Do you have a real image of the blown up stone? Can you ask the gemologist what they see under the table? Is it alwasys showing up darker or
"different" from the other facets under the table.
If you arent super picky it may be fine, but if you want everything under the table to look the same...? You didnt say what size this stone is. The
smaller it is the less likely you will notice anything.
Can you post the "real" image of the blown up stone?
I've also just had a look at this one, same size/characteristics but better light return (HCA 1.3). Not quite as symmetrical (still GIA ex) but doesn't have nearly the same number of the smaller dark constrast returns.
Thoughts?
