Hi, I asked JP the exact same question and their reply is as below. FYI my diamond has pinpoint, needle and something else. I read somewhere that basically you would want to avoid diamonds with feather and needle so I was really concerned with mine..
"Regarding the characteristics, it shows you the type of inclusions but not the severity.
This is because clarity is graded based on a few factors:
1. The location of the impurities
2. The size of the impurities
3. The number of impurities
Hence, for example, we can have these two diamonds both graded VS1:
Diamond A:
Pinpoint
So even though this diamond only has one type of inclusion, it could be a lot bigger, or there could be many pinpoints, resulting in the grading of a VS1.
Diamond B:
Crystal, Feather, Pinpoint, Cloud, Needle
Whilst for this diamond, at first glance it may seem daunting, but it could mean that all these inclusions are smaller, lesser, or it might even be one of each kind.
When talking about diamond impurities, these are the main concern:
- Durability (prone to chipping or cracks)
- Eye clean (impurities that can be seen with the naked eye)
- Milky/haziness (blurry or oily appearance)"
They helped to check my diamond and mentioned that my diamond was free from the above. You could check in with the jeweller from which you purchased your diamond from to check on the above
