Hi Folks…
I have some experience with Dr. Hanneman…
Basically…his premise is that instead of spending thousands of
dollars on gemological equipment…there is another way, in a lot of
cases…
Example…for all of those who cannot afford a darkfield system
for loupe viewing…he has an amazing alternative…
I will second the Doctor’s advice as to “Guide to Affordale Gemology
”…
Dr. Hanneman has no email address that I am aware of… So…you
have to communicate with him via snail mail…
If you are at all interested in another way to come at things
gemological… Then contact him…(as the Doc stated)…
Hanneman
Gemological Instruments
P.O. Box 1944, Granbury, TX 76048
Don’t use what you may find on the Internet…because a lot of info
will show him someplace else…but he is in Granbury…
I got his book first… And then ordered a number of things from
him…
Due to a miscalucation…my check to him was $6 short…
He sent the items anyway, noting the shortage…I sent him another
check…
The other thing I’ll mention…
Doc H…refers a lot to Schumann’s “Gemstones of the World
”…
Because of it’s tables of gemological …
I understand that there’s a new version of this book coming out late
this year…
Hanneman uses it because of its tables… I’ve seen a couple of the
on-line education folks referring to it also… Schumann is an
incredible mine for data, or, you can use it as an eyeball kind of
thing…
This is a book no one into stones should be without…
I have the current one…(until the end of the year, at any
rate)…
It is a hardcover…and beat up from use again and again and
again… List price is $24.95… Probably better price on Amazon (I
paid $16 back when)…
If you are not one of those fortunate enough to be able to do a GIA
course, and get their texts…
Or…would want a great reference to the World of Gemstones in
general… Smaller hardcover…lots of pictures, and as I
mentioned…gemological …stats, if you would…
Some of the newer stuff…moissanite, for example…has not found
it’s way into the edition available currently…I am hoping the
newest edition will remedy that… I have notes and additions
scribbled throughout mine…
Uhhhh…no ref to green amethyst, but prasiolite is in there…
It will be the best $25 you have ever spent…
Even if it only mentions fire agate, but shows no pictures of it…
I do not know if the new book will be hardcover for sure…But it’s
the only way I myself would have it…
Softcover would die under the use and abuse…
