Krink, I haven't had time to really play with these babies so just a couple of notes. I don't think
the RegenCZ's are deeper in color, that's probably just my bad pics and the cuts are so similar that at this point, if I mixed 'em up I'd have a hard time telling them apart. They are both 12 sided cuts and both have the H&A faceting, what faceting differences there are, I just don't know.
When I have a chance to loupe both cuts and take better pics, any more info that I can share will be forthcoming.
has a little more info and pics of both cuts from Wink's site.
