Poor Polishing?

[molecule]

@Serg
On your home page of cutwise, you have a round cut diamond that has some odd polishing marks and/or CVD growth striations. View attachment 772343 View attachment 772344
Could you go into a bit of detail here on what the cause of the markings is and how it would affect the store of the diamond?

I believe it is natural diamond.
