Carat weight is an indication of a diamond’s size. One carat equals 200 milligrams. The marquise cut diamonds offer the biggest size per carat weight among all main shapes of the gem. This makes for a 5 ct diamond ring with a larger-looking diamond for what you pay for. Although jewelers use exact carat weight in advertisements of diamond rings, the marquise cut stone’s size is subject to vary slightly. The right carat weight will be mentioned in the GIA laboratory grading report presented alongside your five-carat diamond ring, of course.
To get the best possible value, it is best to choose a diamond with slightly lesser carat weight than what is advertised. The savings you get from that can be used to upgrade the diamond cut, which dramatically improves its brilliance.
When it comes to color grade, it is advisable to choose one that falls under J to L color scale by GIA. When it comes to clarity grade, on the other hand, it is best to go for SI1 and SI2. Those clarity grades by GIA suggest that although there are inclusions, they are usually invisible unless a magnification scope is used to find them inside the gem. This way, you can cut down the cost of the 5 ct diamond ring to a much lower price.
