Diamond prices depend on how a diamond is cut. To ensure its value, the cut should neither be too shallow or too deep. When the time comes to buy a diamond, sometimes it gets a little stressful as you walk into a jewelry store and feel like you might be being put on. The price of a diamond is determined by assessing its color, carat weight, cut and clarity level, four characteristics that are generally referred to as the 4 C's. Based on the various pricing of the diamonds you can gift a beautiful diamond to your loved one and make her happy.
