Barbara W. Smigel, PhD.
Graduate Gemologist, GIA
Artistic Colored Stones

Barbara developed her interest in gems rather later in life than many (after age 40). The earlier part of her life having been devoted to researcher and teaching in biological science and to raising a family. From an initial interest in collecting rare gems, the progression was to gemology student (culminating in a Graduate Gemologist diploma from GIA), to a becoming a facetor and jewelry designer, and ultimately reaching its present form as gem dealer and gemology instructor. Her website, www.acstones.com, debuted on the internet in 1997 and has evolved to become one of the preferred web destinations for the gem lover.

John I. Koivula

John Ilmarii Koivula has been studying and photographing the microworld of gemstones since 1961. As an extension of his inclusion research and microscopy he has developed several useful illumination techniques applicable to gemology. He introduced fiber optic illumination to gemology and discovered many of the micro-characteristics now routinely used in the separation of treated stones from natural gems, such as internal diffusion in proving treatment, chromophore cannibalization and the usefulness of intact carbon dioxide and other fluid inclusions in proving natural color.

Koivula has authored or co-authored more than 800 articles and notes on gemstone inclusions, microscopy and related topics for a wide variety of professional and trade publications.

He is a contributor to several books including the American Geological Institute's Glossary of Geology, the fifth edition of Robert Webster's Gems, the Gemological Institute of America's (GIA) "Diamond Dictionary," and two forthcoming reference volumes Geologica: A Study of Crustal Landforms and On Gemstones: Gemological and Analytical Studies of Ancient Intaglios and Cameos. Mr. Koivula and Dr. Eduard Gübelin are co-authors of the major gemological reference work, Photoatlas of Inclusions in Gemstones. In addition, John Koivula's book, The MicroWorld of Diamonds, covers natural diamonds, synthetics, simulants, and enhancements. Together with Dr. Gübelin, Mr. Koivula has now completed Photoatlas of Inclusions in Gemstones, Volume 2, which focuses on the identifying characteristics of natural gems, recent synthetics and treated gem materials. Photoatlas, Volume 2 was released in January 2006. Photoatlas of Inclusions in Gemstones, Volume 3, which will conclude the series, was released in late 2008. It includes chapters dedicated to diamonds, emeralds, rubies, and sapphires. In addition, there are 21 chapters on rare stones.

Koivula was instrumental in the development of the "MacGyver" television series for ABC, working as scientific and technical advisor on the show during its seven year run. Before joining the Gemological Institute of America in 1976, he worked in the mining industry performing mineral exploration for Cominco American. He also worked in the retail jewelry industry for several years.

Currently, John Koivula is Chief Gemologist of the Gemological Institute of America, in Carlsbad, California.

Olivier Louy, M.Sc., A.G.

Olivier is running from 2009 the "Laboratorio Gemologico Suizomex" in Mexico City.
Like many gemologists, he likes the world inside the natural or synthetic gems: "It is always a challenge to catch those inclusions but it is cool to share them as  they are so important in gemology especially for the students".

Starting his professional life in 1979 with a Swiss diploma in watch making he was working for  Piaget, Baume & Mercier and other famous jewelry watch makers in Geneva. From then, he has fallen in love with beautiful mechanics and high quality jewelry.
 
Now, he's holding a Master of Science in Earth Science from Montreal  University and a Diploma of Accredited Gemologist with Highest Honors from the Asian Institute of Gemological Science.
On the side, Olivier is dealing with gemstones and pearls from 2000 and regularly traveling to Bangkok and Chanthaburi for business.

Wilford Bickel

Wilford has a degree in Textile Chemistry from the school of Engineering at Auburn University.  He is an accomplished and award winner in mixed media art shows with his wood turning.  A few years back he had to take early retirement due to health reasons and started spending more time with his wood turning hobby.  It was during this time that he started developing a line of jewelry and was looking for something to make his jewelry different and special.  With his chemistry background he soon developed an interest in gemstones for this use and over the last few years he has developed a real love for the gemstones as he has for exotic woods.  With his chemistry background the use of the gemology identification instruments and the use of digital microscopy closely relates to his 25 years as Lab Director for a specialty chemical manufacturer.

A Short History of Gemology Tools

 In July 1993 I went on the road doing independent appraisals working at diamond remount shows for various jewelry stores. Portable gemology equipment is great but it is heavy. Being the type of person that wants to make sure I get everything right I also lugged around 3 or 4 gemology reference books. I thought someone should consolidate all that information and put it on a computer. I looked around for such a program and found none. So I sat down and started programming the first version of Gemology Tools. I used the first version of Basic which came with MS-DOS. In 1994 I upgraded to a more robust version of Basic and the program started to take shape. I needed a more versatile programming language and tried Turbo C. I found C pretty tough and kept asking my brother, Pat, for assistance. Since programming was his hobby he soon took over the programming duties. I handle all gemological issues and content

First Windows Version: We came out with our first Windows version on February 21, 1995. At the time we sold both DOS and Windows versions with DOS outselling Windows 4 to 1 in 1995. Gradually the Windows version took over the lead and finally the DOS version was phased out in about 1997. Amazingly, we sold GT on one floppy disk until 2003. In 2003 we started burning GT to CD's. This allowed us to add photographs and greatly expand the program.
