Hi,I'm new to this whole diamond thing but recently got engaged and am now looking for that perfect ring. I've looked around and I like the squarish cuts, but not the emerald. I like the princess cut, but was looking through some websites and noticed the radiant cut as well, but can't really find a good explanation as to the difference, other than the fact that the radian has tapered corners. Is there a difference in terms of brilliance? Any guidance would be much appreciated.
