I'm having trouble deciding which type of diamond to buy. Any advice?

I would recommend you consider the 4C's when making your decision - Cut, Color, Clarity and Carat Weight. Each of these factors can help you narrow down your selection and make a more informed purchase. Consider what kind of look you want and how much you are willing to spend. You may also want to consult with an expert jeweler for additional advice on which diamond is best suited for your needs.
