Hi, please help me decide between these two amazing stones. I’m pulling my hair out at how difficult it is to commit to either one.

Adiamor $5100 [the one with thicker setting; and smaller of course]
GCAL 8X
2.82ct
9.12x9.14x5.55
60.80
57%
34.5/40.6
HCA 0.6

Frank Darling $7890
GIA
3.34ct
9.53x9.57x5.90
61.8
58%
34.5/40.8
HCA 1.3

I already had the GCAL set into a platinum setting. The stone is absolutely beautiful, but it throws more fire than moissanite and I don’t know how to handle it especially under grocery store lighting. It blinds everyone briefly giving it a glimpse. One big problem I find is that the ring can look quite dark under certain lighting. When I first picked it up in person from Adiamor, I immediately noticed how dark the stone looked in my car. I thought it could be from the setting prongs being too bulky and also covering up the culet. Is it possibly that the stone can regain some brightness if I change to a more dainty setting?
GCAL 8X 2.82ct
Pros: cheaper, the light performance has been vetted by the lab, the hearts and arrows and symmetry are near PERFECTION, GCAL prices are increasing steeply! Adiamor has hiked an average of $3-4k on all Gcal stones this week.
Cons: stone appearing darker, lower HCA score of 0.6, too much rainbow-disco-ball-fire, potential light obstruction either from the proportions or too much prong coverage.

GIA 3.34ct
Pros: larger, higher HCA score of 1.3, looks brighter and throws a more effervescent, powdery and ethereal sparkle unlike the insanely bold and sharp fire of the GCAL, has the perfect proportions (34.5/40.8), less but adequate fire/disco ball.
Cons: more expensive, light performance has not been vetted, GIA rounding could be dodgy, the hearts and arrows are much further from perfect (steep clefts on the hearts, splintery and asymmetric arrows) and overall symmetry is questionable, spread is less ideal than GCAL.

Do you think the cut quality is more important than the proportions or vice versa? At what point does one reasonably outweigh the other? Please help! Thank you

If it were me, I would return the GCAL stone because it bothers you when it goes dark, and the type of fire is not exactly what you're looking for. Light comes in from the top and goes out of the top, so the prongs should not be causing the darkness.

I can't say definitively whether cut quality trumps proportions because even though the 2.82's cut quality is nearly perfect, its performance sometimes bothers you.

Can we help you find a more precisely cut 3.3ct?

This looks pretty tightly cut to my eyes, for example.


That one does look very nice but I want to stay away from 40.6 since my experience with the GCAL stone. I actually just bought another stone you recommended on a different thread. Hopefully this one checks out all good because I threw in the towel and put it on a setting. I am finished with diamonds by now lol

By the way, can I accurately check ASET on a stone that has already been set?
Thanks!

Yes, you sure can! It will take some trial and error to get the diamond lined up properly with the ASET scope, but no problem with it being already set.

Hello and welcome to PriceScope, tweety09091004!

Do you have the grading report number for your GCAL diamond?

Super ideals will go dark in direct sunlight.


Yes, I've heard that. The reason why I'm confused with the stone is that it almost constantly carries a dull, grayish hue that almost looks as if it's radiating from deep within, behind all the white light and chunky fire that it throws. Even in LED spot lighting it will look more gray and overcast than the GIA stone, despite how sparkly and brilliant it is. It certainly goes dark in direct sunlight and in the car but that doesn't bother me as much as this constant grayish hue that makes it look darker.
Idk, maybe I'm still confusing this with the stone's potentially super ideal characteristic?

Good to know ASET can be checked! Thank you

Here is the GCAL report:

Thank you...I wanted to check and see if there was a potential for stria causing light scattering (blurry/hazy appearance) or birifrengence (double refraction like Moissanite).

Since you've had the opportunity to view both diamonds and your eyes, mind, and heart prefer the diamond graded by GIA, then the choice is an easy one!

I see, I don't think the stone has much visible stria, at least not any that I can detect at 30x and 60x. Well, I just bought a 3rd stone with a setting as per @Kim N 's recommendation on another thread. Hopefully it'll put my decision paralysis to an end..... :mrgreen2:

Wonderful, I really liked that 3.56! I was only searching for GCAL or GIA on your thread, so that's why I didn't post any IGI stones here. Looking forward to hearing what you think of it!

Wow there is quite a visual difference! The GIA graded diamond does appear to have an advantage with being more...luminous (for lack of a better term)...between these two particular diamonds!

Agreed! I'm very surprised to see a GCAL 8x stone looking so grey.

I actually have this "dark grey" issue with my new OEC too. When I'm in direct sun and in my car and LED lights. My old OEC that was "L" colored and cut 'poorly' didn't do that. It's hard to describe and hard to pinpoint what 'exactly' i don't like but it sounds like it's the same thing you have. I just dont understand how or why when it's supposed to be cut 'perfect'.

I’ll definitely share it in another post once I receive the ring. Thank you for the help!

Interesting that you had a similar experience with yours. Now that I think more of it, it might also be related to the CVD tint as well as the diamond proportion.

So, the ring is here. I can say I like the stone very much, but not the setting. Look at the overall quality of the prong work….:cry2:
One of the prongs is not even touching on the stone.

I contacted Ritani a few times now to get this resolved but no replies yet. Poor communication is what my experience was with them and I’m guessing it’s going to take some more time and effort to have them reach out to me.

Sorry to hear about the setting quality. I hope they can fix it quickly for you. How does the stone compare to the two you had before?

I hope so too.

The stone is very pretty and to me, looks quite like a mined diamond compared to the previous ones. I think it’s partly because it doesn’t scintillate or throw fire as much as the previous stones for some reason and I’m trying to figure out why, since the cut, ASET, HCA, and proportions are all good. Not that I’m looking for the disco ball look again but this makes me wonder whether it’s a quality issue or something else.

It sometimes also looks very filmy under low light settings, which also happened with the previous stones but to a lesser degree. I did notice some graining in the magnified 360 view before purchasing it but so far I haven’t been able to find a CVD without this varying degrees of pervasive spreading of striae so I was willing to overlook that. But perhaps that’s what’s contributing to this filmy look at certain angles? Idk.

This now raises a question whether to switch to a HPHT or not, for the look of crystal clear facets…I feel bad for costing these companies logistics fees by returning items but my heart just hasn’t settled into any one stone so far :oops2::cry2:

Send it back...if it bothers you now, then it will always be a bother. Plenty, plenty, plenty of other diamonds to choose from. Trial and error...and at least you're not stuck with it forever like you could be from so many other sellers that would give you no full return policy.

I agree with DejaWiz, no reason to keep a stone you're not in love with. Can you give the stone a good scrub with a toothbrush and post some more photos? It looks a little odd in this last set of pics.

I see what you mean about filminess- very strange! I agree the setting looks pretty poorly done as well :( give it a little time but if you don’t love it def send it back. It’s a big purchase and you should love it!

Gave it a good wash. Sorry for uploading too many same looking pics but just to give you an idea :)

And yes, you guys are right… I’m not sure if this filmy look is normal or not, but I may be better off returning it.

The filminess is so peculiar. I never would have expected it in a VS1, and it doesn't show in the 360 video. Definitely return it and go for a new one.

I second this. A VS1 with haziness under indirect lighting...perplexing, to say the least. I've never ever seen that occur outside of very cloudy diamonds in the SI1 or lower clarity grades.
