Hello my fellow PSers Happy Independence weekend!

I was wondering if you can give comments on the below ASET image of an asscher cut I am interested.

This is a 0.42ct 4.23*4.21 stone. I am hoping to use it for a pendant or ring. I am now concerned if it will be too small for either purpose. what is your suggestion?

I appreciate it a lot for your advice!

I’m no step cut expert. I would want several videos to be able to tell. I always judge by my eyes.
 
When you get it in hand, I'm curious to know whether the ASET is more true or the video. The ASET shows a bright center but, in the video, when it rotates to faceup, the entire table looks like someone has "dimmed the lights".
 
That doesn't look like a well cut asscher to me. I'll have to say, though, that I think it's really too small to appreciate the cut at that size. It's too small for most rings, and it will make a tiny pendant. I seriously would wait until you can get at least 5mm. I have one that is 5.5mm and it is in a halo ring setting. I think that size and larger would be better for a pendant or ring.
 
I think it's really too small to appreciate the cut at that size.
I have to agree regarding the size, unless you are aiming for a dainty size. Asschers face up quite small for their carat weight, so be sure to note the dimensions. Unless know you want a dainty size, cut out a square from a piece of paper in the exact same measurements as the diamond and see if it will meet your needs/expectations. I have found that to be super helpful when something is on the cusp of being a potential stone candidate.
 
@Venzen007, @diamondseeker2006, @the_mother_thing, thank you all for the great advice! I am so glad I consulted before I make the order. Now I have decided to give up on this one, and back on hunting.

Venzen007, I have been stalking your posts. The Asscher you found is so beautiful!
 
I dont know why I did not see this earlier.
Large red blobs can indicate issues.
All you have to do to get large red zones is put a set of pavilion facets at or near 41 degrees but doing so compromises light return outside of ASET.
The way to flat top is not helping anything.
Do you have the grading report? Not being able to see it is really frustrating.
 
Flat top, deep pavilion. :naughty:
 
IMG_6971.JPG @Karl_K @flyingpig , thanks a lot for the advice! Always something learnt from PS! I'm grateful that you are so willing to share your knowledge and help people!

I attached the GIA cert. I'm curious how to read it and evaluate a stone based on it and ASET. Hope to learn from you again!
 
The 71% table and 73.7% depth is a big red flag.
With step cuts an ASET image is just an indication not the answer.
In this case the big red blobs are an indication of a problem.
If you look at the video if the ASET was giving the whole picture the areas that are red in ASET would be brightest as the video has a lot of light in the red zone of ASET.
They are not.
 
@Karl_K thanks a lot for the knowledge! Is there a good range of table and depth as an ndicate of good asscher cut?

In general under 65 for the table but occasionally one just over.
Depth is dependent on table size and crown height.
Tiny table with a lofty high crown height a 75%+ depth can be kicken and have better spread than an asscher with a 65% depth.
In general as long as the pavilion matches the crown more of the depth% in the crown is going to be a lot better than most of it in the pavilion.
Since 2 asschers with the same weight and same depth% one can be 20%+ smaller than the other in MM measurements means that depth can be misleading.
In general with the table in the 60s I look for depths in the 60s unless there is a very high crown then might go into the low 70s.
I would look at the mm measurements to decide if the 70% depth was acceptable.
Now on occasion a stone will come along that just rocks it out in the videos and images and I might be inclined to throw some of that out the window.
So the short answer is it depends :}
What it comes down to is the angles and placement of the facets working well together.
 
@Karl_K thank you so much Karl for the tutorial! So glad I learned more about asscher cut!

Posts like this need to be a sticky for peeps hunting down a good asscher! :clap:

@Menlikediamondstoo I know you have your own thread for your asscher hunt, but this may prove helpful to you as well in narrowing down good potential candidates to see in person.

Thank you Thank you!

I have chosen quite a few for my jeweler to bring in and the one I REALLY love and can’t wait to see in person fits well into those parameters!
