How to Find the Perfect Wedding Band to Match Your Engagement Ring
If your engagement ring has a flat surface underneath the gallery like the ring shown, a flat band will fit perfectly flush with it.
(Meaning the band will sit closely to the ring with no gap).
Make sure that the band's concave matches the ring's convex.
Like the example below: if your ring's convex is 3mm, you will want to make sure that the band’s concave is 3mm. Otherwise, there will be a gap, meaning they will not be flush.
Lastly, who said you can only have one band for your ring? Have different styles to fit your different moods!
