 and David has made a particular study of this unique award for over 40 years.
David became a Freeman of the City of London in 1964; was made a Freeman of the Worshipful Company of Goldsmiths in 1975 and was “clothed with the Livery” of the Company in 1983.
He is the current President of the Society of Jewellery Historians.
John Harris entered the Jewellery trade in Glasgow in 1948 and after completing his apprenticeship as a Heraldic Silver Engraver went on to study gemmology and obtain his FGA in 1956. The following year he became self employed and moved to Carlisle where the family business still operates managed by his son.
During his many years as a Gem-A tutor John lectured and ran workshops in which he specialised in the practical use of the spectroscope. Early attempts at photographing gemstone spectra through the spectroscope began about 1980 using 35mm.emulsion film and advanced with digital imaging around the year 2000 at which time his Spectra Database was launched on the internet.
Research in this field led to him being awarded “The R. Keith Mitchell Award” by the Gem-A in 2009 during which year he also became an Honorary Life Member
John is also responsible for the excellent website on Spectroscopy,

Alan Hart started his career at the Natural History Museum in 1981 as Assistant Minerals Scientific Officer, progressing to the position of Principal Curator of Gems and Minerals and Head of Earth Sciences collections. Alan led the Earth Sciences Collections team of 25 people, and is Chair of the Museum’s Collections Committee and various science executive boards providing strategic and operational goals to improve standards, best practices and operational efficiencies whilst delivering major projects that improve care and access to the museum’s collections of some 80 million items.
More recently he was responsible for writing the initial digitisation strategy for the Museum’s collections. As a lifelong self-confessed passionate mineralogist and gemmologist who formally graduated into the gem world five years ago by obtaining FGA and DGA, he has developed the collections and provided access to them for many aspects of research and education.
Alan is very well known in the Museums, private collector sectors and gemmological industries environment and has developed many collaborations in terms of opportunities for collections development at the Museum. From first initiating a targeted development strategy for the collections some years ago, he has been instrumental in facilitating the acquisition of many major collections items, from beautifully crystallised gem minerals such as a magnificent group of emeralds from Kagem mine, Zambia, to the world’s most completely preserved Stegosaurus, all of which are now highlights of the Museum collections. Alongside this he has developed and curated three major exhibitions: ‘Earths Treasury’, ‘Diamonds’ and ‘The Vault’, and undertaken numerous media activities representing geosciences.
His personal research is wide ranging within the mineral and gem fields, but he currently focuses on the cutting of famous Mogul diamonds, also being able to link people to collections and collections material to facilitate their research alongside other wide ranging related activities. The Museum has a long history of association with Gem-A where Alan was appointed as a Trustee two years ago and, this year, became Gem-A’s new CEO.

Andrew Fellows FGA DGA has had a varied career within the world of gemmology. Starting as a production planner in 1992, within the UK's largest jewellery manufacturer, Gallery Jewellers, based in Birmingham's Jewellery Quarter, he quickly developed an interest in gemstones that saw him start on a succession of gemmological courses. Over a decade later, Andrew moved from a manufacturing environment to the retail sector, taking a role as in-house gemmologist and diamond grader for J.E.Marlow & Sons. During this time, Andrew started teaching as a correspondence tutor for the Gem-A, first on a part-time basis, then in 2011, taking on a full-time role as the IT Implementation Manager in Gem-A's London headquarters. Overseeing and developing the online aspect of the Foundation, Diploma and Gem Diamond courses, Andrew was also an evening tutor, covering the Diamond and Foundation years. Whilst there, he also travelled extensively to trade shows, promoting Gem-A courses, and Gem Instruments, and providing talks, seminars and workshops.
In 2016 Andrew left Gem-A to accept a lecturing position at Birmingham City university, on the BSc in Gemmology and Jewellery Studies course, where he is now expanding the knowledge of the next generation of gemmologists.
Outside of work, Andrew has also authored a series of articles on gemstones, in the "Jeweller" magazine, and has written numerous articles and reviews for "Gems and Jewellery", a publication on which he also served as a member of the Advisory Board. Working with the Smithsonian, he also acted as consultant for the recent Dorling-Kindersley "Gem" and "Jewel" books, published in October 2016.
