'The IGS Diamond Buyer's Guide' contains the most comprehensive study on diamonds that I have found in one book. The information provided is
extremely useful and easy to understand. It can be used by the most
amateur diamond buyer to get a great diamond for a great price. It's so
easy to be misled when buying a diamond. And if people read just one
book to understand what their buying, I would highly recommend that this
guide be the one.'
