How does this sound??

H SI1 could get a much lower grade from GIA.
Does the stone appear yellow and can yousee the inclusions?

Have it sent to an appraiser.

Cut looks good though.

My main concern would be the yellow fluoresence, and the clouds not shown comment as graded by EGL.

GIA has stricter standards in grading than EGL, though EGL USA is making successful attempts at stricter grading, too...so it´s hard to know how accurately graded your diamond is.

The yellow fluoresence might make the stone look yellow, and the clouds not shown might detract from it´s sparkle and brilliance and make it appear cloudy (even though it´s an ideal-cut stone)!

If you´ve seen it, you can compare it to other stones and evaluate if the fluoresence or the clouds are affecting or not.

If you haven´t seen it and are purchasing through the internet, then taking it to an appraiser is a good idea (only check on the seller´s refund policies first!)

Best of luck!
