What are the advantages of getting a round diamond instead of one of the other shapes?
Research has shown that about 70% of people upgrade, trade-in, or otherwise obtain a better or larger diamond later in life. It is in this regard that the round diamond has a major advantage. Round diamonds account for about 90% of diamond sales. Therefore, later on when you want to upgrade, you will be in a much better position if you own a round diamond, because that is where the strong market is located. You can usually make a nice profit on a round diamond after 10 or 15 years. But with other diamonds such as a heart-shaped diamond, it is not unusual for you to sell it for 50% less than you paid for it, because there is almost no market for such an item.
