Diamond Education Diamond Clarity Diamond Clarity refers to the presence (or absence) of impurities, blemishes or other identifying characteristics within a diamond. Clarity characteristics are what make every diamond completely unique. There are no two diamonds that will have exactly the same inclusions in the same location. There are five factors that determine how a major laboratory like GIA or AGSL will assign a clarity grade to a specific diamond. They include: •
Size: How large or small is an inclusion within a diamond?
Number: How many inclusions are found within a diamond?
Position: What is the location of the diamond’s inclusions? Inclusions located under the table or “heart” of the diamond affect clarity grade more so than inclusions located under the side facets.
Nature: Do the inclusions affect the durability of a diamond? Large feathers can be hazardous depending on their exact size and position within the diamond.
Relief: How visible is the inclusion? Dark inclusions are easier to locate than a white or clear inclusion and may be graded more harshly.
Which Clarity Grade to Choose? It is important to select a diamond that does not have any inclusions that will effect the overall beauty and durability of the diamond. If you want to be 100% sure that your diamond will be completely clean of "eyevisible" inclusions, stick with diamonds graded "VS2" or higher. Shopping for SI quality diamonds can be very rewarding, but it's best to have those diamonds reviewed by our expert staff before finalizing your order. This will ensure you receive a diamond that does not have any inclusions visible to the naked eye. It is also a good idea to balance the clarity grade of your diamond with the color. If you are looking at diamonds in the DF color range, focus on clarity grades of VS2 or higher. Diamonds in the GI color range combined with SI clarity are excellent values.
