I have received an old book that I ordered from England: " Gem Testing" ninth edition by BW Anderson, 1979. It is the last version that the author made before he died.
That book was recommanded by monsieur Hanneman. I am really pleased with it. That book seems to be a very good vulgarisation of the science behind gem evaluation. It will take me some weeks to read it.
Wel,l 2 weeks vacation in view. There will be skiing, playing in the snow with the children, watching good family movies, family games and reading that book.
I also found an another book that seems very good. It's goal is to help identify with spectroscope. That one is new and gives color pictures of gem specters: http://www.gembluechart.com/order.html. I think that it can be helpful. I might buy it later.

This is an excellent reference! Well organized and easy to use. I recommend it highly. No $ interest, just a satisfied user.

Hi to everybody! Still I don't have the book Barbra and Alberto recommended, but I think it's very interesting as a consultation book for making a good analysis. I studied gemmology since 1990 on the Italian version of Anderson's "Gem Testing" (in Italian: Gemmologia Pratica), and I felt very well in reading it. If I find (as soon as possible, hopefully!) the "Tables", I will buy and read that book, for sure! Greetings from Italy by Riccardo.
I bring back that old subject to speak about the recommandation of Barbra, well sustained by many of you.
Well, yesterday, I followed the link. I wrote ti the email address to give my address so I can have the global cost( book and shipping).
I have no answer so far. Is it normal? Do you know another place wher I could buy it? The only other place that I have found is Australia! I would prefer somewhere closer to Canada.
You were right again! I have received the answer today. I was answered by one of the author, monsieur Dedeyne. He told me that he will sign the book, as you said.
He also told me that I can write to him in french, so I did. I wrote him that his book has been recommended by you, seconded by others, on this forum.
Of course, the book's price is important. The total cost is almost $170.00 in canadian dollars. But you wrote it was the best!
I find the Anderson book very clear and helpful, for more detail I go to "Gems" by Webster and Read. For spectroscopy my first port of call is "The Spectroscope and Gemmology" by Anderson and Payne. I find this an excellent and wideranging book with sufficient background to make it very interesting and informative. If I have a grumble it is that the spectra are shown in black and white rather than colour. I am toying with the idea of making a transparent overlay in the spectrum colours and the right size to fit over the spectra in the book (easy enough, photograph a spectrum, enlarge it to the right size and then print it on transparent film). I would need two. one for the spectrum as seen in a diffraction spectroscope, one as seen in a prism 'scope. An interesting project for an idle hour. Alan F.
