Every feather extends to surface. At least according to GIA.bcavitt said:Long term this shouldn't be a problem as long as it doesn't extend to the surface.
Agree with RockDiamond.Rockdiamond said:In my opinion, it's totally impossible to give a well advised opinion based on a photo.
As a general rule:
In my experience, such feathers generally do not pose a durability risk- even if there is an area where it breaks the surface.
But it's really a characteristic that must be seen through a loupe, and examined from all angles to really pin down

Pyramid. I"m probably the most prolific appraiser here so I presume I fall into your category of 'experts', and I say that to people regularly. In practice, I usually don't participate in that sort of thread anyway because I also consistently take the position that you can't grade a stone from a photo. That article was written before I became a regular contributor and I"m not up on the zeitgeist before that, but I think you're assigning more malice to the appraisers than they deserve.Pyramid|1460211304|4017244 said:Why do the experts here never mention that a feather is okay if it were a factor in durability it would be
I1 or lower, because that is what the GIA says. Instead we are told the opposite here.
I think he's referring to experts given their experience in trade that market their products with feathers as being vetted for not breaking the surface. Which is rubbish.

GIA defines inclusion in two categories one which are fully contained and others which extend from the surface. Feather is the latter.
Also feathers are plotted where they break the surface (even if visible through the crown) as opposed to other clarity characteristics which are all plotted on the crown unless they are only visible from the Pavilion.
Its so that you know exactly where the breach occurs.

It sounds a bit like an Abbott and Costello routine, doesn't it?Pyramid|1460308392|4017658 said:s things too.
So an inclusion that is a feather comes from within so cannot be colored green like a blemish as it did not start on the
outside? So are cavities only blemishes as they do not come from inside the diamond?
