Dr. W. Wm. Hanneman is a retired research analytical chemist. Gemology is his hobby. In the mid 1960’s, desirous of learning gemstone identification, he was told he must first take several prerequisite courses, each of which cost more money. Instead, he decided to buy some good books and teach himself.
As a chemist, and since all gems were chemical compounds, Dr. Hanneman recognized gem identification could be considered a "game" of qualitative analysis. Although having millions of dollars of analytical equipment at his disposal at work, he chose to play this game using the most simple and basic equipment possible. In fact, he made his own equipment. Part I of this book tells you how you can make your own instruments.
Along the way, Dr. Hanneman developed and promoted the concept of Confirmative Gemology and his "ultimate weapon", The Jeweler’s Eye. After 25 years, the American gemological establishment has yet to come to understand this instrument. Classified as an iconoclast, Dr. Hanneman has found that the American gemological powers have never had an interest in promoting his concepts. Consequently, a whole generation of American gemological graduates has been spawned who do not know his name. His significant technical papers, however, have found eager acceptance in foreign journals and his instruments have been featured in the classic English gemological books for nearly 20 years. In 1975, Dr. Hanneman introduced the Hodgkinson Method to U.S. gemology. Twenty years later, it has now become the "new rage" of the Graduate Gemology Alumni Groups.
At the 1998 Tucson Gem Show, Dr. Hanneman sought to purchase the latest gem identification textbook from what he considered to be "The Source". He was informed that there was no textbook and their "course material" was the text. Needless to say, to take that course requires an expenditure of several thousand dollars. "So much for the concept of gem identification for the public," he thought. "Apparently, gemological techniques are destined to become ‘guild secrets’ for only the wealthy. That should not be." In true iconoclastic form, Dr. Hanneman concluded that his clothes were just as good as the emperor’s, and he could provide a guide to gemology:
|For those who don’t need a diploma to convince themselves or others they can identify gemstones,|
|For those who believe they might be interested in learning the subject, but don’t want to spend thousands of dollars just to find out,|
|For present students and past graduates who are interested in being exposed to techniques not covered in their courses,|
|For viewing it from a perspective "foreign" to current views|
Within the covers of this book, Dr. Hanneman has presented his guide. And above all, it is affordable.
A must have for anyone seeking an alternative, non-establishment view on gemstone identification, with excellent guidance on how to practice the trade affordably, and even build your own tools for gem identification.
This product typically ships within 1 business day.
A lot of people need a formal "diploma" from a highly respected institution, along with lots of costly equipment. That type of training is highly recommended if you really want to understand gemstones.
If your goal is to simply identify some of the most common gemstones - part of the time - Dr. Hanneman provides an alternative approach using low cost "equipment" that can be carried in small package.
He clearly understands the problems of buying (and selling) gemological equipment in the United States and presents his opinions with feisty panache. RockHunter on Jun 19th 2017

Dr. Hanneman shows interesting and easy ways to understand identifying gemstones
using your eyes and brain without directly using high priced instruments. I go to Dr.
Hanneman's "Affordable Gemology" book before I use my many gemological reference books. Thank you Dr. Hanneman Jeff Dolson on Feb 16th 2017
I've been searching for this book for many years. Finally found it for sale with Mineral Lab, and by random accident at that! I desided to try and ask the reference desk at a library if they could help me think of any way to get my hands on a copy, as I had only located one - and it was not available for interlibrary loan; at the GIA library in CA.
So the librarian desided to Google the title, and POOF! It's available for purchase, lol.
So I place my order with Mineral Lab; a few minutes later, I recieve a confirrational email my order is being processed for shipping. A few minutes after that, another email with the tracking number and that I can expect delivery within the week! VERY PROMPT, FAST SERVICE; I AM SO DELIGHTED! a very happy customer on Jun 22nd 2016
