Understanding Eye Clean Diamonds And What to Avoid

When you are buying diamonds with VS1 or better clarity grades, you generally won’t have to worry about eye cleanliness. If the diamond was graded by GIA, I can safely tell you that the inclusions will not be visible without a 10x magnification.

However, when you are buying within the range of VS2SI1SI2, you need to know that not all of the diamonds will be eye clean. Also, you cannot rely solely on a grading report or the inclusion plot to tell you how the diamond will look like. 

A Picture/Video Speaks a Thousand Words.

If you are looking for diamonds within the lower clarity ranges (e.g. slightly included), magnified photographs or videos are mandatory prerequisites. I only recommend shopping at websites with such features as it will enable you to make better and informed decisions.

One vendor who does this really well is James Allen – where you get to see REAL photographs and inspect diamonds with an interactive 360° HD video.

What is an Eye Clean Diamond?

Eye-clean is an “unofficial” term which is used to describe a diamond when its inclusions cannot be seen with the naked eye. When determining eye-cleanliness, certain conditions like a viewing distance of 6-12 inches and a human vision of 20/20 are typically assumed.

Do take note there are no set definitions in the industry as different people/vendors may define their own guidelines for eye-cleanliness differently.

Why Clarity Plots Can Sometimes Be Misleading

Take a moment to study the images above. Would you believe me if I told you both images are of the same diamond? You might be wondering why the plot diagram only shows a total of 16 inclusions while the actual photograph of the stone shows numerous black inclusions across the entire diamond.

Well, this is due to a reflection of the inclusions by the pavilion facets. Unfortunately, the grading report will only state the types/locations of inclusions but not the appearance of the diamond. From the GIA plot alone, it might look like an OK stone but this stone isn’t eye clean in real life.

Here’s another example of why viewing a photographs are crucial and why buying diamonds blind is a really bad idea. The stone on the left is eye clean while the one of the right looks really bad.

Even if 2 diamonds fall into the same clarity grade, it doesn’t mean that they will look the same. Does it shock you to know that both of these emerald cut diamonds are of SI2 clarity? And yet, the one on the right is clearly the worse choice due to the location/type of its inclusions.

Like you, I’m a consumer too! I understand that it may be difficult for beginners to perform an analysis by yourself. That’s why I devised a method called the Resize Technique to help you determine eye-cleanliness when buying diamonds online.
