I need to find a diamond ASAP because I plan on popping the question no later than mid July. Been searching and learning for weeks now but I feel as though sometimes it gets too complicated with my OCD.

I found a site where I can purchased this stone unseen. I've included all specs and HCA score

HCA results
Light return: very good
Fire: very good
Scintillation: good
Spread: excellent
Total Visual Performance: 2.8 (worth buying if the price is right)

Diamond specs GIA
Round brilliant
6.33-6.34 x 3.74mm
.9 ct
G color
VS2 clarity
Excellent cut
Excellent polish
Excellent symmetry
No fluorescence

Table: 61%
Depth 59%
Crown 33 degrees
crown height 12.5%
Pavilion 41.2 degrees
Pavilion height 43.5%
Cutlet none
Girdle thin-medium (3%)


Price $3800

I am buying a second hand ring and will take the diamond and change the setting. Is this a good buy? My budget is actually $4800 for just the stone and I figured this was a way to get a stone I was looking for at a much better price. I could use the leftover for a trip for us or something.

Spec wise the stone seems great but I am not familiar with the HCA and thought I would like to save the 1k I'd rather spend it if it means I can get a much more shiny diamond. What do you all think?

Given that I can't see the stone and pics never do it justice. Would you buy this just based on the numbers?

Thank you all

the idea is to put the diamond in a setting such as this one.

No, that's a straight pass. I wouldn't buy that stone with those angles. They are not complimentary.

Here is some reading to help you:
:read:
The entire purpose of faceting a diamond is to reflect light.
How well or how poorly a diamond does this determines how beautiful it is.
How well a diamond performs is determined by the angles and cutting. This is why we say cut is king.
No other factor: not color, not clarity has as much of an impact on the appearance of a diamond as its cut. An ideal H will out white a poorly cut F. And GIA Ex is not enough. And you must stick to GIA and AGS only. EGL is a bad option: [URL='https://www.pricescope.com/community/threads/egl-certification-are-any-of-them-ok.142863/']https://www.pricescope.com/community/threads/egl-certification-are-any-of-them-ok.142863/[/URL]
So how to we ensure that we have the right angles and cutting to get the light performance we want?
https://www.pricescope.com/wiki/diamonds/diamond-cut
Well one method is to start with a GIA Ex, and then apply the HCA to it. YOU DO NOT USE HCA for AGS0 stones.
https://www.pricescope.com/wiki/diamonds/holloway-cut-advisor
The HCA is a rejection tool. Not a selection tool. It uses 4 data points to make a rudimentary call on how the diamond may perform.
If the diamond passes then you know that you are in the right zone in terms of angles for light performance. Under 2 is a pass. Under 2.5-2.1 is a maybe. 2.6 and over is a no. No score 2 and under is better than any other.
Is that enough? Not really.
So what you need is a way to check actual light performance of your actual stone.
That's what an idealscope image does. https://www.pricescope.com/wiki/diamonds/firescope-idealscope
It shows you how and wear your diamond is reflecting light, how well it is going at it, and where you are losing light return. That is why you won't see us recommending Blue Nile, as they do not provide idealscope images for their diamonds. BGD, James Allen, GOG, HPD, ERD and WF do.

The Idealscope is the 'selection tool'. Not the HCA.
So yes, with a GIA stone you need the idealscope images. Or you can buy an idealscope yourself and take it in to the jeweler you are working with to check the stones yourself. Or if you have a good return policy (full refund minimum 7 days) then you can buy the idealscope, buy the stone, and do it at home.


Now if you want to skip all that... stick to AGS0 stones and then all you have to do is pick color and clarity and you know you have a great performing diamond. Because AGS has already done the checking for you. That's why they trade at a premium.

Hi there. First, congrats on your upcoming proposal! That's exciting.

Now, you're in the right place for quickly improving your knowledge.

Would I buy that just by the numbers? No. I'd like to see an Ideal-Scope at least. Maybe an ASET too for kicks. Happen to have the crown and pavilion heights? The numbers I see I don't care too much for.

This seems to be a 60/60 stone. Is that something in particular you're looking for? 60/60 stones have big tables, shallow crown angles, and short crown heights. If cut well they tend to have more brightness (white) compared to dispersion (color flashes, or "fire").

Just something to consider. :)
 
Don't know you budget but I can guess it's around 5500-6,500

Pick one of these instead:

http://www.jamesallen.com/loose-diamonds/round-cut/0.91-carat-g-color-vs2-clarity-excellent-cut-sku-319512 (put on hold and ask for idealscope image, and they will get you one. If it is on hold already, then ask them to email you if it become available, the price is great on it).
http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3150819.htm?source=pricescope
http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3114504.htm?source=pricescope

This one has great numbers and will be eyeclean, just ask for B2C to get you an image and an idealscope, and they will do that for you:

Then there are these, you will FIRST have to ask them to tell you if they are eyeclean, then if they are, tell them to get you an idealscope and an image:

thanks for the help. i cannot get any ideal scope or aset as it is a private stone selling on a second hand site. didnt even know what a 60/60 stone was.

i update with crown and pav height.
 
$4800 budget per the original post. That 0.9 carat requirement (well, interest) might be hurting the selection a bit.

I'm with Gypsy; cut is king.
 
Your budget is low. You should drop to 80 points.



Also, you DID post crown and pavillion:
Crown 33 degrees
crown height 12.5%
Pavilion 41.2 degrees
Pavilion height 43.5%

i am a little overwhelmed by all your choices. def appreciate the help. i can up the budget for the stone to about 5200 if need be (in order to go up in clarity/color) since i recently sold a lot of my photography stuff and though i wasnt planning on using that money for this i want my lovely 'wife' to love her ring.

seems whiteflash expert selection is the way to go so i dont get stressed out.

also...i am scare with stones under G (like h i j)

i guess my problem is that i have seen very few diamonds in person and so maybe i have an incorrect assumption that anything under g will look yellow. i dont want my gf putting her ring next to a friends and having hers be yellow and suddenly hating it (you know the hers is better than mine mentality) she is not that kind of girl anyways but id rather avoid.
 
Okay so...

More to read:
ON COLOR:

It is important to remember is that color is graded FACE DOWN. Where there is NO light return. Not face up where there is light return and refraction. You wear diamonds set. FACE UP.

Within one color grade, even the labs can't agree on the color grades of stones and something could be a "high" H or a "low" E. So... no. Not really. Within 2 color grades it is hard. Not impossible. But very hard. And it gets harder once set. If you are talking ideal rounds, or any stone with ideal light return and no sharp corners it gets harder still because the ideal light return masks body color.

Generally we say to be conservative stay above H in a round. But MANY people have happily bought white I or even J diamonds when trying to eek out a little more size. And those are still WHITE, they are just a slightly different shade of WHITE. You don't get YELLOW until you hit N-O-P. So you are safe.

_327.png

This is how I think of it.

Ever gotten one of those HUGE paint fan decks? Where there are literally 100s of colors of whites? And when they are RIGHT next to each other you can TOTALLY tell that one is bluer/colder and one is a bit warmer and which one is one is TOTALLY warmer. One there's one that's slightly greener. One that's slightly pinker? But really. They are all white?

Then you pick one after agonizing over this white or that white and when it's on the walls and people are like: Oh. You painted again. And it's STILL white. Great.

And you're all... BUT it's BLUE white. Or it's a WARM white now. It used to be ____ white. It's TOTALLY different.

It's like that. You are talking about shades of white. D is colder... J is warmer. But it's all white.

YES. If you have an accurately graded F and an H THAT HAVE THE SAME PERFORMANCE you are going to be able to tell them apart when you compare them (from the side, not from the top). Just like you would be able to tell if you painted your walls a warm white, but painted the crown molding a cold/straight white. But both are STILL white. And it is very unlikely that your lady is going to meet someone with a stone as well cut as hers that has much higher color. Because to be mostly, most diamonds out there are crap and they are loosely graded from bad labs or poorly cut.

So, I want you notice all the qualifiers thought. I'm talking about stones with the SAME performance and from the side. An ideal H will out white an F that has compromised light performance from a poor cut.

NOTHING impacts the appearance of a diamond as much as cut. CUT is king.

You want the shinest whitest and brightest diamond out there: Cut is King. No other factor, not color or clarity or anything else impacts how white bright an shiny a stone is.

I think you can VERY safely go to H color. And if you can expand your budget to 5200, you can do that.
 
that def helped a lot. didnt know color was rated face down. i dont think anyone will be looking at the stone from the side or underneath as it will either be set in a solitaire or a simple halo.

so given the new budget of 5200 for the stone and sticking to an H or higher. what are your recs if we also stick to .9ct or above. last request i promise. THANK YOU! its 2:37am here. i hope youre somewhere where its normal time. :wavey:

i just emailed my consultant at b2c about these as well as the 1ct j color. i had asked to see some stones in person as they are located very close to me but he was unable to get the stone from their supplier. so hopefully he can be of assistance with these. thanks for your help once agian.
 
Even if they don't have them in you can get one, and return it if you aren't happy.

Make sure any diamonds you are looking at have great light performance (HCA under 2.0 plus idealscope).

Hi Atheros,

I just wanted to add, if you are unsure with colour grades, try to view some in person so you can see for yourself. If you have a Hearts on Fire dealer near you, they go up to J colour I believe, that way you can see how some of the lower colour grades look in person, a great cut will help even an I or J colour stone face up whiter, but if you prefer to stick to H colour, that's no problem whatsoever. Although you might see a hint of warmth from the side view, that might not be an issue at all. Or look at some GIA Excellent cut grade for comparison purposes ( run the GIA Ex through the Holloway Cut Advisor to find the below 2 scorers out of these), or AGS0 cut grade, make sure you also compare diamonds of a similar size to the one you are considering to get the best idea. Also a tip here concerning us ladies comparing diamonds, time and time again I have found that the main attraction is most definitely the sparkle, get a superbly cut stone and it will not only blow your GF's socks off but those of her friends too!
 
Here are some selections for you. The diamond below is $10 over budget :tongue: , it's a D colour so no worries there about any warmth! It is beautifully cut, a slightly different ' flavour' if you will, to the Superideal branded diamonds we frequently see here, but it's still a very fine make and could be a fantastic choice. The crown angle is slightly shallower than those of the Superideals but that's not an issue, it could mean this stone favours brilliance slightly more than fire or coloured light at an estimate, but one of the vendor's gemologists could describe its performance to you if interested, it could be a very bright, brilliant, icy diamond! If interested, reserve it and request an Idealscope image, then post it here once you have it.

If you would consider I colour, this might be an option.

http://www.whiteflash.com/loose-diamonds/round-cut-loose-diamond-3075981.htm?source=pricescope

H colour well within budget, you would need to check it is eye clean to your specifications, around $4500 with bank wire.

http://www.goodoldgold.com/diamond/11531/
 
H should still look very white when set, even from the side. I is where most people can start to see tint, esp. from the side. I have an H and an I, and I have definotely taught myself to see tint in that I from the side. J is too yellow to be called white, imo. It looks yellow from the side to my eyes. There are lots of people here who like J, but J against F/G/H sidestones in a setting will show a color difference. Also, some of the J are chameleon or have a body tint that makes them look better in yellow gold than white gold of platinum. (Just saying.) I'd set H and the cutoff. G or H would be nicely white when set.

The problem with tint is that you can train yourself to see it over time. So what looked white enough at first can start to bother some people after they've studied the ring a while. Of course seeing tint and disliking it are two different things. Depending on skin tone, some people prefer a "warmer" color diamond and some prefer the icy ones. Just another point to ponder. There's nothing wrong with any color of diamond, even J/K or lower, if you/she like it.

i am confused with this ring because the idealscope image shows the arrows all in white. i thought white meant light leakage. the whiteflash website shows all their idealscopes with dark arrows and white hearts.

i am missing something.

It's fine, the B2C image is computer generated and that's how they look, the white arrows are normal, the WF IS images are taken of the actual stone, not a computer simulation so as you notice, the arrows show dark and hearts as white. White or paler areas can show in either type of image as leakage depending on backlighting and set up, in this case it's an excellent image with no concerns.

i am not a fan of the whiteflash settings. they seem a bit too classic for me. ornate so to speak.

i am assuming if i buy the 1ct diamond, i should set it on a halo to hide the j color a bit.

these are the 2 settings i really really like right now from b2c.

That is not an idealscope image. That is an arrows image. Totally different. Arrows images have red and white. Idealscope images have black and red (and white and pink are not good).

There is no idealscope image for that one, just an ASET image. And that is strong.

We can't help you there. We know nothing about her or what she likes. Has she shared what she wants with you?
 
I was referencing the center stone. Shed would be happy with either setting.


I assume though that if i choose the 1 ct a halo setting would hide the j color right?

I suppose that could also depend on the color of the stones in the halo! Great cut goes a long way towards helping color.

Thirty years ago, the trend was color and clarity. Solitaires in white gold or (more frequently then) yellow gold, with good color and few inclusions. But part of that was because the cuts weren't as consistently good as they can be today. You almost needed the color to help with the mediocre cut's part in the light performance.

Cutters today are capable of doing superb jobs. Many knowledgable buyers feel more comfortable with a lower color with ideal cut. Heck, some of those stones will have more brilliance and fire than colorless stones with mediocre cut.
 
It's not just the color of the stones in the halo, it's also the performance of those. I have an F center. And my halo is all F/G. It still out-whites my center stone in certain lighting because of the performance difference between the tiny facets of the melee and the large broad facets of my center.

It also matters how high up the stone is set in the halo. Some halos have the stones set very high so the sides are very visible, and show contrast next to the melee stones.

If you want the sides hidden, go for a bezel set halo.
