"I wanted to thank you again for the outstanding support you gave me during the last two weeks.
The information I gained from reading your book, and from corresponding with you via e-mail, gave me a tremendous
advantage in making my diamond purchase. I was able to identify honest diamond dealers from dishonest ones,
select a diamond of outstanding quality, and negotiate a fair price. As a result of your recommendation,
I was also able to locate a local gemologist who could evaluate and appraise my diamond. I cannot imagine
making a purchase on this magnitude without the information contained in the IGS Diamond Buyer's Guide. I
recommend your services unequivocally to anyone preparing to make the same purchase.
