Emerald Square Cut vs. Cut-Cornered Square Step Cut

[creeks]

I am desperate for accurate, to-the-point knowledge about what GIA considers the difference to be between an Emerald Square Cut and a Cut-Cornered Square Step Cut. Any information is greatly appreciated!! I understand they are both generic asschers, since it''s a registered name. Is the only difference a slightly more dramatic corner on the cut-cornered square step cut? Or might it also have a greater windmill effect, and more closely resemble a Royal Asscher?

Thanks so much for any response!!

Hi!

I love a challenge! So your question gave me reason to research.

Take a look at this thread:

Mostly, I found that a square emerald cut diamond is not the same as an Asscher.
I also found something called a Lucere, very cool, kind of 1/2 Asscher and 1/2 princess - which falls into the cut-cornered square step cut category.

Read the thread, it''s a lot less confusing that I am

Same... except the pavillion on the "Cut Cornered..." will have more the 3 or 4 step facets on each side... probably 5 or 6...

It would probably mean for the crown the same... (but on the crown i am not certain)

No... you are talking about proportions and corner breaks... the name on the cert would most likely imply a few more facets. That has nothing to do with patterns or deep cut corners.

You may find no-name step cut diamonds that do have extra facets like the RA, but not the tell-tale proportions and they surely look nothing like. IMO, 'normal' square emerald cuts with matching proportions have the look allot more.

These attached here are 'normal' square step cut... Bad?

And the next two posts have examples of the other kind - not the most extreme non-asscherish I could find - just the first two that turned up on a quick search.

Hope the 0.2 helps
