Recommendation on Solitaire ring diamond

[gps470]

Looking for advice from the experienced members here.

This would be gift for wife on 10th anniversary. $10k-13k USD range is what I am looking in (can go up by 10% if really good deal). Don't have much of preference, but based on the recent readings I did on the forum, I have come up with list of these 8 diamonds.
Color : G+, Clarity : VS2+, Light Floro, VG+ polish and Excellent cut.
I am looking for the best value for the price among these and would be really appreciative of any comments or suggestions members can provide : (Sorted high to low in price)

http://diamonddealfinder.com/enquiry.php?id_field=5595149 (I liked this one quite a bit, even though its slight over-budget)

I only ran the HCA on the first 2, but saw that the CA on the first choice is 35.5, and that works better with a 40.6 pavilion, as opposed to 40.8, so not surprisingly, the HCA came back as 2.6

The basic specs on the second one looked better and when I ran that one got .9 HCA. Does the supplier have the stone and can they do an idealscope or ASET of it?

I didn't run the JA stone, because I already saw the CA and PA were a bit out of specs for what people generally recommend here.

here's the hca tool- it can help you weed out some stuff:

Can you get an idealscope for this? 35.5 is a little high in the crown for a 40.8 pavilion

Should be nice.
Please let me know if there is anything I missed from the post.

Thank you!

I went through them really quick...see comments above.

 

[gps470]

Thanks bunnycat and tyty333.

I have emailed the supplier and talked over phone as well. Waiting for the details.
Once I have it, I would respond back here. I didn't realize the importance of HCA till now. I have eliminated the ones over 2 leaving only 4 in equation.

Having said that, do you have any recommendations in this price range (10k-13k) other than what I posted ? Its just that being a novice, I don't have much confidence in my choices.

Thanks again.

You are welcome. It can't hurt to look while you are waiting for more info on your shortlist. I haven't had time to check JA because it takes so long to sift through things, and so I checked some vendors that already have light performance info.

Saw this on Whiteflash:
http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3772287.htm
http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3774789.htm

Then I checked BGD real quick (sorry, I do love my BG stones so I always check there).

This one is an H, but it has fluor, which I think helps face them up a little whiter, though H is definitely white enough for me anyday with or without fluoro.

http://www.briangavindiamonds.com/diamonds/diamond-details/1.510-h-vs1-round-diamond-ags-bl-104091071001

and they also had a BG Black up, which is their new line:

Bunnycat, what a coincidence that as soon as I posted my reply, I got call and email with details.
I was recommended http://diamonddealfinder.com/enquiry.php?id_field=5587130 over the others and have been told that its clear to eye. HCA came to .9
GIA Report : https://www.eternitybyyoni.com/cert_view_gia.php?product_id=2458230
Total price a little shy of $14k.

What are your thoughts on this piece and the offered price, and the advice for the next steps ?

That one was the suggestion I made to get more info on in your first post. I still say you need more info.

I can't tell you anything about pricing, and you have as much or more info on the stone as we have here right now regarding performance. What people really need to see here to help you better is an idealscope image to review the light performance. (The red and black picture if you click on any of of the stone links I posted).

Unfortunately, no ASET or Idealscope is available for this stone. I am not sure if I can do anything more here other than checking online if this stone is available at any other place(s) and they can provide some extra details.

Do you need to buy from them? Or are you open to looking at stones from vendors that already have, or can easily get Idealscope or ASET images?

Alternatively, you could buy a little idealscope (about $25) and if the stone has a return policy (I wouldn't buy any stone without one), you could get it in and check the performance yourself very easily....The numbers sound promising on it, and the vendor thinks it is the best of your choices so you could get it in to have a look as long as there's a return policy in place. That might be a good option for you. Idealscopes are very easy to use. I have a basic kit myself which has a little light dock to set a stone in but the basic thing you need is the scope part...

First of all, thanks for all the help you are offering, bunnycat. I know its simple to ignore and move on to next post, but I think people like you are making this forum valuable and helpful for all.
Coming to your question : Not necessarily. Its just that I have got the best price on that stone from them. Return policy is 10 days.
I was able to get an image and 2 videos, which I have uploaded to my dropbox account. I don't think it would make much of a difference but something is better than nothing
[**edited by moderator, please upload pics to forum directly per our policies**]
One thing I noticed on the GIA cert was Apr 20, 2015 certification date. Should I be concerned about that ? Most of JA, WH and BG stones have Mid to Late 2016 certification dates.
I am still checking with other jewelers online if they have extra images, as this stone is sitting in NJ and I think is available to most of them.

you might try looking up the cert number on James Allen, if that is still possible. They can do an IS if they have it, but then, so could you if you get the stone in. And you'd only need 5 mintues with the stone to know (and it really is a good candidate)....and there are plenty of other stones out there, probably with similar specs but you'll have to trawl the deeps, as it were....

Otherwise, if you prefer having all the performance metrics done already, yes, it will cost you more, but it will save you many hours and possibly days or weeks of frustration (and that is worth it to me....) Plus, the branded cuts will be guaranteed performers, that's why they are branded....(Whiteflash, Good Old Gold, High Performance Diamonds, Brian Gavin...you can find them easily there...I provided some stone links earlier on...)

 

[EvaEvans]

I would definitely get the D or E, VS1, instead of G, VS2. Diamonds GIA 6222436126 and GIA 2237749031 are excellent choice with exceptional color and clarity. I would buy one of these!

After weeks of going round and round, I bumped up my budget a bit to ~17k. Being a beginner, I am still confused between which one has an edge over the other. What do you guys think of these 4 ?

Hi, gps, sorry if I missed this further up but is there a reason you want a high colour/clarity combo? A VS2 should be eyeclean and unless your wife is especially colour sensitive you could go down to a G or even H. With your budget you could get a lovely superideal cut-

Any one of these would be gorgeous...a G/H in a Branded Super Ideal cut is going to be very white unless you are super color
sensitive.


Actually I might recommend this one for you...it's a G/VS2 1.67 $15,763 wired so well within your budget. It is an Expert Selection.

[gps470]

What threw me off was the comment : "I would definitely get the D or E, VS1, instead of G, VS2", which made me change whole equation. This is going to be my first diamond, and I am probably being extra cautious to make sure I don't have to do return/rebuy, hence the reason for going E/F color. If G/VS2 is going to be good enough, I think my initial choice is still available :
http://certs.rapnet.com/userfolders/49864/Certs/1199879918.pdf
1.61, G/VS2, .9 HCA and Eye clean and under $14K.

Should I go for that or the recommendation is to stick with WH and named brands, in which case,
http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3726902.htm might be more suitable. The difference in price would be ~2K which I can put towards a beautiful setting.

I always take color commentary with a grain of salt. Everyone has different tolerances and preferences, and so I try not to let my preferences enter in to my advice here, if I can avoid it. My personal advice is to go look at Gia graded diamonds to decide where your color tolerance lies. There is no right or wrong color. Some people prioritize color over cut. Don't forget, some posters may live in countries that prioritize one or the other thing. I think in Europe, high color tends to be a priority, whereas in America, well, we probably tend towards size.

I would bet, however, that your tolerance is a lot lower than d or e in real life. People let themselves get scared by hype or pressure.

For instance, I am color tolerant down through I, and then it is case by case after that. But when I posted stones for you earlier, I tried to stick with g, since most people are ok down to that.

The good thing about WF, is they can do you a video of a couple of the in house diamonds, which would not be possible with some of the other places you have searched.

The crown and pav angles are right on the edge with that one, but it could still be alraight. They have performance metrics up. If you could pick one or two others, they could do a comparison video for you, and y'all could talk about it. On the stone in your link (the 1.67) the red and blue blurring at the center in the actual ASET image (red/green/blue) is what you want to focus on asking about, IMO. Maybe John, Karl or Garry will see this and can comment on it. It's something I'd want more info on, or compare to another stone. or you could start a separate thread on the 1.67, and that would probably generate the attention.

Compared with:

[Bedot]

Unless your significant other knows about diamonds extensively, whether or not she is color sensitive wouldn't likely matter if you are picking an F diamond over a D diamond. There's just no way an average person would know the difference without trying to really see and investigate.

People on here say they are color sensitive, but they are also diamond experts basically. Most diamond wearers don't belong to this site nor could they tell minor color differences in the colorless range.

Keep a good balance with all your criteria and you will find an excellent diamond within your budget.

If G/VS2 is no good, F VS1 should solve any issue color or clarity wise. Going higher than that addresses personal concerns more than actually improving the visual aesthetics. It is all preference at that point.

This. The curse of the ever growing wallet (or credit card debt). This happened to me too when I bought a diamond last month. The more I learned about diamonds the more I wanted one with "better" specs. A game that never ends well for the wallet.

http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3172036.htm

If you decide to get a video on the WF diamonds, I'd also ask about potential painting on http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3737017.htm and http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3644861.htm... Their ASET images remind me of how the "crown-only painting" ASET reference images look at ~1-2 degrees. Not that painting is always a bad thing, but make sure you consciously go into the purchase knowing for a fact whether the diamonds are painted.

I will have ASET/Idealscope images shortly for this. Its HCA 1.1, Eye clean stone.

All the angles look good. It'll be good to see the IS and teh gemologists opinion. I think the pav angle said 40.7, though it wasn't listed for some reason in the link. I wonder why they didn't spring for the other AGS report, the Platinum one with the computerized light performance report?

HCA is not necessary when you have an idealscope/ASET as here they show excellent performance.

HCA in this instance is limited by the fact GIA round their angles. This stone is

55 table- 35/ crown height 15.5%
0 culet,-41 pavilion / pavilion height 43%

This could be. 34.75/40.9 combo (HCA less than 2) or a 35.249 / 41.099 which would be > 2.

Here HCA is limited by rounded GIA values. Saying that, 43 % pavilion depth with a 41 pavilion is better than if it was 43.5% as it's likely the pavilion is not rounded down, but rounded up

Mathematically for a diamond to have those values, that carat weight, that depth percentage, with a table of 54.5 to 55.49, I can find that the average pavilion angle is almost certainly below 41, and the crown to be highly likely to be less than 35. This would the make the diamond HCA <2. This is all academic because you have the reflector image. HCA is used to calculate theoretical light leakage on rounded values, it is entirely useless when you can see there is no actual leakage. Hope this helps.

I've uploaded your idealscope image as the mods will delete your links, like the last ones

FYI it's great, just make sure it's not a cloudy diamond.

Aah damn, didn't realize till just now that links are not allowed. From Workplace, uploads are not allowed, so I have been uploading to dropbox from cell, and sharing link directly. I will remove the previous links. Sorry about that.

Cant edit the post somehow. Have reported them as Violation, hoping that will get them removed.

I believe this is the IS image for the JA stone and not the WF expert selection stone. It looks good. What did the gemologist have to say about it? Anything?

 

[gm89uk]

Yes it is, that was a separate point from the rest of my post.

 

[gps470]

JA said that its light performance and sparkle, both are pretty good. I am not sure what else to ask, as they have provided IS, AGS report and video, all three.
Having said that, what do you suggest on this piece at this price range ?

Is this the G vs1 1.76 stone? How much was it? Can't see price as you've reserved it.

Edit: is this the 18k plus stone? It looks like a great stone but I wouldn't pay that much for that carat weight. Unless you're in dire need for a G I would spend my money on a well cut eyeclean H Vs2/si1 and save >3k. Don't pick based on online videos, go into the store and look at lots of GIA / AGS certified G/H stone (in a back lit room). You may find (as with most people) that the difference is far too insignificant and save yourself lots of money. Especially in a well cut MRB solitaire.
