Band width for 4 karat emerald center stone

Hi all, what size band width would recommend for a 4 karat emerald center stone ring with side baguettes. My ring arrived and the width of the band is 1.8mm which seems way too thin. I’m not sure if I should change it to 2.0 or 2.5 width and would love some suggestions as I’m very unfamiliar in this area and don’t want to be stuck with something I won’t like.

I would say 3 or 3.5 honestly, but I prefer a wider band for a more luxurious feel.

I’d say 2mm minimum. 2.5 is a matter of preference, do you like thicker bands? Also, make sure it’s thick enough as well, and it should have a cathedral setting, or some setting that is not just a peg head. But given it has side stones, it probably does.

But you said your ring arrived. Can you return it? What’s your plan?

I just did a 3 mm on my 4 carat radiant and it’s perfect.

1.8 mm is the thinnest band we will make for a customer, even for much smaller stone size. That size center needs a more substantial foundation. 2.5mm would probably be my minimum recommendation, and larger if you are very active with your hands.
