There are probably no structural issues if that's what you are worried about. VS2s are usually eye-clean but cant really comment
from just a picture of the map. You probably have nothing to worry about but ask the vendor.
Definitely, definitely check with their return policy! That was huge for me and I took advantage of it twice. PS recomended vendor also to be safe if u r a newbie like I was. Takes more risk out of the purchase. However you stated it is a local vendor. Hopefully you have checked out the reputation, BBB, etc. Never can be too safe.
VS2 should be wonderful. Paying for a VS2, should be eye clean. You have seen this diamond in person, since local? Or just the certificate?
I would ask about the feather directly. I have found that if I didnt asked *point blank* questions then sometimes the answers came back a little muddled. I believe I read up a lot on feathers and most of the time they seem to be ok, but there can be small risk at time (lower quality I believe)? Try a search. Lots of threads.... but each time it is unique, may just need to ask your vendor point blank.
If possible you could always take it to an independent appraiser to give it a once over. Being a VS2 probably isn't necessary with a AGS, assuming you know price is competitive. I did this with one of my GIA SI2s I was going to purchase. Was a total waste of my time and money. Pick wisely.
H and A should be stunning you could also post any other information you have measurements, scopes Exedra and get feedback from others (not me lol). It was helpful. Being H&A AGS should be good to go!
