The numbers are good. Ask for an aset if you can get it (or idealscope).
Did you ask if the fluorescence affects the stone? Probably slim but be sure to ask if it goes hazy.
Have you seen a picture of this stone? If you have an image, please post. Do you know if it is eye-clean?
Be sure and ask.
I'm assuming it has a good return policy for whatever reason?
Will it really go hazy for fluorescence stone? From the general feedback from friends and from forum was that fluorescence are not that obvious in smaller stones (<1). Now that you mentioned haziness, I’m getting a bit worried. Lol
