Which cut adviser is more accurate?

[the-oneil]

Can someone please let me know which provides a more accurate/reliable cut advise

Here Gemappraisers

Or

Here Pricescope


The reason I ask is that, in most cases when I got a (Within TIC range) from Pricescope cut adviser, I also got an 1A grading from the gemappraisers tool, yet in a couple of occasions I got a 1B result!?

 

[strmrdr]

neither, both are guidelines.
In general modern super-ideals fall within 1A with a few features dipping into 1B.
keep in mind that the AGA rules are considered obsolete by their creator.

Storms answer is good.

They are rejection / narrowing down tools to be used with outehr criteria or tools in the place of being able to see the diamonds.

What Garry noted is very important; both systems are rejection tools. They aren''t intended for use in selecting stones; that should be done by a method that involves seeing the actual stone.

The grading report is a good place to start; seeing the stone with your eyes or the eyes of your independent appraiser is the best way to go.
