OK, warning, this is a basic question, but if you dont ask you dont learn
. In the eternity bands I have been looking at on the inside of the ring some (most) have a small circular hole / opening where the diamond sits on the other side. what is the purpose of this? Is that to make the ring lighter, less metal? Is it to allow the ring to get cleaned better as you get to the diamonds from the bottom, or does it make it worse as dirt gets more easier trapped in from the underside. I have attached a post of one ring that shows this - but I am not refering to just this ring, but in general styles like this that have this feature. I have been looking at one particular ring that doesnt have the holes, but I have seen them everywhere, so now I guess I am wondering is it a design flaw not to have them?? Hope that makes sense, and thanks for educating us newbies.
