Recently, a reader in the midst of shopping for a diamond proposal ring sent us an email about a couple of SI2 and VS2 diamonds he had shortlisted. One of the diamonds had a comment in the GIA report which states “Additional pinpoints are not shown”.
So he asked: “What does additional pinpoints not shown mean? Is this good or bad? Should I be concerned about it?”
Wait!!? What are the comments in the GIA report referring to?
Paul’s Answer: Pin point inclusions are basically tiny mineral crystals embedded inside the diamond. Usually, pinpoints are so minor that they won’t affect the diamond’s clarity rating when it is being graded in the lab.
The sentences “Additional pinpoints not shown” or “Pinpoints not shown” in the comments section refer to the same thing. They are written there to complete the report and to allow 3rd party appraisers to be aware of other inclusions apart from those already listed in the clarity plot.
The first reason is that these pinpoints are so tiny under 10X magnification that if they were to be plotted, they would look more severe than they are in reality. The second reason is that the pinpoints could be so numerous and widespread that it complicates the plot unnecessarily.
Here’s an example to illustrate what I mean.
Because the inclusions are so small, you can’t even see the tiny dot on the plot unless we purposely enlarge the diagram to show it proportionately. The bottomline is, when clarity characteristics like minute pinpoints are not required to support the clarity grade or diamond identification, they may mentioned under the Comments section instead.
The short answer is no. Regardless of seeing this comment in a VVS or SI diamond, the pinpoints will never pose a problem. In lower clarity ratings, the grade making inclusions are never the pinpoint inclusions but other types of inclusions.
Just to be clear, pinpoint inclusions will not cause haziness, durability or eyecleanliness issues regardless of the diamond’s clarity rating. Let’s take a look at a couple of real life examples to illustrate this…
For both SI1 diamonds above, the grade making inclusions are clouds (indicated by listed order) and the pinpoints are actually extremely hard to see even under magnification. I want you to click on both listings and examine the diamonds for yourself.
And by the way, HD magnified videos like those provided by James Allen enable you to take the guesswork out of buying diamonds and visualize exactly how they look like. It offers transparency and allows you to shop with confidence.
Next, I want you to take a look at the following VVS2 diamonds and I challenge you to identify the exact locations of the pinpoints. Let me know in the comments below if you can actually see them under magnification.
Again, click on both the listings above and you will see how challenging it is to see the pinpoints. This is also why I said that pinpoints would never be an issue with eyecleanliness or pose any problems to the beauty of the stone.
To wrap things up, you don’t have to worry about comments related to pinpoints in a GIA grading report. They are the most benign type of inclusions to have in a diamond.
If you are buying slightly included (SI) or included (I) diamonds, they will have to be judged on a case by case basis as it is often the other listed inclusions that may cause issues.
