There have been some discussions on the differences.
Karl and others will help I am sure.
The main point for me is that an asscher must have rich repetitve patterns AND decent corner facets creating windmills.
a DIVE INTO A WISHING WELL EFFECT
here is an example of a diamond with windmills but NO REPETITIVE PATTERNS.

The biggest thing is that GIA wont call an asscher an asscher.
So they call both square emeralds(keel culet) and and some asschers(pointed culet) the same thing.

I would call that one a badly cut asscher.
The p2 angle is off.

Some asschers but not all are called square emerald by GIA but not all stones called square emerald by GIA are asschers.

When it comes to step cuts, there’s a certain magic I look for.
Unlike round diamonds, there’s really no formula that works.
I do adore large corners- but that doesn’t always work ( just look at Garry’s example)
It’s each stone for itself.
Even the GIA shape designation don’t do it.
“Octagonal Step Cut”
I love the sound of that. But unfortunately I’ve seen stones classified as such that barked.
On the other hand I’ve seen stones classified as emerald cuts that have knocked my sox off.
This makes life so much more interesting that when looking at (boring) round brilliant cuts.
Use the force ( your eyes) Luke.

And what then is a princess cut?
What we know as a “Princess Cut” would be classified by GIA as “Square Modified Brilliant “
Like what we think of as an “Asscher Cut”- GIA does jot use the commonly used nomenclature

Since people of trade are on this thread.
I just want to ask why are large square step cut diamond or Carre cuts so hard to find?
Do they fall under the not popular problem?

I always thought emerald cuts were more rectangular shape?
And what then is a princess cut?
Emerald cut with no other modifier is rectangular at or over 1.05 l/w ratio.

A princess cut is a different type of cut than an emerald cut.
Emerald cuts and asschers are step cuts.
The facets run side to side horizontal to the table in a step cut.
They look like steps when viewed off axis, hence the step cut name.

The princess cut is a square modified brilliants, the pavilion facets ran vertical to the table.

I did hear an explanation once of why GIA do not apply trade or trademarked names on cuts (as AGS will). I suppose they do not want to get involved in legal wrangles.
IMHO once a patent has expired and there is no longer any legal protection I feel GIA should apply the trade names.
e.g. Radiant, Princess, Cushion Brilliant, Asscher etc.
Asscher would be the most difficult because the boundary between Square Emerald and Asscher is in my opinion a look rather than a facet style

My asscher is listed as a cut cornered square step cut instead of square emerald on the GIA paperwork. Is this due to the degree the corners are cut? They do not look any more clipped to me than a square emerald cut.

I gave up predicting what they will call a step cut .......ometimes I think they roll dice to name them.

My asscher is a RA clone. Could that have anything to do with the GIA designation?
I think there is more chance that men will ever learn what women think than anyone working out what or why GIA do things

Easy solution to the name problem. Laser inscribe the name on the girdle (GIA will even do it for you for a small fee)
Then the name will appear on the report. You can even call your diamond Harry.
