"Mr. Sheffield's IGS Diamond Buyer's Guide has most definitely served
as my best friend during my search for a diamond engagement ring.  When
I first made the decision to start shopping around I felt somewhat
anxious.  I had no idea that my lack of knowledge would be instantly
remedied and transformed into 'peace of mind'.  Thanks Mr. Sheffield,
and thanks for your well articulated phoneline messages that got me
started in the right direction."
