Will try to keep this short.
The edges weren't as bright as other parts of the diamond in certain lighting. I thought that was normal, but I still didn't like it. Turns out it doesn't have to be normal. Better cut and super ideal stones don't seem to have that problem. Resulting in those stones actually looking bigger to me. Tiny slivers in the center didn't seem to light up in certain lighting. Thought that was normal too, and it still annoyed me. Super ideal does not have that issue (at least not to me).
Thank you for that. It is helpful to me!!
