princess cut girdle

[donjeronimo]

I found a princess cut diamond with the specs that I wanted, except that the girdle is "Medium to Very Thick". The other measures of cut seem ok, except for the girdle thickness. How much of a difference does this make on the diamond''s brilliance and overall price? Should I still get this diamond given this girdle if I am getting a good price on it?
Diamond is a 1.5 carat, H VS1
Thanks in advance.
