When you are free can you find me one that's exactly 1 carat. I thought 1.10 would have fit but now they're saying it needs to be 1 carat only. No rush just whenever you are free thank you!
Not finding anything in the 1.00-1.03 range that is well cut and proportioned.
But, if we look at diameter:

If this wide and shallow 1.00 carat at 6.54mm would fit since it it exactly 1.00 carat (but don't buy this horrible diamond), then this 1.07 carat at 6.56mm that I recommended before should have no trouble being mounted.

Please confirm with your jeweler what the max millimeter diameter of the diamond can be for your particular setting, not what they tell you to limit yourself on carat weight since exactly 1.00 carat diamonds come in quite a wide range of outer diameters.
