I was working for J. & S.S. DeYoung's in Boston as their gemologist from 1974 - 1980. I helped make the single biggest sale in the history of this firm to the King of Saudi Arabia, by providing an extensive provenance from my personal library on gems and jewelry with some 65 pages of documentation of ALL references in the English language. Both the Nassak Diamond 43.38 carats with GIA NY Certificate #23998 “D” “internally Flawless” bought in mid 1976 & a unique Gem Burmese Ruby of 35.22 carats bought in 1978 with GIA NY Certificate #141093 (soon re-polished to 34.25 carats) were extensively documented with all records coming from my personal library at my home. These leather bound documents were done by me without any request from DeYoungs, as an effort from their new young 24 years old gemologist to show them what I was capable of producing. As the firm’s European salesman explained twice after this sale was completed, to all those at DeYoung’s, “the King had seen the stones before from our business partner and was not impressed. When shown both gems on the second showing he was also given the 2 leather bound volumes of extensive research on them. He read them for half an hour and then agreed to purchase both these fine gems”. I not only did not receive any commission for my critical part in this record making sale but not so much as a thanks or that was a good job. See the article by David Federman, editor of “Modern Jeweler” on this sale and other interesting background, reproduced below. As Richard T. Liddicoat says in the foreword of “MODERN JEWELER'S GEM PROFILE, THE FIRST 60”, 1988, by David Federman, "No one investigates a subject in more depth than Mr. Federman and no one writes with greater clarity on the matters that he studies so assiduously." (see, GEMS & GEMOLOGY, Fall 1988, Book Reviews, p. 191 -192 and GEMS & GEMOLOGY, Spring 2002, “Richard T. Liddicoat, The Ultimate Gemologist”, By Dona M. Dirlam, pp. 2 - 13). For the 24 years since this article was first widely circulated there has not been one serious objection as to accuracy of any of the statements related therein. I did learn much from this significant experience about the importance of good research and establishing an extensive provenance on historic gems and jewels. Bob Crowningshield, Vice President of GIA & head of the GIA labs in NYC, called me in early 1980 as a last resort, concerning the famous “The Crown of the Andes”. I happily supplied him with not only extensive documentation but also the current owner’s name (see documents below). Mary Murphy, head gemologist at Christies in NYC called me about the same time, about a piece they had for auction, “The Green Cross” from the Henry Phillip Hope Collection (then owner of the famous “Hope Diamond” that is now in the Smithsonian). I gladly sent Mary the pictures and the original description of this unique green gem. I had taken these pictures from the personal copy of Mr. Henry Thomas Hope’s (signed by him), “Henry Phillip Hope Catalogue” that was published in London in 1838 and this was now in my library (see documents below). Christies used all this in their jewelry sale catalog for Geneva 1980, and I was happy to help them on this matter as well as several other instances.

Modern Jeweler by David Federman, Editor Jan 1985

I had to make private sales to support my gem book collecting habit. I managed to get a library when these books were still cheap and it included ALL the publications and books published in English that John Sinkankas, famous gemstone writer and gem book collector, had and more on gems and jewelry. I stayed at John’s house in San Diego several times and we were close friends since 1968. I was always proud when I visited John Sinkankas at his home in latter years to see my ”Gill’s Index” on a small shelf of books at his desk, where he did all his writing next to his 14,000 book library. The John Sinkankas Library was purchased by the GIA in 1987 and now makes up the core of the entire GIA’s world class library.

I did not know how to type so when I did my index I hand wrote each entry on 5 by 8 inch cards about 4 feet thick of them. Each time I read a new sentence I had to look up the right card to make the annotated entry. After 9 years of work I completed a 420 page book with over 14,000 entries. So you can look up France and find that a rough diamond was found there or what gems were found in Antarctica or California or Nigeria or Ghana or Florida or in the oceans or anywhere including from outer space. You can find all the references ever in English from the first book done by Thomas Nicols on gems in 1652 until 2008, near 350 years of all the publication in English on gems along with more than 18 journals on gems and minerals. I went through each sentence of each publication and all was put in this handwritten annotated index. I did my work in my small apartment with my wife typing out the final draft (an 18 month job). This was only the second book ever published by the GIA that was not done by a member of its own staff. See G & G, Fall 1980 p. 367 - 368 “Where Have All Our Answers Gone” and on p. 368 - 369 “Gill’s Index” reviewed by Dr. Edward Gubelin. Gubelin says “The idea and concept of Gill’s Index should be taken up by other scientific branches of knowledge. After all, the motto for the expert stands: Not the not-knowing is shameful, but the not-knowing where you could look it up”. Dr. Gubelin did seven different very positive reviews of “Gill’s Index” in four languages and called it “a marvelous index”. Dr. Wendell E. Wilson, editor of The Mineralogical Record in his own full review of “Gill’s Index” agrees with Gubelin by saying “Why has such a comprehensive index not been produced for other important areas of study”, and Wilson continues “Gill’s Index represents an enormous labor of love requiring years of work, significant funds, and a degree of motivation beyond most authors”. G & G Summer 1979 p. 190 “GIA Publishes An Essential Gem Book, GILL’S INDEX, this will be updated every few years” and Richard Liddicoat also proclaimed in the G & G “The GIA is proud to announce the publication of “Gill’s Index” as part of a continued effort to keep the jewelry and gem industry informed”. I had the opportunity to talk to Dick Liddicoat at his home via phone three months before his passing and he was most enthusiastic about the idea of putting the “Gill’s Index” on the web as “Gill's Historical Index Online” where interested people, including authors, could continually update it. Winter G & G 1979-1980 p. 250 top right reads “GIA’s latest Reference book”, “information is easy to find with Gill’s Index” (see documents below).
