Another GIA help thread:-)

[krusty900]

Just wondering if I could have people’s thoughts on this stone?

Crown angle is 36, but Pavillion is 40.6(which I think works) hca scores 1.3.

Just wondering how something like this would fair compared to a superideal to the untrained/naieve/gf does not care eye?

Thanks

Woops. I just realised I had already asked about this one on another thread
I guess I’m still wondering if the average person could tell the difference between this and a superideal in real life?

Probably not right away. Maybe with time they will be able to tell. Nonetheless, the combo works and some people even prefer it as you are expected to see more fire (colored flashes). Scintillation (white sparkle) might be reduced, but again, I am not sure how noticeable that would be to the untrained eye. Beautiful specs otherwise. What is the price tag of the stone? Have you purchased it already?

 

[krusty900]

Thanks for the reply @SimoneDi have not purchased. I have changed mind on setting from whiteflash and they don’t have any others I fancy so just looking everywhere at the minute.

So you are in the market for both ring and setting? What is the total budget and what kind of setting did you like?

 

[krusty900]

Total budget is 10k aus, so 6.5us for ring and diamond (then 10% tax)
Had this in mind originally due to price and narrowness, but have since ruled out to weird looking prongs/height of them.

This is the most recent contender and probably only other option from whiteflash that I like. But more expensive.
https://www.whiteflash.com/engageme...fany-style-solitaire-engagement-ring-1416.htm

Was wondering about gia stone that I posted above again as it’s in Australia and with a platinum solitaire ring will cost my budget, could even pay with no interest if I chose.

I was set on superideal, but In reality don’t think either of us would know the difference!

 

[Kaycee2018]

OP, I had the same dilemma when I upgraded earlier this year (paying the premium for super ideal vs. vetting GIA diamonds to get as close to super ideal specs as possible). Ultimately, I went with a GIA diamond with specs very similar to the one you first linked above (GIA Rep. #5181946889). Mine has a 36 deg. CA, 40.6 deg. PA, 61.9 depth and most of the other specs are identical. I am beyond pleased with my diamond...even the independent appraiser who did the appraisal on it and my local jeweler who recently cleaned it both commented on what a beautiful diamond it is.

Granted I gave up the "security" of simply buying a super ideal cut (and the very generous upgrades that some of the super ideal vendors offer), but the price was significantly less than a super ideal and although I purchased sight unseen, the retailer had a good return policy so there was no risk really. And quite honestly, I cannot see much, if any, difference between super ideals vs. GIA ExExEx diamonds with specs close to super ideal (truly well cut GIA ExExEx)...not enough of a difference for me to pay the premium anyway. I can however see a difference difference between GIA diamonds with specs similar to super ideals vs. poorly cut GIA ExExEx diamonds. Don't get me wrong, I understand why some people love and push super ideals...they are basically take the guesswork out of finding a diamonds with the best specs and many super ideal vendors have pretty amazing upgrade policies. Also, GIA's rounding makes it more difficult to vet diamonds on specs alone and seeing how they perform IRL is a better test.

if you decide against going with a super ideal, I would definitely suggest staying as close to super ideal specs as possibly and listening to the expert advise offered here. These folks know diamonds! LOL You say this diamond is in Australia...have you seen it IRL or does the retailer have a generous return policy where you can purchase and return if it fails to meet your expectations? Seeing it IRL will help you make your decision. GL!

So if you don't want to spend the premium on a super ideal, why not find a GIA XXX that has more ideal proportions so you don't have to worry about tricking your girl? Personally I think you are on the fringe and because of whacky GIA rounding & averaging I would try to find a different stone.

What makes this stone "the one"?

Some reading for you:
https://www.prosumerdiamonds.com/crown-angle/

Steep-end of the Ideal Crown Angle
For a fixed table percentage, a steeper crown means that the crown is higher and the crown facets are larger. This means more incident light rays can fall onto the prism-like crowns generating more dispersion so the diamond will have more fire.

The trade-off of having a steeper crown angles is that the lower girdles tend to begin leaking light once you go over a 35-degree crown even if you have a 40.8-degree pavilion. This happens because the lower girdle angles are dependent on the pavilion angle and the lower girdle length and a steeper pavilion causes even steeper lower girdle facets.

Even with a 40.5-degree pavilion and shallow lower girdles, you really do not want the crown angle to be over 35.5 degrees.

According to standard assessments, a steep crown angle will disperse light away from the observer in the assessment. This means that although you may not be able to see the diamond’s fire, other people looking from an angle might think it has a lot of fire. Also, a higher crown means that a lot of the diamond’s weight goes into the crown height rather than the width and hence reduces its spread.

If we are talking about a 34.5/41 CA/PA combination vs a 34/41 CA/PA, my personal preference is the 34.5/41. For me, the trade-off of decreased light return is more than made up for in the increase in fire. This is because weaker light return under the table can have a positive effect in terms of the contrast of the diamond.

You will even find that some super-ideal diamonds have crowns that are closer to 34.8-degrees. This is done to improve the fire in the diamond even further and is only something that should be done in a precision cut diamond. This is why super-ideals seem to contradict the general idea that there should be an inverse relationship between the crown and the pavilion angles.

 

[diamondseeker2006]

With a crown angle above 35.5, I would have to have an ASET image to determine if there is leakage. Many 36s may be fine, but since GIA rounds numbers, your measurements are not exact.

Some potential alternates. Give us your budget, color, clarity and carat requirements and I will try to find a few more.

Another good bang for the buck. Slightly smaller by 0.10mm but difference is so minimal, you won't be able to discern the difference with the naked eye.

[Kaycee2018]

OP, correct me if I am wrong, but I believe the diamond you linked above (GIA Rep. #5181946889) is the same diamond linked in your previous post (https://www.pricescope.com/community/threads/another-aussie-hello.242795/), which includes ideal scope images, etc.?

Edited to add the intent of my response was related to the following from OP:
"I guess I’m still wondering if the average person could tell the difference between this and a superideal in real life?"

 

[krusty900]

Wow thanks so much for the replies such a friendly place
@Kaycee2018, yep you found my previous request, purely stumbled back across it looking for a setting as was not having much luck with the superideal vendours and a setting I liked .
Also diamond was in Australia as you found, can not see in person but could buy and return and then get it set Etc, was just thinking this was easier than buying from overseas.

@sledge you’re truly a legend, nothing makes this ‘the one’ as above just stumbled back across it again and was wondered how it would fair IRL as It could be a potentially easier purchase and in budget. thanks for those links. The whiteflash ones I had been looking at, but not really loving any settings from there, so that’s why was looking elsewhere.

@diamondseeker2006 the vendour posts this

Thanks again for all the help/thoughts.

 

[sledge]

Thank you for the kind words @krusty900. I knew this seemed familiar but didn't have the time to do the digging. Thank you @Kaycee2018 for finding the old thread, and refreshing my memory. I had said quite a lot in that thread, lol.

Oddly enough, even though I subscribe to threads I post on, they seem to not always update me (even when they previously did). I am not certain why. Anyone know the reasoning? I used to look through recent posts, but that list is quite considerable now as I talk too much.

Hey there I saw you in my thread. My diamond had larger crown angle than yours at 36.5 with a 40.6 pavilion like yours. Had a 2.3 HCA. Yours should sparkle even better than mine!

 

[LBeezy34]

Are you in Melbourne @krusty900?

 

[Katya DXB]

Hey @krusty900
I was just comparing a GIA XXX (although the proportions are not exactly the same) side by side with a superideal the other day, you may find it interesting
https://www.pricescope.com/communit...-52-h-si1-cbi-review-and-lots-of-pics.243371/

While I can see a difference between the two stones, I absolutely adore my XXX and am very happy with her performance. It took me a while to decide to purchase a superideal, and one of the reasons was that I wanted to be 100% sure I will be able to fully appreciate her. Hope that makes sense

 

[krusty900]

@LBeezy34 , tassie, not Melbs. Not much to look at down here to compare.

Thanks @Katya DXB that is great. Probably confuses me further
I’ll have a another look over the weekend.

@krusty900 it's not that far if you ever do go see Aaron from Diamond Story. He got me my James Allen stone (felt more confident with superzoom) so much cheaper than on the site. He packages custom band setting and import tax to bring it to Australia at such a cheap rate! In total it ended up being only $580 more than the JA stone only listing!
