Hi,
As a non-gemologist, I found this Online Handbook called "Handbook for the Gem Buyer - Preface and Table of Content

This is the Table of Contents [below]. 
Each 'subject label' is 'clickable' [at the Ganoksin Websitehttp://www.ganoksin.com/borisat/nenam/contents.htm and takes you to excellent info for someone who wants to know 'more', but doesn't want to get bogged down in too much heavy info.

Hmmm.....you're right.  Guess I should have looked at the link code before I posted it.  Duh!!!  hide Thanks for adding it.  I just fixed my posting as well. ura
It's not 'monumental' but for newbies in the world of gemstones, like myself, it's 'short and sweet'. yes

I have found it always works better, if you cut and paste the link on a line of it's own. Then, I check that the link works in preview mode before I submit it to the forum.

I'm wondering when this was written? There is some glaringly obsolete information in this (esp. in the treatments section, where many gems that are now known to be subject to heavy treatment are described as "not enhanced by present technology" and some of the treatment methods described have been superseded by other, harder to detect treatments).

The Ganoksin website says "1999" - I guess I'm showing my age, but somehow that doesn't seem so long ago.  bricks

Ya know....the lapidary guru's on this website should collaborate on an updated version of this handbook and send it to Ganoksin to post .   
What an awesome handbook THAT would be.   

Some people have tons of knowledge about 'specific stones' but maybe no one has equal knowledge about ALL the stones.
Each guru member could just take on the stones they know.  Keeping it as a "Handbook for Gem Buyers" [updated] [i.e., not intended for gemologists....but for ordinary mortals. 
Each guru or multi-gurus could be credited for the stones they collaborated on.

Would that be cool or what!!!!    thinking13 omg   toocool2

It doesn't seem that long ago to me either.  But 15 years is an eternity when it comes to gem treatments.  The "bad guys" always manage to be a few (or more) years ahead of the "good guys."  I'm certain there are treatments out there that haven't yet been detected.  Part of the problem is research money goes to high-end gems like diamonds, emeralds, rubies, sapphires etc. because that's where the big money is.  The "fairly" recent (showing my age too) foofaraw over "red andesine" is proof of that.  It took years for the gem labs to generate enough interest to prove that nearly all of the red "African" and "Tibetan" feldspars being hawked on the TV gem shows were phonies cooked up in Chinese ovens.  Andesine is a low-end gem in terms of price, and even though thousands of consumers were being defrauded, they didn't have the clout to interest the elitist gem labs.

All the more reason to provide an updated handbook.

You don't have to be a professor or anything to enter things into the Ganoksin website.  Just knowledgeable about something related to the Jewelry or Lapidary or related world.   I'd TOTALLY be involved, except I really don't know anything to contribute.  This forum is loaded with knowledgeable people.
It just take the will to document it and post/submit it. party2

Writers wouldn't even have to start from scratch.  Just review the gemstones in the existing Handbook, and submit 'updated information' on treatments or whatever that have been seen since the Handbook came out.   Photos of what the treated stones look like, and how to notice the treatments, would help too.
