It is very important that a Marquise Diamond is rectangular shaped because this will ensure that light is evenly distributed. There are several colors you can choose for your marquise diamond such as blue, green, and white. However, you have to ensure that the color matches the personality of the person you’re getting the gift for. For example, a white marquise diamond is perfect for someone that has a shy personality and doesn’t really care about the latest trends. There are specific things that customers need to consider when they’re purchasing marquise diamond. The most important thing is to ensure that the diamond is protected by elongated prongs. This is because the diamond’s ends are extremely delicate and they can easily be damaged. Customers should also try to purchase a ring that doesn’t have a maximum bow effect. This can result in the diamond having a black spot in the middle which definitely affects its appearance.
