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treatment are described as "not enhanced by present technology" and some of the treatment methods described have been superseded by other, harder to detect treatments).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.
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!!!!
