I just got my gf's e-ring finished. The diamond is a H&A and I was just wondering if anyone had any idea how common they are. I just thought it would be kind of cool to tell her that this is within the top 5% of all round cut diamonds.
According to my database, there are less than 2.5% H&A round diamonds listed in the internet. I think we can assume for all other diamonds in the world this number should be even lower.
