Dark facet on table, is it typical?

[Heidibrooke]

I received the 1.07 F diamond today, to compare to the 1.08 G. I will include links and certificates for both below.

Right off, I’m noticing that the F has that dark triangular facet when tilted. The H (returned) had this as well. Can anyone tell me if this is a typical facet or is the tilt angle of the G more preferable? I’m wondering if it has something to do with the CA/PA having a better relationship/combo? I would be so appreciative of your thoughts! I am learning so much from the experts here.

Also...there is only a .01 difference in weight. I didn’t expect a visual difference in size. Does this seem accurate?

 

[Heidibrooke]

Update: I think the dark facet is being caused by the dark lumen of the diamond viewer device.

Still wondering if the surface area is still that much less on the 1.07. Thoughts appreciated!

0.3sqmm is completely negligible to the naked eye. I personally not consider this tiny difference in my decision at all.

Are you able to see that side dark facet when you perch the stone on the top of your hand, like this example, and then tilt your hand to see the side view? Edit: You already discovered the cause of the dark facet

looking at diamonds from that steep an angle tells you nothing about their light handling.

Thanks so much! In the palm of my hand, the dark facet is much lighter. I don’t know why I didn’t realize it was the holder that was causing it.

As for size difference, all 4 of my kids selected the 1.08 as the larger stone. However, I believe the thicker prongs are playing into their ability to notice it as being larger.

Thanks so much, Karl. I’m completely overthinking this...story of my life. Lol.

 

[Heidibrooke]

Anyone want to make this decision for me?

Does anyone see issues with the arrows on the F, particularly the points not being as crisp?

Does one have “better” inclusions than the other?

Better overall appearance?

Can’t say anything with only 1 picture from the side

I provided links to each diamond in the first post and added a couple more below. Thanks!

Adding a couple of photos.

My family members are saying they can visually see the difference in the size of these diamonds. So, of course, I searched PS and it seems some people can see a .3mm difference. I will attach the diagram of size comparison. @diamondseeker2006 would you care to comment? I think you are one who is able to detect .3mm differences? I feel like I see the difference but my eyes may be playing tricks, lol.

The difference between the two stones is actually only .03mm and I’m not sure how anyone could detect that with the human eye.

Maybe it’s bc one is set and the other is not. Optical illusion

I'm almost certain it's this. For comparison, a fine mechanical pencil lead is only .5mm wide The difference in diameter between these stones is only 0.04, or about 1/12 of that pencil lead. It's the prongs in the setting that make it look bigger.

Thank you for taking a look and replying. Diamdb.com said 0.3mm, so that’s where I was basing that figure. It makes sense that it’s the thicker prongs on the diamond that is set. That’s what I thought too, but they even guessed which was bigger on just the diagram. Lucky guessers I think! Lol.

Great visual comparison, thank you! It has to be the prongs.
I’m trying to convince myself to love the F 1.07 more because I have to send the ring back regardless because of a prong adjustment. There is just something a little bit unusual about its arrows though.

Adding a couple of photos.

In this photo, I like the unset diamond on the left more. It looks whiter. But that might be because the set diamond is set in yellow gold. I always prefer whiter. And I like the arrows I can see on the left diamond. And the left also looks bigger, again maybe because it looks whiter, and that is because it is not set in yellow gold. For me, when I look at two stones of equal size, and let's say even equal cut, the whiter one will always look bigger to me. my 2 c.

 

[diamondseeker2006]

I think diamb is measuring face up area, not diameter. When we say we can see .3mm, we are talking about diameter...so a 6.5mm diameter round and a 6.8mm would have a .3mm difference in diameter.

Your stones' diameter averages are 6.55 and and 6.58, so as someone has already said, the difference is .03mm. These stones are fine as a match as far as diameter goes! You can't see any color difference?

Are you choosing one stone or trying to match a pair for studs?

 

[diamondseeker2006]

I just looked back at your prior posts and see that you are deciding whether to keep the G. I will tell you that I don't like the inclusions in the F. It has comments to the side of the clarity plot that says additional twining wisps, pinpoints, clouds, and surface graining not shown (on the clarity plot). I can see it in the video. I would be afraid this stone might be a little hazy in sunlight. The F does look whiter in the pictures, but I think you could do better than this particular stone.

Thank you! I love this type of feedback. I want the honest truth. Unfortunately, the G has the same additional comments. It has been dreary and raining here since Monday, so I haven’t been able to look at the F in sunlight. The G doesn’t seem hazy in direct sunlight. I can easily see inside the stone, if that makes sense. What are your thoughts on the G? It’s just as bright and white as the F, as far as I can tell. I’m going to share more photos below. Thanks again! Oh, and this is replacing my ering. So I will be returning one.

I truly appreciate the feedback! I agree with you, the G looks warmer in this photo. I will include more photos below, if you have time to take a look. Thanks again!

 

[Heidibrooke]

I feel like the arrows are more visible in the F because prongs aren’t covering 4 of them. The G arrows have a break in the mid section of all 4 that are under prongs. Here are some comparison and some of the G in sunlight.

Diamond are complex little doodads of facets that behave like windows and/or mirrors.
Windows let light through.
Mirrors reflect something that is in that room.

Mirrors mean when you look at a diamond you are also looking at reflections of the room, or the blue sky, etc.

At that angle, that facet reflected something in that room that was dark.
That's all.

 

[diamondseeker2006]

Wow, you did an amazing job with this last set of pictures! I will have to say that the G looks good in all of those. Don't worry about what's happening with the ends of arrows when a stone is set. You'll have prong reflection and it's not the same as looking at a loose stone. I feel like I can see the clouds in the F more so than the G in these last pictures. So I wouldn't consider the F. Can you look at any G VS2's or are they out of budget? It's just problematic because you have to spend double at JA to upgrade, so you really need to get the best stone you possibly can now if you plan to keep it a long time.

 

[flyingpig]

I would go with the G.
I think G is a tad more transparant with less scattering of light than the F is bases on these photos.

I hate their upgrade policy. My husband says I can upgrade again in the future but I’m no spring chicken. There was one H VS2 in budget but I felt my G oval (right hand) made it appear too warm. I sent that one back.

I wish I could see what you are seeing when you see clouds and dispersion of light. I have given myself headaches trying to examine diamonds with these aging eyes, lol. I have taken hundreds of photos and videos and try to see these things but I just don’t know what to look for exactly.

As for the arrows, do you think I should ask JA to rotate the stone so that all arrows are visible or will that not make any difference in performance? Also the diamond is very low set. Would raising it slightly make any changes for the good?

Thank you so much for all your help! I don’t know what I would’ve done without all the nice PSers and the wealth of knowledge and information on this site.

You have been so helpful! I appreciate your comments more than you know. I’m so tired of stressing over this. I’m glad you can see things like transparency and light scattering. Thank you!

One last question, would you change the orientation of the G to uncover the arrows? Would that make any difference in performance?
