Our fellow pfer ame who knows diamonds very well. i am in the same boat for diamond searching and she helps me so much. :)

i learn that table size and the depth, also the size angles are matters.

This is the information she advices.

"Total depth between 59 – 61.8%Table diameter between 53 – 57%
Crown angle between 34.3 – 34.9 degrees
Pavilion angle between 40.6 – 40.9 degrees
Girdle thickness between thin to medium, faceted (bruted isn't bad, but faceted would be better)
Culet size: none"

Hope that helps. GL to ur finding.

Thanks Phoebe. Has it been difficult to find a stone within those ranges?

ame said:
I am hoping those are just poorly taken photos but the culet doesn't look to line up properly with the table at all which makes me question those angles being consistent around the stone/symmetry. I also don't like the numbers together. I think it's a LITTLE deep for that table percentage, and that the pavilion angle is just a hair off for working well with the crown angle.

I think you can find a better one.

What vendor are you working with? Maybe we/I can help you search their inventory?

Thanks so much for your input! :) I guess I'll continue looking. I'm located in NYC. Who do you recommend? And, just curious, do you think the images were just a poorly taken if GIA graded the symmetry as excellent?

Personally, I am not willing to pay the premium for a diamond with such a high clarity. You could save a lot by going down a notch or two. Check out Pricescope. It is a site full of diamond experts.

Personal preference entirely, rank cut first, but then go with your own personal threshold. I prefer VS1, personally, because it's still almost guaranteed eye-clean but it isn't at a premium price point for the clarity. A very well cut stone can mask many inclusions. VS2 is USUALLY ok, but those you have to see in person to confirm they're eye clean. While they *should be*, they aren't always, because a tiny and still visible black crystal can qualify as VS2 based on location. SI clarity stones are lots-of-photos-or-in-person-required-viewing stones. Those are not stones you want to buy blind because they're never just guaranteed eye clean. You can definitely find eye clean SI stones, however you can't just assume one will be and you need to see it for yourself.

I was initially looking for VS stones but this came along and the price difference was minimal. I.

Possibly. I don't always agree with GIA's cut grading. Their net for what they deem "excellent" is gigantic.

In NYC area I like Good Old Gold in Mass Park on Long Island actually, the LIRR will take you right out by them, there's a stop like right across from the plaza they're in on Sunshine Hwy. The amount of data and testing they do on their stones is unmatched by ANYONE. I prefer to work directly with Jon though--if you send a message and put "ATTN RHINO" in the subject they usually will involve him. Another worth a look is Engagement Rings Direct, not the same level of testing and whatnot, but good service as well.

If you're looking outside of NYC to online vendors, Brian Gavin Diamonds has a lot of data on their stones as well and if you are willing to consider them, they have a line of "blues" (aka fluorescent stones) that are incredible, and will net a slightly larger stone or higher color/clarity in some cases than you'd get if you weren't looking at one with fluor. Worth a look.

If you're willing to share budgeting, even if you PM it to me, I can help you pick a few worthy ones. Being realistic with your budget compared to the size/color/clarity is going to be important.

These three are probably "higher" price than a few others out there but I think their merchandise and especially in GOG's case the amount of data and testing they provide is worth the possible extra cost.

Yea that sometimes happens. The concern I have with this being a minimal price difference is the cut is not really that great, so it's less pricey than it "should be".

It is not easy, especially I work oversea now. I think there's many great site that recommanded by pfer. You might want to check it. I have find a nice one but little pass my ideal price, so I let it go. There's many knowledgeable diamond lover on TPF. I am sure u will find a good one :)

I would definitely go to an SI1 if you can see the stone in person or if you trust the person viewing it for you and you have an excellent return policy. What ame said is completely true; you cannot depend on an SI1 being eye-clean or the inclusions not affecting light-play, so it isn't something you should buy "blind" or be unable to return. But I think it provides an excellent value for the money. But clarity means different things to different people, and as they say, ymmv. Some people, for many reasons, prefer very high clarity stones and that's a completely reasonable and valid choice, too.

Thanks so much. :)

As to the original stone, I believe that the stone is just not 100% straight in the idealscope image. I think the stone is fine. All the measurements are fine. Here are the parameters I use which normally will land in ideal cut territory:

table: 54-58

depth: 60-62.3

crown angle: 34-35

Pavilion angle: 40.6-41.0

girdle: thin, medium, slightly thick

Like Ame, I prefer VS1 since it is usually very clean and you don't pay the premium for VVS. Many, many people go to VS2 which is usually eyeclean, and some go for SI1 to get larger sizes but you really have to look at those individually because some are eyeclean and some are not.

Hi DS! I'll ask to see if the dealer can send me a clearer image. Thank you for your knowledgable input!
