While inclusions are the naturally occurring flaws within a diamond, blemishes are the imperfections on the surface of the diamond. Below are some of the most common flaws that occur on a diamond.
These are the holes present on the diamond surface, which occur in varying sizes and locations. They have the ability to influence the stability and durability of the diamond. These flaws are very visible when they appear on ornaments like flat diamond rings.
Chips are the shallow indentations appearing on the surface of the diamond. These occur due to the errors while cutting the diamond. Sometimes, these might be positioned at the edges and cause feathering; these are called bruises. They can be detected by diamond clarity plot reports.
Sometimes, there will be very small inclusions found on the surface of the diamonds. It is very difficult to distinguish these from each other even under magnification. Since they appear very similar to a translucent cloud within the stone, they cannot be detected with the naked eye. Because of the same reason, these flaws do not affect the clarity grades of the diamond.
