Hello,

I’m not a stepcut expert and have tried reading most of the threads here regarding asschers. I know that one can’t just look at numbers when it comes to step cuts. I found this stone which weighs 3.78ct, color K and VS1; graded by GIA. The dimensions are 8.69x8.55x6.41. Table is 55% and depth is 75%.

The depth concerns me. Here are some videos from the vendor:




What do you guys think?
 
Depth is rather meaningless when it comes to aschers compare the size in MM.
Looks like a nice crown height which is a good sign.
Can you get an ASET image or some still images?
 
Confirms what I saw in the video, a bit of leakage right at the edge of the table face up but flashes quickly with tilt.
Nice windmills.
Good crown height.
How does the MM compare to similar weight stones?
You can use the PS search engine to find some and compare say from 3 to 4ct with a wide range of color and clarity.
Edit: compare prices while your at it if you can find a comp.
Do you have the gia report number to check the inclusions listed and the plot?
 
Thanks again for your input @Karl_K

I have checked similar weight stones and the mm are within range. The price of the stone is much less than what I saw using the search engine.

Here is the nclusion plot

Do you think with the small leakage, this still a good stone to purchase?

I do not think it detracts from the stone because it flashes quickly and provides contrast for patterns face up.

What I find interesting is the number of bruises and it being grade setting.
I'm not super concerned but I'm going to ping some experts for more opinions to make sure im not missing something.
 
Another question how old is the grading report?
 
Typically, a dealer might consider re-polishing a diamond with a bruising. However, if any of the bruises runs a tiny bit deeper into the diamond than one might hope, it won't get polished away. It might not pay to chase them into the stone and the clarity grade would not be improved by attempting to remove them. What's left, offer it up with some bruising left in place. It might have been polished recently, and this is what remained. Just guesswork, but none of these bruises is likely easy to see without a microscope.
 
I agree with Dave who has seen and graded many thousands (millions) of diamonds.
If a stone has bruises on the crown and girdle that suggests it is old regraded second hand stone - but this one has bruises on the pavilion - so it is part of the rough.
Very unusual.
Dave and other experts - is it possible they would not mention these if the stone was of vastly lower clarity?
 
Dumb questions... but a bruise is damage to the diamond?

Is it even visible in this stone without a loupe?

If not, is it an issue?? :)

Basically its when a diamond suffers an impact of just the right type, one common cause is impact with another diamond.
They are generally very tiny and not eye visible.
I had not seen a stone with this many and it being grade setting on the report before so asked for some help.
After seeing the replies I'm not worried about them.

Thanks, Karl :)

I've always wondered about potential damage to stones, such as when you see that someone's poured out a large bag/scoop of them to make a pretty picture!

I was kind of working on the basis that diamonds are generally too light to do damage to each other unless forcibly bashed into each other, but I guess risk of damage increases as stone weight increases!
 
Is the stone Internally Flawless?
 
Thanks Garry.
