Hello All,

It’s been a while since I’ve been on this forum. Life and work seem to keep me busy. In any case, I’m hoping to enlist your wonderful expertise in critiquing the following diamond images. Please note that I’ve already searched high and low on PriceScope and a multitude of other online databases for the perfect stone and came up with a very short list since my criteria was very narrow. Now I’m utilizing a phenomenal concierge service to source a comparable GIAXXX diamond that would meet AGS000 marks.

To give you an idea, I personally vetted GIA certificates for the following specs:
Excellent cut, symmetry, and polish
Table: 54%-57% (prefer 55% for thickness of arrows)
Depth: 60.5%-62.3% (ideally <61.3-61.7)
Pavilion angle: 40.6-40.8 (ideally 40.8)
Pavilion %: 43%
Crown angle: 34-35.5 (ideally 34.4-34.6)
Crown %: 14.7%-15.5%
Lower Girdle Half Length: 75%-78% (GIA rounds to either 75 or 80 so I leaned towards 80)
Star Facet Length: 45%-51%
Girdle: thin to slightly thick (ideally 2.5%-3.5%)
Fluorescence: Medium

Upon finding potential super-ideal candidates, I asked for ASET/ideal scope photos with goal of:
minimal signs of crown and pavilion painting and digging per ASET images
Symmetric hearts with minimal cleaving

That being said, here’s the diamond I’ve reserved and before I bite the bullet, I’d like to run it by you all.

.7ct, table 56%, depth 62%, and crown angle of 35.5 paired with pavilion angle of 40.6. HCA score is 1.3.

In both the ASET and arrows images, I’m noticing clustering around the center. Technically, I’m not sure what that implies.

Your help is much appreciated!

On first look at the ASET I would agree with @HappyNewLife. BUT I don't believe that this necessarily means it won't be great. The numbers and HCA (number and graph) are promising. Could you perhaps ask the vendor for a video, ideally in a couple of different lighting situations. This may help know the sparkle potential more.

I feel like there could be some light leakage on the table, but I'll let others chime in.

Thank you for your feedback and for sharing the link. I was initially leaning towards slightly better than “above average”, but not quite excellent. Waiting on video from different lighting sources.

I’ve also asked the jeweler to see if can source another promising diamond, but since many of these (based on my desired specs) are virtual inventory located overseas, may increase final purchase price to cover shipping costs, time, and resources.

Learning that although branded super-ideal AGS000 cost more, the consumer can vet through the supplied images with ease (assuming vendor provides ASET, ideal, and/or H&A). On the other hand, non-branded stones may be cheaper up front, but the vetting process can tack on additional costs/fees. Basically, Nothing in life is free.

Well said. :clap: :clap: :clap:

At the end of the day, it's a risk equation. Branded super ideals are less risky and more hassle free. Time is our most valuable asset, and many times worth the small difference for guaranteed performance.

Plus, people sometimes forget that cutting to precision levels takes more time which costs more money. Having fancy equipment to take advanced images again takes more time and money. Base line cost will be more so even if you add the same % profit, the price will be higher than a stone without those additional cost premiums.

Of course, Joe Consumer doesn't care. His worry is he has $5,000 to spend on the biggest, whitest and most sparkly diamond possible. Which kind of gets you into the chicken or egg debate.

Unfortunately, neither HPD/CBI, BG, WF, JA, VC, nor Enchanted (vendor’s that supply ASET/ideal) had any viable options in the $2500-$3000, .64-.75ct range with medium fluorescence :cry2:. That’s why I expanded my search to virtual inventory.

Karl, thank you for the confidence boost. I would like to get the diamond I buy AGS certified (willing to pay for certification), if it isn’t already. If I were to go with this one, would it achieve an AGS ideal grade based on the images provided per your professional expertise?

It has an excellent optical symmetry and very nice arrow patterns. The clustering combined with the minor leakage (crown of 35 would've been better) may show as darker center but it could also act as contrast and the diamond could still be a lovely performer. Purchase this if there's meaningful savings against better proportioned super ideals.

I would not go as far as say which grade it would get but it has the potential for ags0.
I honestly would not bother getting a AGS report on a stone that has a GIA report.

Not with that ASET it wont.
Its hard when its red and green but remember anything the same brightness as the center is not significant leakage.

Nope.
It passes ASET and h&a tests.
That vendor removes the blue top from the ASET scope for photos.
AGS allows this with a white background.

ah ok, good to know. disregard!

35 crown paired with 30.6 or 30.8?

35 max (if not rounded up) for 40.6. Past 35 with that combo, it's generally a weaker H&A. Look at the link I've shared earlier - it'll have a table for you to look up.

@Karl_K, just to clarify, I think I read a post before and you mentioned when backlighting is strong like what appears here you have to look at the cutlet and find the lightest color to determine and compare that to the lightest color in the "ring" to determine if true leakage or not.

Correct?

That said, I believe the light green speck I circled below is the lightest and I also circled a few of the lightest red pieces in that ring. I'd think those are about the same shade/intensity. Those not circled would be better.

All this meaning there is no leakage.

Your list is relatively shorter compared to mine. I looked at thousands of diamonds in a few months span and I have over 300 line items with details in my excel doc :loopy:

You actually did really good finding that stone considering it's not a branded ideal.

I have to give credit where it’s due. The jeweler I’m working with through the concierge service found this stone and he did a fantastic job considering my tight parameters.

Medium fluorescence narrowed the search down significantly in addition to applying the advanced filters

Lol you made me count - mine is 20 columns, including my long notes.
I was helll bent on finding stones with particular combo that superideal vendors don't offer, so the search was excruciating. Though I found what I wanted and I love em!

No meaningful leakage and they are where they are expected.
I forget the approximate number but it's like 1 or 2%, not significant.
Also remember that ASET has very low virtual facet resolution.
The large areas of red are actually made up of 100s to 1000s of virtual facets.
Only a few of those thousands actually leaking can lighten the red.
Anyway,,,,,
The pattern varies by the crown, pavilion, table, and lower combination.
No front lighting, back lighting only.

Upload Excel file to Google Sheets (free) and you can post a link. ;)2

Sheets isn't as powerful as Excel so if you got fancy some features may need tweaked when you convert.

Yup, the Google sheet is where I eventually ended up so that I could access the info through cell and Chromebook. Actual line items 517! lol, lots of private comments.

Damn, that's alot of data entry. Did you get a main CSV dump from somewhere to get you going? Or manually enter it all?

Thinking I'd be using a suck up intern to do mine, lol.

I recently saw an AGS0 stone that was brought out by a local store as an example of a "perfect cut" by his definition. I was looking at the ASET real-life and noticed the pale pink center, but my e-ring stone was solid red all the way in comparison. I would take solid red all the way, although the chances are you'll hardly notice the difference naked eye.
My stone was definitely sparkier and brighter, but I'm biased. :P2

Manual, and only after seeing the photos and videos. Yep, it was obsessive...
