Of the IGI certs 26.4% of the 1000 least expensive diamonds have a depth greater than 66% and a whopping 17% have a total depth greater than 67%.Date: 8/15/2008 3:40:15 PM

using a pretend 1 to 10 scale of diamond beauty...
The average rb on the market in my area is a 6 and the best rb a 10
The average princess on the market in my area is a 3 and the best a 10
The difference between average and best is much wider in princess cuts.
In my opinion and according to my observations.
I''d add that if you walk into a discount-diamond outlet in any major city the low end of the round range drops off.
DiaGem, here is some actual data for you. I searched Rap for round brilliants, D-K, 0.90-1.10 ct, sorted by best available price. Those examples are what you might expect to find in “discount” consumer markets. I only looked at depth, so it''s far from an actual study, but I hope it interests you.
Note that IGI and EGL have different report formats; many of which give no indication of cut quality, like the examples posted above.
IGI-graded
Of the lowest-priced 1000 round brilliants returned
617 have depth >63%
397 >65%
264 >66%
170 >67%
(70 = no depth reported or incorrectly classified)
EGL-graded (all labs)
Of the lowest-priced 1000 round brilliants returned
545 have depth >63%
282 >65%
184 >66%
124 >67%
(30 = no depth reported or incorrectly classified)
GIA-graded
Of the lowest-priced 1000 round brilliants returned
671 have depth >63%... Post-2006 reports show a cut grade of VG or lower
(49 = no depth reported or incorrectly classified)
AGS-graded
620 round brilliants listed
65 have depth >63%... None of them received AGS0
(10 = no depth reported or incorrectly classified)
I believe new shoppers in commercial markets, as well as those looking online, are more protected by seeking reports with a reputable cut quality assessment.
Even better advice, tailored to each person: Choose the jeweler before you choose the stone. Choosing an AGS member is usually a good choice. Choosing a dealer in AGSL goods is another good choice. There are others of course. The lab report, no matter what lab issued it, is support for the confidence you are placing in your jeweler, not a substitute for it. The one who is calling it ''ideal'' is the jeweler just as they are the one who chose what lab and what definition to use.

Serg,
Please read the edited part of my post. I know that it doesn't change things very much. As a consumer, I honestly don't have enough confidence in my own ability to make an educated choice in a diamond without some very clear parameters. What is a clear parameter to me is very different than to you. You already have this knowledge and I'm just learning. I have enjoyed our discussion. I am open to new information.
re:ETA: I didn't see the part of the post that said that my eyes preferred the second diamond!! In that case, I would be conflicted. I would probably go home and think it over and not make a decision on the spot. It would make my choice more difficult. I hope I would choose the diamond my eyes prefer, but it would be a close call.
Marian,
Fine. I will try again
Do you have chance do it if you firstly ask reports?( and then see diamonds)
Do you have any chance now to find what your eyes could prefer except AGS0 ?
Do you enjoy what you have choice only between ASG0 round and ASG0 princess ?

Serg,
If I see the reports first, I might be biased toward the AGS diamonds.
If I don''t see the reports first, I have the best opportunity of making an unbiased choice--provided I trust the vendor.
I would be interested in having more choices than a round or a princess.
If there were no AGS or GIA, who would provide oversight? This is one of my concerns. Is there an alternative?

Wink there is a difference...
Lets fast forward 3 years and say I get very lucky and have some of my better designs available for sale.
I am not so much competing for the mall IGI buyer I''m competing for the sales to your type of customer vs other cuts and brands.
If they are all convinced anything but AGS0 is junk then where am I?
Where are you because they are a perfect opportunity to sell beyond the engagement market.
In my opinion the average Lady has too few gemstones and diamonds :}
I want to give them a reason to change that.
Honestly the typical mall store diamond buyer would have 0 interest in them.
The only way they would is if I took the money and ran and they were for sale in the mall stores.
The customers I would target are your customers(and Jon''s and Todd''s). (Which is why if it ever happens I''m going to hit you and them up to carry them)
Lets find a way to weed out the bad cuts in consumer mind share without damaging the rest of the excellent cuts.

I cant yet guarantee I can do so at this size but lets say I can make these measurements and yield level beautiful: (I have a few designs that might very well do this but they aren''t well enough researched to say for sure)
1.20 G SI1 66% 61% GIA - no gd gd 6.69-6.61x4.39
$5557
lets set the price of the same diameter AGS0 as the max price:
1.101 G SI1 1.6-EX
ex-ex-ex-vg 0 61.9% 57% 34.8° 40.8° thn-med f id id no 6.58-6.67x4.08 AGS $6533*
Lets say it comes back si2 because AGS may be a little stricter on clarity:
1.084 G SI2 1.5-EX
ex-ex-ex-vg 0
H&A
ACA 61.5% 57% 34.8° 40.8° thn-med f id id no 6.58-6.65x4.05 AGS $5819
See the power? A beautiful 1.20ct stone I can sell for the same or less than the same diameter but lighter AGS0 and make a nice profit.
Everyone wins from the cutter, rough producer, and consumers.
There would of course be some rough close to a magic numbder this would not work with.
This is the magic of unrestrained research and cutting :}
And that's great, as he is cutting fancies, correct? I do believe he said in here he doesn't cut rounds, which is part of what we have been talking about. But let's say he was cutting a round. You said he uses his experience and a lot of "that looks right". Which implies there are points where he would think something doesn't look right. But those "don't look right" stones are out in the world being sold every day, and they're not pretty. That's my point.Date: 8/16/2008 1:47:56 PM

I totally get that there can be diamonds with uncoventional numbers that can be beautiful. It's the (imo) preposterous statement that every single diamond, regardless of cut, is going to be beautiful. That is what I (and I imagine almost everyone else here) have a problem with.
To understand DiaGem you have to know his work.
Unfortunately a lot of it cant be posted in public because:
1: that market demands privacy.
2: the risk of theft of the designs.
What I do in DC with unconventional designs he does in diamond at the wheel using experience and a lot of 'that looks right' to make beautiful diamonds.

I cant believe this thread has been going on for so long!!! LOL
When you guys come up with a system for grading cushions (much more valuable in my opinion) let me know. Cushions are the most confusing and yet bluenile and others have ''ideal'', ''signature'' on many of their selections.
I would pay extra for a service to ''pre-screen'' cushion cuts for me.
Thanks
In same time Average LR is to small( main reason is big Girdle ration what do difficult LR optimization. For square Cushion task is much more easy)

Whoa, I have waded through all nine pages of this thread, and just have one question... where''s the hair-pulling emoticon when you need it???!!
OK, seriously... FWIW, I liked the Podcast. As a consumer, I understand the audience John was targeting, and the message he was making. For us PSers, it''s hard to believe, I know,but not everyone wants to immerse themselves into knowing and learning about (or agonizing over!) diamonds. For a person like this, buying an AGS-0 stone is simply one easy way to make it a relatively no-brainer type of experience, while still ending up with a beautiful diamond.
And, oh yeah, one more thing... add me to the masses... I am definitely a ''noticer of SIZE and SPARKLE first!'' kind of a girl!!! Oh yeah, babeeeeeee!
I think there is a misconception here. The lead graphic at that link cites "mass-production" of ideals as a prime influence (see below) but this is not the case.Date: 8/16/2008 9:32:42 PM

There is lot of rough that will not cut into an ideal cut in today''s market for many reasons.
Isn''t it about time someone said hey we can do better than cutting them like we always have and selling them to unknowing consumers who mistakenly trust the wrong people?
