2 rounds - which should I pick? Idealscope attached!!

[SparkleFairy]

Hi all!

I'm new to Pricescope and researched that this forum has great expertise on diamonds. Please let me know your thoughts on which of the two diamonds below to pick based on the attached Idealscope images for light return, fire, and brilliance. They are both roughly the same carats, cut and clarity and I'm looking to zero in on the Idealscope ASET as a focus to determine which is more fiery and brilliant!! I've also added their GIA measurement and description for reference.

I'm looking to make a decision asap and would love to hear your thoughts.


Thanks in advance.

Both IS images look good. I would choose # 1 based on the numbers though. It has a nicer crown angle than diamond #2.

 

[SparkleFairy]

Thanks JDDN! Should I be concern about the black spots? More so on diamond 1 than 2? Other than that the images are pretty similiar.

 

[JDDN]

The dark areas or black spots as you refer to them are table reflections. It's due to a steeper pavilion and the larger table on the stones you are considering. I wouldn't get too worried about them. The two stones you have there will be very similarly performing based on the specs and the IS images. You could also choose based on spread, i.e. which stone is larger dimension wise.

I think you can do better than both of these. Try for 54-88 table and get that crown angle to be 34-35.

The second idealscope looks a little better than the first, but combining a 59 table and 32.5 crown angle means you'll have a pretty flat-topped looking stone.

 

[JDDN]

P.S. The stones you are considering are 60/60 type diamonds. They tend to face up a tad larger and will be bright at the expense of fire. They will be beautiful, but if you or your SO is looking for a very fiery diamond, these will not be it. Not to say they won't be sparkly and lovely though, as they surely will be!

Thanks diamondseeker2006!

JDDN- I ran the HCA on both of these and returned with a 1.1. for both. Albeit, diamond one is excellent on all four categories versus diamond 2 with very good on scintillation and excellent everywhere else. Wouldn't this determine that the cut would return both fire and brilliant? Is HCA results a good indication of that?

And by expense of fire, how much % are we talking? I definitely want fire in the stone.

Appreciate your thoughts!

Hi diamondseeker2006- another diamond just popped up in my search. Please let me know what you think is the better choice. I'm considering the diamond 1 (VS1) above versus the below (VS2). Please let me know your thoughts. I believe the below has more fire/scintillation than diamond 1, below's HCA is 1.6. Thanks!

Some of the proportions are better (crown angle and pavilion angle) but it is on the deep side. It will probably face up small for it's carat size. The crown angle and smaller table are more in line to give you more fire, but I'm not loving the ASET or IS.

Have you seen a diamond like the first two? Some really love the look and it is a preference. They are not bad diamonds.

It would be great if you could see a 60/60 type diamond in real life. If you like it then the first 2 options you have are good ones. If not, then keep looking and stick with the proportions that diamondseeker gave you. But I would pass on the stone you just posted b/c I think you can find better.

Hi JDDN- I have not seen a 60/60 diamond in person. Would you have somewhere online (images videos) where I can reference as I have been unable to find online. Is there any specifics about a 60/60 diamonds and how it looks compared to deeper cut diamonds? Thanks so much!!

Your 3rd stone with the 35/40.8 angles would probably be my choice. It will get you more fire. Most (but not all) PSers will
go up to a depth of 62.3. The 60/60 stones do usually face up larger for the carat weight but I personally like to see the fire.

You should not be able to see anything with the unaided eye in a VS1/Vs2 top down view. If its important to you, you should ask if
you can see anything from the side view.

 

[SparkleFairy]

Thanks Tyty, would diamond 1 be absent of all fire or will there be some fire but with more brilliance? From the HCA, I had assumed that there'll be a combination of Fire and brilliance at the same time. Thanks for your comments.

 

[JDDN]

The problem is that you really need to see one in real life to appreciate it's cut and decide if you like it. The fire flashes appear in different lighting and so capturing those nuances on video is difficult. Really it's the same with all diamonds. Much of their personality comes out in different lighting, different environments, etc.

Here's an article on 60/60 stones. For more fire in a diamond, stick to a higher crown angle (34-35) and a smaller table (55-57%). I would try to avoid a pavilion angle greater than 41 degrees as well.

I had a stone similar to the first 2 you posted and it did not have enough fire for me personally. It faced up very bright and white and I got lots of compliments. But for me, over time, it lacked the "personality" I was looking for. That's why I say it's all preference b/c some people love 60/60 type stones. It does sound like you want one with more fire though. If these were your only choices, I'd choose #3 for that reason.

Hi all-

One last option. Please let me know your thoughts. I'm swaying between diamond 1 and this one. Thanks so much!

 

[JDDN]

They should look very different from one another. If you are looking for some fire in your stone, I would choose this last option. It has a smaller table and a higher crown. Also the pavilion angle is a nice complement to the crown angle. Looks like there is some slight leakage under the table, but from the experts on this forum, you should not be able to notice it. If it were me, I'd lean towards this last one over the first one. That's a matter of preference though!
