On #2, the grade setting characteristic is listed as Cloud. That most likely means on the table. Now, it is a VS1, so it could be very small. However, since we don’t have a plot because it if under 1 ct., we don’t know where it is. With that said, you can actually call GIA to get more info about the grading of that stone. Also, I definitely do not like the 60% table, period, and also paired with a 14% crown height. You are going to lose fire and also you will have a flat top appearance of the stone. The pavilion angle is also too steep. Also, #1 stone is D color and that’s fabulous! There is a slight difference between D & E down to F.
In my opinion, yes. However, if you want to run both stones through the HCA you should. The other stone does have a small cavity at the girdle edge. So you should be aware of that. However, I do not thing it should be an issue given the stone is a VS2 but you should discuss with the vendor. Who is the vendor? Let them do their job and sell you the stone. Ask them a million questions until you are satisfied. This is a lot of money (especially with the D!) so let them work for the sale.
