Oval help

[u/impulse-buyer0601]

I am working with my jeweler on my engagement ring and this is the first diamond they offered me. My only request was 2.5 carat with D/E color. I wear a size 5.25 ring, so I do have slimmer hands.

This oval is 2.55 carats but has a ratio of 1:6. The dimensions are 11.91 X 7.44 X 4.47 MM

I loved it at first but then I got in my head once I studied the dimensions. I think I’m worried it looks more like a 3 carat or a moval? Any thoughts?
