7 stone radiant band- stone size help!

[sparkleandfire]

Hello, I am having a custom 7 stone radiant diamond band made. I wear a size 7. My question is what is the biggest stone size that will still be comfortable on the sides of my finger? Anyone have a similar size finger and can give some input on what stone size to go with??

You should aim for the 7 stones touching to run 24mm to cover 1/3rd of your finger.
Size 7 is 54mm insider circumference. Allowing the diamonds to be up a bit higher by 3ay 3mm the equivalent of 73mm circumference.
If the stones are higher you need more. Lower a bit less. So each stone needs to be about 3.4mm wide. To make it easier to find nice diamonds - allow say 3.6 to 3.8mm in the center and take a slight graduation.
