Hi,

Just want to say thank you for having such an informative website to help newbies like me make a more educated decision (and saving me money).

I am creating a 3 stone engagement ring using two european cut side stones (which have been in my family for years), and an american cut center stone.

Here are the specs of the center stone.........I have not received it yet, it was ordered online. Would appreciate any input as to what you think of it in terms of how "fiery" and brilliant it will look. I know alot depends on basically my preference and looking at the stone as all are unique, but would appreciate any input...

GIA cert.
.93 ct
H
VS2
Excellent cut
Polish: VG
Sym: Ex
Depth: 62.8%
Table: 58%
Girdle: med to slightly thick
Culet: None
Florencence: none

Secondly, a couple questions about the setting......
1. Is there any particular way I should "angle" the side stones to enhance the center diamond? The side stones are H - I in color and probably not cut as nicely as I am assuming the center stone will be.

2. Is there a "best" way to set the center stone so that it does not end up looking like an anniversary band. How high can I set it before it looks dumb or weird.

Any ideas/input/advice would be greatly appreciated! Thank you in advance!

Thanks,
Terry
 
Hi Terry and welcome!

Just to clarify, when you say America Cut diamond, you are referring to a modern round brilliant cut diamond? If so, the stone is rather deep, we would also need the crown and pavilion angles for the diamond in order to evaluate it and the diameter in MM. The star and lower girdle facets would also be useful too please if you can post those, all of the above info can be found on the GIA report.
 
Do you have the crown and pavilion angles of the diamond?

Settings are pretty stock. I think a jeweler can help you out. In my opinion, if the sides really are not as well cut as the center, it would be a mistake to make a three-stone out of them. Wait and see how they all look together.
 
Hi,

Thanks for the repiles. I believe it is a round brilliant cut. Here are the crown pavillion specs...(sorry, I hope they make sense, I tried to ascertain what was what off the GIA cert.)

Crown: 55%
Crown: 34.5 degrees
Pav: 41.6 degrees
Then there is something by the girdle that reads: 4.0%

Hope this helps!

Thanks again,
Terry
 
Not a good stone. Pavilion angle is too big for that crown angle.
 
Hi again,

Sorry.........I guess that was another question pertaining to the comment from the second reply. The side diamonds I really want to include mainly for sentimental reasons.........even though it may be not ideal to make a 3 stone ring out of two side diamonds not cut as well as the center, according to the "excellent" cut grade per the GIA cert. I''m not saying they are necessarily cut "poorly", I just don''t know their make due to how old they are. So for the sake of arguement, lets assume they are cut somewhere in the good-fair range.

Is there a way to set the ring so as to help negate the effect of using these side diamonds........or any ideas?

Thanks again,
Terry

Hi Terry

The pavilion angle itself is far too steep, light leakage is going to be a real possibility and colour entrapment because of this one measurement, well cut diamonds do not have such steep pavilions whichever way you look at it....You say you have ordered the diamond already?
 
I have not bought it yet. Thanks for the input.........so as far as the cut grade goes on the GIA cert, should I be really looking at the crown/pav angles, and not paying attention to the grade so much?

Thanks,
Terry
 
play with the cut adviser.

Keep the tables below 60% and total depth below 62.8% and with a score of 2 and lower should be a good candidate to further investigate with Idealscope/ASET image.

Ditto that, personally I would keep depths for the type of diamond you are looking for to no more than 62.4%, table as said maximum 60% and keep HCA scores between 1 and 2 initially for ring stones, then always evaluate with images if possible.
 
Ok.....thanks again for all your help!

One last question..........I did have an alternate, however it was an SI1 clarity...thoughts compared to the previous diamond:

.92 ct
H
SI1
Excellent cut
Depth: 62.1%
Table: 56%
Crown angle: 35.0 degrees
Pavilion angle: 40.8%
pav depth: 43.0%
Polish: ex
Sym: ex

clarity characteristics: Feather, Cloud

Thanks again everyone for all your help!

This one is a definite improvement, see if the vendor can get you an Idealscope image of the diamond. Also check the diamond is eyeclean to your specifications and that the grade making cloud isn't affecting brilliance, this is unusual in SI1 but best to check. Do you have the girdle thickness and the diameter too please? Also if you can post the star and lower girdle facets too that would be helpful, these will be on the diamond diagram.
 
Numbers look promising. Ditto the numbers and Idealscope images. Also ask if it is eye-clean.
 
Girdle medium to slightly thick: 3.5%
on the diamond gia cert next to the girdle specs it says 75%
measurements: 6.20 - 6.23 x 3.86 mm
Also it has an inscription that says H&A.........im assuming this is hearts and arrows...and that is a good thing?

I might just go with one...........but am concerned of the "cloud" since the bottom half of the cert is cut-off, not showing where the inclusions actually are.....

Seems kind of shady to me..............I found it on diamondsonweb.com. I guess with a return policy it doesnt matter, when I get it, if it doesnt look good to my eye, I can always return it.

thanks again!
Terry
 
Looks promising.

That looks like a diamond quality dossier type report which will not have a clarity plot.

The H&A comment is just GIA reporting that 'H&A' has been inscribed on the stone's girdle, it does not mean that GIA verifies the stone is a H&A. A verify H&A means that it has excellent optical symm with proportions that creates hearts and arrows images when viewed with a special viewer.

What is the budget you are working with? Maybe we can find something better with images?

Ditto. Also if you would like us to try to find you something then we can certainly take a look for you?
 
I am looking to stay under $4000 for the center stone.........and a stone .90ct or greater.

So, obviously, I have to sacrifice somewhere. I have decided to go for best cut possible.......and stay in the H range, SI1.

Does like seem like a good compromise?

Thanks,
Terry
 
Lorelei,

That would great............like I said, my budget is $4000, would like to stay at least in the H color range, SI1.

Biggest concern is finding the best cut possible...........please let me know if you find anything, it feels like I keep going in circles trying to find a stone.

Thanks,
Terry

No problem Terry, lets see what we can come up with!
 
I totally understand sentimental attachment to diamonds, I am in no way trying to negate that!

Have you considered trying to source an Old European cut diamond that will match the side diamonds? I think that would look cool. I also wonder if you have held your side stones next to a modern RB? The facet patterns will be different, which may or may not appeal to you. I am not saying it will look bad with a modern RB, just that you should make sure you like it before finalizing things.

How large are the side stones? Approx. mm width?
 
Hi all,

Thanks again for all the help............in response to dreamer''s reply, I have not tried to source a european cut, only because I wanted the center stone to be as brilliant as possible, and from my understanding.....inherently due to the technology used back then with EC''s, they are generally not as brilliant. With a $4000 budget, I doubt I''d be able to make up that difference by getting the "best of the best" euro stone.

I guess my main concern lies with mounting the center stone due to it''s size. With two appx. .70 ct side stones........I am very concerned that a .90-.93 center stone is not going to be big enough to overcome that look of an anniversary band. I was actually told by one jeweler that I''d be a "moron" to only go with roughly a 1/4 ct higher for the center, that it would undoubtedly not look like an engagement ring. Obviously, it would serve him well to have me buy the largest stone possible....but couldnt help being a little concered.

I know obviously being within a $4000 budget and wanting an H, SI1, best cut possible narrows the field quite substantially. Any thoughts on how to mount the stones in order to make it look more like a traditional "engagement" ring while using the side stones?

Thanks..
Terry
 
What is the diameter of the 2 european cut you have?
 
I''m not sure of the diameter, I havent really gotten them checked out except to drop them off to jewelers to get them matched. I''m probably going to bring them somewhere to get the specs so I can have a better idea.
 
Matched in terms of color to a center stone I mean..............none of the jewelers I went to were way overpriced, so I came online to search for the center.
 
Those proportions will not give much contrast, but maybe who cares? It would still look good and blingy.
