SI2 can be eye visible
the numbers are meaningless - request an ASET or at least an Ideal-scope photo. Good sym and polish is a worry

Off set culet''s give this problem - that is the most common ''worry''. And the 4 big P1 facets are so close to the octahdra plane they can have a bad polish and dull the stone.

Calm, no problem... Still, I am trying to understand why a Good/Good should be an issue to worry? If a Diamond can have such a bad culet position and still get a good grade for sym..., I would agree with you. |

I saw the "diamond map" in the store and nothing jumped out at me. I know there is a small inclusion that I couldn''t see until it was magnified 20x When viewing it under magnification, I was pleased with the symmetry and nothing looked "off" to me.
I was just basically seeing if the specs on it were respectable. |

A) an SI2 inclusion will be easily seen with a 10x by any professional!!! B) I have encountered numerous ''professionals'' in this business that had no clue as to notice or grade a Diamond cut or its symmetry... As far as the specs.., the numbers seem more than fine..., but numbers dont mean a lot!!! Your eyes do mean a lot! |
