I love Emerald cut diamonds- well, certain Emerald cuts. This is a great one.
It flashes bright white bars of light with even a small amount of movement.
The corners are nicely chiseled- creating generous sized triangular corner facets.
The diamond has enough body color for GIA to grade it M color - yet the face up is quite white. Could be the faint fluorescence is a help and the cut certainly produces a lot of white flashes that hide body color.
The stone is eye clean.
Any specks you see in the pictures/video are dust.
The stone looks great in person
