When I did a search for 1-1.2 carat F IF diamonds, I got a low price of $8,979.00 and a high price of $15,605.00 so your stone falls somewhere in the middle. We cannot tell anything from the picture you posted. We would need ASET or ideal-scope images to help us determine the stones performance. If you provide the table size we could at least see how it scores on the HCA.

Is there a reason (ie: cultural) why you must have such high colour & clarity? You could safely drop down to G/H and VS2-SI1 in order to go up in size. I'm not saying you should, just that you could and still end up with an amazing, white diamond.

Missed one the table size is 57%.

Pa thanks for a quick response.
It is nice to have, and for her to say, the diamond is a flawless, colourless diamond. Also unless it is side-by-side. I am not sure the small size gain would be worth it.

Any thoughts on the dimensions?

 

[CanuckAB]

It scores 1.2. Anything under 2 is a pass so it looks very promising. The next step would be to ask for the scopes. I get the feeling this is not possible from your vendor?

I suggest you try to see this stone in as many lighting situations as possible. See if they will go outside with you so you can see it in the sun. Then see it in the shade of a tree. Try to shield it with your hand from the bright special jewellery store lights. This may help you see how it performs in multiple lighting situations. If there is any fluorescence, make sure that there is no milkiness or haziness due to it. This over-blue effect is very rare but you should check for it.

Let us know what you decide. We love to hear the back stories!

 

[Troy4c]

Sadly it is a bluenile stone. So what you suggest isn't possible until it ordered and arrives.

 

[CanuckAB]

According to the site I use, a 1.02 diamond should be 6.54 x 6.54 x 3.94 so it looks like you're right on the button!

Just saw it's a Blue Nile stone. Did you place it on hold before it gets bought out from under you? You can take it to an appraiser once you get it to check out it's performance. I believe they have a decent return policy. (Sorry, I do not have first hand experience ordering from them.)

 

[CanuckAB]

Based on what you've provided I think it has a lot of potential. Are you set on Blue Nile? If you want us to suggest other stones so you have other options to choose from, just say the word. The people here love to help.

On that note, I'm off to bed. I'll check back tomorrow to see where you stand. Make sure you let us know what you decide, ok?

 

[Troy4c]

Pretty Happy. Unless someone can suggest something that is truly better.

 

[CanuckAB]

LOL, I'd be happy to receive a 1carat F IF diamond. Is this a surprise or does your future fiancee know about it?

They are very good about returns, but in my experience it took a while to get the funds back.

Also, to OP - IF is not truly flawless. The main thing is to get a killer stone that has outstanding light performance. From the photo this diamond may or may not be the "best". I'm sure it will be lovely but if I were you I would relax a bit and check out your options before making a choice.

I'm not sure local appraisers judge light performance to the degree that PSers do. My GIA appraiser laughed when I explained that my diamond was a super-ideal. I had two ideal diamonds in hand. One was great in a number of lighting situations, but lost it in some & the other was "on" in all light.

 

[Troy4c]

I am aware IF is not flawless, minor polish mark that can be fixed to bring it to flawless but I am happy with IF.
I am aware you can't have everything. Diamond selection is subjective, even appraisers might have different thoughts.

Super happy with the diamond, unless I am advised otherwise.

Thanks for the info with bluenile.

Further, I have explored, other options, but not closed minded, if you have any suggestions?

Appreciate all comments, and suggestions.

Just based on the numbers, that stone is about perfect. It's definitely worth a closer look.

 

[SirGuy]

The numbers are within a range where it is fairly likely to be a decent performer. However, GIA cut grades are based on a 2D rounding system, and not on the actual 3D light performance (like AGS). What that means is that the numbers for say, the critical pavilion angle could be all right on the money, or they could vary widely (some high, some low) and just average within the accepted range.

The reason why you pay a little less with BN is that you're buying blind. It could be pretty good or it could be great. You won't know without images or without seeing it with your own eyes. GIA "triple excellent" (not "triple certified as you called it) is unfortunately a fairly broad range.

The numbers and price are enough to warrant a closer look. I wouldn't necessarily commit to it unless you have to at this point.

It's easy to overthink this stuff and get what we call "analysis paralysis," but unless you're in a time crunch, exercise the return policy if you need to and evaluate its light performance for yourself.

 

[Troy4c]

Sorry typing too fast and thinking not at the same speeds. Meant to type
"Triple excl. certificate"

You are correct, there is no real way of knowing a diamond from a cert. the light return has to be determined.

It is too hard to tell from the picture, I will just have to see it in all lights. Luckily there is a return policy.
I hope it all the facets work together nicely.

 

[Troy4c]

I am greatly concerned with the lower facet length 75%. I am losing sparkle, and greatly concerned with GIA rounding. Diamond enthusiasts and experts please help. 80% seems to be the better option?

 

[krisjon]

Again, don't get caught up in analysis paralysis. There are numbers and then there is actual experience. Get the diamond in your hands. See what it looks like in person. Send it to an appraiser who can do an ASET and/or Idealscope, so you can assess light return and ease your mind. If it doesn't live up to your expectations, send it back.

For reference, my fiance's e-ring AGS 0 stone has 76 lower facets and it's a spectacular, fireball of a stone.

 

[Troy4c]

Thanks for the prompt response. Very encouraging.

 

[krisjon]

The numbers on that stone should lead to good results. Don't overthink it too much.

GIA Ex grades can be really out of whack, but even with averages, this one is in the ideal range you look for.
