Hi everyone. First time posting and I''d like to thank eveyone who posts here as you have helped me very much in my search for the right diamond. i''m lookiing for a princess cut diamond and have been given some conflicting info as to what determines a good cut. The ring I am looking at is nearly a perfect square (which is important to my gf) with the following stats:

GIA certifiied
1.22 Carats
D Color
SI1 Clarity
5.78 x 5.74 x 4.16 mm
Table 68%
Depth 72.5%
Polish: Excellent
Symmetry: Very Good

Setting: 14K White Gold Cathedral Bridge

Price quote: $6400

This table and depth percentages fits within the limited info I have found for ideally cut princesses,: but i''d like to hear other opinions. I have also been told by one jewler that table/depth should be very close to one another with a princess and that is more important than the actual percentage. Is there any truth to that? Thanks in advance.

Confused Chris
 
We can't comment on a princess cut's performance with just numbers. Need an ASET/IS pic to work with.

Go with these number, but please note that even when all the numbers are within the ideal cut, the stone can still not perform ideally.
 
Thanks.

I not real familiar with ASET/IN reports beyond knowing they measure the reflection of light. Is there a report that comes with a ASET/IN analysis or am I on my own to judge it with my eyes.

Chris
 
It is not a report format but a visualizing tool. Link on how to use the tool with accompanying reference chart.

You can buy the tool online.
 
Thanks stone-cold.

That was the chart I using.

Do dealers usually carry an IS and ASET or am I stuck spending a few hundred?

Chris
 
Are you fix on getting the stone from the store or are you open to buying online?

If the former, ask your store for AGS0 cut graded princess. That is a safe bet on cut performance.

If later, what are the specs you are looking at and your budget and we can help you find something. The vendors we like to recommend will have these images.

Some stores have them, some dis them as gimmicks.

Also a D color carries a very high premium, normally one would not be able to notice any color down to G/H. Something to think about if you want to maximize your budget.
 
I'm open to buying online but would prefer a something I could see first. The D color is not a necessity, but i'd like to stay at least a G. Clarity at least SI1.

Chris
 
Since you said you were open to buying online...

If you're willing to give I color a try (I promise it's not yellow; my princess is an I that looks like an F due to the cut quality)...

This one is a tad smaller than your original choice, but it's F color and a more perfect square:

Here's a 1.14 G/VS1, but the cut quality isn't quite as tight as the first 2 I posted:

Also not quite as tight of an ASET, and a tad smaller:
http://www.whiteflash.com/princess/Princess-cut-diamond-49250.htm#

Despite the I color, I really think that's the best choice of all of these, and the color really saves you a pretty penny. If I remember correctly, the 1.21 I/VS2 is the diamond on the far right in this video. I bet you can't tell the difference in color (I know I can't!).

Ideal Scopes or ASET are not a few hundred dollars. Since you are buying a princess, an ASET is more useful than an IS.

It''s 50. https://products.gemappraisers.com/pc-35-1-ags-aset-scope.aspx

Where are you located? You may be local to a jeweler who also has online presence.

Ditto. Also if you are open to buying online, have a look at J star''s selections, and if you want to buy from a jeweller Julie has linked the ASET tool for you which could be extremely useful.
 
Thank you everone who have replied. To answer some of your questions. I live in central New Jersey so I do have access to the diamond district in NY. I am by no means locked into the D color just happened that the diamond my girlfriend and I saw and liked the most was a D. I do have some concerns about dropping to an I color although the one on Good Old Gold is very impressive and that site seems to be highly regarded on these boards. I could get out to their store in Long Island to see in person. Thanks for all the info on the ASET.

It seems with princess cut diamonds that AGS supplies more info than GIA in regards to cut. Is this correct? Should I be focusing on AGS certs. if cut is most important to me?

If you can, then I would really make the effort to get out to GOG and view in person.

AGS are the only lab at this time to grade Princess, personally I prefer not to assume that AGS0 is the only way to get a well cut diamond, especially if you are working with a trusted vendor who has in house Princess with all the cut evaluation done for you, so I would say to keep your options open and consider diamonds from both labs if you have the cut analysis for either lab's Princess such as ASET images and detailed photographs. I know it is easy to get that impression here that AGS0 is the only way to go, but in my opinion an open mind is beneficial, especially if you have an experienced and trusted vendor to assist you and we are not best serving new posters if we don't point out all the options available to them.

You could give Jon at GOG a call to make an appointment and he should be able to have some diamonds to show you that might suit you.
 
Thanks jstar and lorelei. I will be travelling to Good Gold Gold tomorrow to meet with Jonathan. I also plan on stopping in the NY diamond district on the way back to Jersey. If anyone has any specific jewlers they would recommend there I would appreciate it. I am aware James Allen has a warehouse there with by appointment only viewing. I have seen them recommended in other posts. Any others would be helpful. Thnaks in advance.

You are very welcome Chris!

Firstly I wanted to make you aware that right near GOG is a fantastic pizza place from what I understand....

Once you are back in NYC, you could also see Mark at www.engagementringsdirect.com to see what he can show you, I think you might need to make an appointment, Mark is on 47th St I believe in the DD. JA I think you might need to make an appointment too.
 
You''re so lucky to be local to GOG! I''ve always wanted to see their inventory.

You''re right that AGS is the only lab that offers cut information for princesses, but Lorelei brings up a good point about non-AGS0 princesses also having potential. The way I see it...if you want an easy way to weed out poor performers, stick with AGS0. This is especially helpful for buying online, sight unseen. If you want to broaden your options, look at other labs as well, but keep in mind that there may be a mixed bag of great cuts and not-so-great ones. You''ll have to use your eyes (and some of the tools out there like ASET) to determine which are the good ones.

Anyway, when you go to GOG, take a long look at that I diamond. Talk to Jon about how the cut maximizes brilliance to make it appear whiter. I think you''ll be pleasantly surprised by how white it looks. I always am by mine!
 
Thanks again to both of you.

I''m meeting with Jonathan at GOG tomorrow morning and Mark at Engagment Rings direct in the afternoon. The original ring I posted was from a company named Diamond Source in the DD and I will also be meeting with them to view the stone with an ASET. If anyone has dealt with Diamond Source in the DD before I''d appreciate any input. They do not appear to have a website (a google search of "diamond source" reveals several companies but none appear to be the one I was dealing with in the diamond district).

One more quick question. My gf works in the medical field and is frequent using her hands both in the operating room and with patients so I would imagine the ring with hit things fairly often. She definately wants a cathedral setting. I''ve read that a thin girdle may place a stone at a greater risk of fracture. I''ve also seen some stones with a girdle with significant ranges (such as thin to very thick). I would imagine this is not a good thing. Any opinions of how much, if any, this should play into my decision.

Oooh, you''ll have a grrreat time tomorrow.

Buy insurance for the thing. My uncle is a doctor (just office visits, no surgery) and his Pt ring is very very scratched up (I imagine he also has a fairly active lifestyle and doesn''t take it off.) My aunt, his wife, has the same ring (Tiffany Lucida band) and she''s also a doctor. I work for her, and I''ve never seen her hit her ring on anything, and it looks about as scratched up as one would expect in normal wear. Wear on a ring is as much about the wearer as it is about the job.
 
The girdle issue depends on where the thin parts are. Generally, "thin" is not an issue, but "very thin" or "extremely thin" may present a problem. I looked for a "thin to medium" girdle because it would be durable enough without hiding too much weight in the girdle.

As for the medical field, if your GF works in the OR and has to wear sterile gloves and gown up, she should take any rings off and put them on a necklace chain or in another safe place. I believe rings are actually not allowed in the OR because they can break the sterile gloves. Otherwise, I do wear my rings at work when I''m dealing with patients, just not in the OR (I''m a resident, but not a surgical one) .
 
Thanks for the advice.

I''ll let everyone know how it goes tomorrow.

I found a website for Diamond Source. It''s diamondsourceinc.com. Not real impressive but they have been good in my limited contact with them. Does anyone has any good/bad stories with this company?

How lucky was that you had Doc J and Julie for advice on how they have seen rings wear for physicians!! I haven't heard of the company above, I would stick with GOG or ERD.
