Will this ring fit this setting?

[blingy0722]

I have two platinum settings without stones. The first setting held a round brilliant that's 6.87 x 6.89 x 4.22 mm. The second setting held a cushion cut that measured 8.71 x 8.39 x 5.70 mm.

Finally, I found a stone that I like - a round brilliant that's 7.63 x 7.66 x 4.71. Will this stone fit either of these settings? Thank you
