How can I avoid overpaying for a diamond?
While there's a lot of information available on the Internet to help you learn about diamonds, as a novice, you're not going to be able to understand the subtle distinctions in the stones that can mean the difference between a great value and overpaying for your diamond.
You should have a trained graduate gemologist (G.G.), someone who understands the diamond market and prices, assess every line of your diamond's grading report (preferably from the Gemological Institute of America or the American Gem Society), as well as its "plot," a diagram marking all of the stone's unique, microscopic characteristics and flaws.
RingTutor's impartial graduate gemologists can evaluate the diamonds you select online, or they will shop your preferred online store or impartially shop others to find your perfect diamond.
