Looks Good But Will It Last?
How can this diamond be SI2 clarity if the diagram at the left (the top view of the diamond) doesn't have any inclusions marked on it?
;)
Beware: The Gemological Institute of America (GIA) only plots on the diagram to the right (the bottom view of the diamond) if an inclusion is only seen from the bottom view, or if the inclusion literally breaks the surface of the bottom of the diamond.
The Key to Symbols discloses that the inclusion is a cavity on the diamond's edge, with an additional feather extending inwards. A cavity is defined by the GIA as a large or deep opening in the diamond, while a feather is defined by the GIA as a break.
