What do you think about these two diamonds?

[Lucie]

Well, I''ve been looking at settings for months and now I''m ready to pick out a diamond! After hanging around in pricescope for at least 4 months, I thought I knew a thing or two about how to tell if a diamond is any good or not, but I really want some "expert pricescope" opinions! What do you think about these two?

Numbers are promising. Post the IS/ASET image. And also the hearts image for the ACA.

Stone-Cold11, thanks so much for responding. I've been trying to get the reports to upload but I'm having trouble and falling asleep!! It's 2:30 am in my part of the world.

I just thought I would post the link in case anyone wants to take a look at it and give me feedback. I would love to hear any opinions as I am planning to make the purchase next week!

Thanks again!!

Both look good but I prefer the ACA. I think the hearts image might be slightly tilted, check with WF concerning that, also a couple of the arrow shafts look to be very slightly shorter than others on both ASET and IS images, just mention that to WF.

 

[stone-cold11]

Ditto.

Also the ASET of the ES looks tilted too. IS has a slight leakage in the 9 o'clock position, but probably not noticeable in real life. But overall, prefer the ACA in this case. Just depends on what is your priority.

Thanks so much to you both!

I only wish I could understand exactly what you are telling me!!

Lorelei, you mentioned some of the arrow shafts being slightly shorter on the ACA image. Would that affect the performance of the diamond when just looking at it with the naked eye?

I should say that I''m not really concerned with things that won''t be visible to the naked eye. I just want the best looking diamond I can get for about $4,000-5,000.

I saw this cheat sheet on an earlier post. (They referred to it as Lorelei''s cheetsheet!) I looked at the two stones and the ACA is a bit out of the range on table %. The Ideal Cut is a bit out of the range in depth % and crown angle. Should that be any concern?


depth - 60 - 62% -
table - 54- 57%
crown angle - 34- 35 degrees
pavilion angle - 40.6- 41 degrees
girdle - avoid extremes, look for thin to slightly thick, thin to medium etc
polish and symmetry - very good and above

If you both tell me that the ACA is a good diamond that you think will perform well, I can take your word on it as you knows lots more than I do! I am a little nervous though about buying a SI1 diamond. On the 40x magnification I saw some inclusions but nothing too horrible in my opinion. Do you have an opinion regarding the clarity?

Thanks so much!

Lorelei, you mentioned some of the arrow shafts being slightly shorter on the ACA image. Would that affect the performance of the diamond when just looking at it with the naked eye? I don't think so, its a great diamond and I could be nitpicking to be fair, just mention to WF about those arrows and see what they say. The hearts image could be tilted or not and the slight difference in a couple of the arrow lengths is visible in a couple of the images, I can see it in ASET, Idealscope so I don't think its the images themselves as this would not show in all of them if it was a result of tilting, more likely the diamond itself, but it really isn't anything to worry about, just something I can see after looking at hundreds of ACA images. Its still a great diamond and will be beautiful, and this very minor difference I can see would not be visible with the naked eye - bear in mind the actual size of the diamond is slightly smaller than a pencil eraser!

I saw this cheat sheet on an earlier post. (They referred to it as Lorelei's cheetsheet!) I looked at the two stones and the ACA is a bit out of the range on table %. Its fine, table size is perfect and nothing to worry about.

The Ideal Cut is a bit out of the range in depth % and crown angle. Should that be any concern? I don't think so, the depth is a hair deeper than I personally prefer but its still a good diamond and this type of stone which is around fiery ideal cut range sometimes show extra depths. Crown angle is fine, steeper are often a feature of the fiery ideal cut along with a smaller table. The cheat sheet itself is intended to be a guide and often you can find diamonds which don't quite match up which are perfectly fine, it isn't possible to list all the various proportion configurations which could work so the cheat sheet is a starting point.

depth - 60 - 62% -
table - 54- 57%
crown angle - 34- 35 degrees
pavilion angle - 40.6- 41 degrees
girdle - avoid extremes, look for thin to slightly thick, thin to medium etc
polish and symmetry - very good and above

I am a little nervous though about buying a SI1 diamond. On the 40x magnification I saw some inclusions but nothing too horrible in my opinion. Do you have an opinion regarding the clarity? The ACA looks good as far as I can tell, so does the other diamond. Both are of different types though, the ACA's are known for visual balance, the other diamond is geared more towards fire in some lighting, in other words will show more coloured light. It depends on what you are looking for, personally for the best balance I would lean towards the ACA but it depends on your preferences. SI1 clarity can be an excellent choice if verified eyeclean, if WF have checked this for you and told you it is eyeclean to your standards then thats fine. If you are seriously interested in the ACA I would put it on hold as soon as you can....

Thanks so much!

The stone is tilted when the IS image is taken so there is a slight difference in length of the arrow shafts, It is not a fault in the cutting of the stone, so don't worry about that.

Cheat sheet is just a safe rough number guide, smack in the middle of the tolkowsky ideal cut proportion for those sorting out a large number of stones or just buying blind with only the numbers to work with, it is not the only proportions that can work. The IS/ASET image is much more important, once you get pass the weeding stage.

Clarity only the vendor with the stone in hand can say if the stone is eye-clean or not, so we can't really say since we do not have the stone.

I got so busy the other day that I never got back on to thank both of you for your input! Your advice was really helpful. I am about to pull the trigger on the ACA.

Stonecold and Lorelei, I''ve noticed that you help everybody!! How wonderful to have you both here to help out newbies like me.

Thanks again!!

 

[stone-cold11]

no prob, glad to help.

Good luck.
