Hello! First off, I would like to thank you all for helping me find some really great diamonds. I really appreciate everyone that has given me advice as well as their opinions!

With your help, I have finished my engagement ring upgrade! I purchased the 1.75 RB VS2/I stone and set it into a custom Halo setting. I took the original 1.28 RB SI1/H with med blue fluorescence and sent that off to be set in the 3 stone Vatche Swan with .40 side stones that I bought from WF. I hope to have that ring back in a couple of weeks so I will be sure to post pics.

In the meantime, I am starting new projects that I need some advice on. Although I already have 1.5 ctw studs that I'm keeping, I was looking to get some 1.0 ctw studs to be able to wear with some diamond jackets that I received as a present years ago. At any rate, I happened to find what I thought was a wonderful deal on a .48 VS2/D AGS000 stone that once set would fit perfectly in the jacket. I think it technically may be classified as a FIC?

My concern is that when I called an online vendor to try and match the stone, I was told that the crown angle is steep with this diamond and that there would be a "misalignment of the angles that would affect the brilliance in some lighting". I've looked at the diamond using my handy idealscope and there is minimal light leakage. The diamond has a ton of fire and I think it looks great in all modes of lighting but now I'm wondering if maybe I don't know what a good looking stone should look like! I have seen a stone that had a 35 degree crown angle with a 41.2 pavilion angle and I could definitely see that it lacked brilliance and scintillation and the IS image showed that too. This stone certainly doesn't look like that one...

Here are the stats:

Depth: 62.1
Table: 55.6
Crown Angle 35.6
Pavilion Angle 40.6
Upper 56
Lower 76

score excellent in light return, fire, and scintillation scores 1.4 FIC on HCA

Do you think the misalignment of angles was meant in terms of trying to match it to a less steep stone?
 
That is not steep enough to be a fic, or very difficult to match, imo
 
Oh, so in your opinion is it worth keeping the stone and continue looking for a match? The representative mentioned that 35 degrees was the cutoff for what they deemed ideal and their diamonds did not have crown angles beyond that. Having read posts on the forum, I was under the impression that there were certain crown/pav angles that were OK and could result in nice looking stones (shallow pav to compliment steeper crowns). Would you say that this particular diamond's combo is good and to keep searching? Of course, the rep offered two of their diamonds that would make a great match for each other at which point I would've just used this in a pendant or something.
 
If it is the size you are looking for and you are happy with it, a match can be found for you.
 
Ohhhhh something I've not heard of before. What is a FIC?
 
Well, I suppose I'm not sure anymore. I thought diamonds that had crown angles greater than 35.5 with a shallower pavilion were considered Fiery Ideal Cut stones. Could someone else explain?
 
Usually 36 CA. 32 and below, with complimentary proportions, is a BIC.

What's the budget for the match, and what is the diameter?
 
I'm looking for a 5mm, similar color as I would like to one day be able to use them in another 3 stone ring. I would like to keep the budget low..maybe around $1300?

Here's a link to the report.

Would this crown angle diminish some of the light return in indoor lighting? Meaning, if it were 35 or less, it could perform better?
No, it would have a different look however.
This one is close enough to a Tolk that the visual difference would be slight.

Fics start around 35.5 degrees per the hca score.
If the HCA says its a FIC its a FIC.

That a vendor has a preference for stones with a crown under 35 degrees does not mean that ones with crowns over that are bad. On a fic the pavilion and lower facets match the crown and optical symmetry is decent they can rock ones world just as much as a optically symmetrical near tolk 34.8/40.8. They just look a bit different hence they are called FICs by Garry the inventor of the HCA.

This is a look that is an example of FIC: http://www.jamesallen.com/loose-diamonds/round-cut/0.50-carat-f-color-si2-clarity-good-cut-sku-52910

Do you have a picture of yours, or an AGS report number?
??? There is no evidence that that is a FIC and the start of the FIC range is not that deep.
Going by depth does not make a FIC.
Of course I didn't go by depth. OP's stone is not that far into FIC territory, certainly not as far in as the one I posted.
 
JulieN - Thanks for the recommendation on matching stones. I'll check those out..

Karl - Thanks for your input! This stone seems to give off a lot of spectral color (if that is the right term) and seems to sparkle nicely. Can I assume that in this diamond's case, the pavilion and lower facets match the crown?

Yep hca says so, the AGS0 cut grade says so and I say so :}
 
Haha! Thanks!
 
I've searched the threads but couldn't find any info on what to look for when pairing two diamonds. Aside from similar diameter and staying within 1 color/clarity left or right, what else should I be looking for? For example, should I stay within a certain range as far as crown angles, pavilions and depth percentages?
 
Hello - I have been following this topic with interest because I have a FIC (ER), so I was curious on everyone's thoughts. From my research on picking out loose diamonds for studs, I think it is important to get the table size to closely match (in addition color and diameter). I suppose it would make sense to also try to find an FIC so they have matching fire/sparkle but other experts can weigh in on that...Since they are far apart when you wear them, it might not be a big deal. I didn't even know about FIC when I bought mine so now I am curious to look at the certs again!!

Good luck!!
 
Thank you, I'll be sure to keep those things in mind during my search! I imagine your ering must look like a fireball! I showed my husband this diamond next to a similar size ideal cut loose stone that I have and he asked me if the newer one had more facets because he could see "more rainbow effect". I like it so hopefully I'll find a match soon and my next post will be pictures of cute little studs in SMTB!

JulieN and Karl_K, thanks so much for your input and advice as well!
