Oh. This is something new to me, why is it better to pick a 0.6x or 0.7x over a flat 0.70 carat?
As mentioned, the stone has potential except that GIA tend to round the lower half to 5%. The optimal is abt 77% but u won’t really know unless it’s a AGS grading. You will find that almost all of JP SIC are at 75% (for gia reports)
The table is fairly wide at 59% which will give more white light return than fire.
All this is of course just talk. U still need scope images.
The other problem is also the lack of the clarity plot to see where the inclusions are located
Personally, I won’t avoid flat caret weights except maybe at 1.0 and 1.5carets. Why do u want to avoid, frankly it only matters if u want to upgrade or sell it. If a jeweller has to take your stone in, repolishing it for example could lose some caret weight, if it drops to the next tier, they lose money. So it’s a lose lose for them. If they offer u a low price at the lower price tier for trade in, u not happy also...
