BN Asscher - my Aset image. Thoughts?

[Venzen007]

Hi, all

I received the first stone from Blue Nile. This was it: https://www.bluenile.com/diamond-details/LD03354446

I'm not exactly sure if I'm doing the aset scope right, but I've tried to read what I can on it. I'm attaching several aset images I took with my phone. Top left is outdoor lighting. The rest are indoor, office lighting.

What do you think? I can make it look different ways, but on average, I'm getting a consistent white to green middle portion. Good, bad, indifferent?

The ASET says that the patch under the table is not as bright as the rest. I am not perfectly convinced this is a fault every time, everywhere.

Once you receive your diamond in hand, I don't see the need for an ASET. I use an ASET if I was buying site unseen and before I have it in hand. But since you have the diamond in hand... are you able to compare to others and more importantly how do you like it?

Since you have it in hand,you can now view it multiple lighting situation, and not just one from a vendor.

 

[Venzen007]

From my limited experience, even average cut diamonds throw off enough sparkle to make it difficult for me to see exactly what I'm looking at. I sort of like the Aset scope view because it, supposedly, takes all the visual flash and translates it into something that's easier to see/quantify.

Does that make sense, or am I totally going about this wrong?

Here is a an ASET comparison chart for different shapes. https://beyond4cs.com/grading/aset-reference-charts/ ASETs, lab reports and video can narrow down selection but the final judge is you. Is the diamond pleasing to the eye of the wearer in normal lighting conditions?
The ASET shows a stationary picture of where light is returned, where light is indirectly reflected and where light is obstructed. The white and black areas of an ASET picture are areas of light leakage. Again this is a stationary picture and the areas will change as the diamond is in motion.

Back light is way to bright and not even enough behind it and the diamond spears to not be into the scope enough,.
The area outside the table is great but the area under the table is not clear due to the problems with the images if its ok or not.
The images are showing a lot of what looks like leakage but is lighting problems.
A computer monitor with a white screen from a foot to 18 inches away in a dim room is generally perfect lighting.

 

[Venzen007]

Thanks, Karl, but all of these were done with only ambient light for backlighting. In each one, the diamond is in a tension setting just sitting in the jewel box it came in, no special lighting directed at it from any direction.

There's a chance my phone's camera enhances the light coming into it, since, except for the outdoor picture, these should really have been dark, considering I'm sitting at my desk, hunkered over the jewel box on my lap with the asset scope and phone directly over the stone.

I'll try the computer monitor this morning when I get into the office. I'm getting another diamond in the mail today and tomorrow, so I'll shortly have three to directly compare.

Ok, Karl (and anyone else interested). Today, I laid my computer monitor in my lap. Went to a blank white MS Paint screen, and used an acrylic plate with a diamond depression (thanks David Atlas) so the stone would stay face up and put it right on the monitor screen. I set the Aset scope and the Idealscope directly on top of the plate, and photographed with my phone through the scopes. I do like how consistent this was! Here they are. Any thoughts?

Great job on the DIY photo setup!

@Karl_K will probably have additional commentary as he is an expert in square step cuts. But the light performance looks pretty good to me.

I am curious about the culet area. I would want to take a close look with the loupe and make sure there are no abrasions.

 

[Karl_K]

much better images!!! ok, I would rate it as very good, more red in the center would raise it up.
But aset is not diagnostic just suggestive.
When comparing this one to the others pay attention to the under table area.

It has a medium culet per the report.
Nothing to worry about.

For what it's worth and I'm just a novice on this board, it's a very pretty diamond. What plans do you have as far as a setting? If you do keep it, I hope you'll send pictures of the finished piece.

The 2nd of 3 stones has arrived, and here are its Aset and Ideal, using the same method.

I have to say, with both of them side by side outside in the natural light, this second one seems to be outperforming the first one, in terms of what is going on under the table.

 

[Karl_K]

vg again, which one is this in the other thread?

Does there not appear to be a lot of leakage under the table in these images??

Oh, yeah. This second one is https://www.bluenile.com/diamond-details/LD11185320
