need info on these stats

[ajdubya126]

my boyfriend found a diamond on WF that we can both agree on the style and price. Obviously, we'll get a pic of the diamond before we buy especially since it's SI2, but what do you think of these stats? Any glaring no-nos before we request a pic.

since I want an oval cut diamond, I'd like a four prong setting. Are there any major disadvantages for a four prong when compared to a six prong?
