CAD Advice: OEC and French Cut Diamond Ring

[Paisley2628]

I am attempting to create a new ring with diamonds that I currently own. The OEC is 7mm x 6.9mm. The French cut diamonds are currently set in a band, so I can't get an exact measurement. I think they are over 3mm - maybe 3.3 or so.
I'm not sure if the proportions of the OEC to the French cut will make for an attractive ring. I'm guessing there are many things on the CAD that I'm not seeing that would cause a problem. I would like to keep an overall "cushion" outline for the ring.

I would greatly appreciate all thoughts/advice/concerns regarding the CAD. The CAD is a first draft, so I'm sure there will be changes! Thank you!!!

I would be very wary of tweaking a cad /falling in love with what I see
Until I knew the exact size of the FC and it was represented in the CAD correctly.
Just my 2c.

Are you going to be ok with almost doubling the size of the center stone?

 

[Rfisher]

Also -look at your center stone depth of 6.9 compared to the depth measurement of the ring head on the CAD of 5.92

just something else to think on

The dimension of the face of the OEC is 7mm x 6.9mm (not perfectly round). The depth isn't 6.9

I didn't initially state that correctly - and caused confusion

Oops! I’m sorry!

I am looking for a "bling" ring - I'm good with a large diameter in total.

It would be preferable to have smaller French cuts, or a larger center stone. I really wanted to create a ring with the diamonds I currently own.

I think it’s lovely!

This.
No use nitpicking a CAD if the stones aren’t accurately reflected. Nuances make all the difference. I’m honestly quite surprised that the vendor offered CAD effort without evaluating the stones - there’s likely to be quite a bit of wasted time on their side too.

Thank you-
The French cuts aren't loose - they are set in an existing ring. I wanted to see a CAD of what the new ring may look like before the original French cut ring would get taken apart.
If the CAD wasn't attractive or doable, I wouldn't want my original ring destroyed for no reason.

Thank you!
I'm trying to create a new ring with diamonds I already own in order to have a pretty ring without spending $$$.

I'm guessing most folks aren't liking the drawing

I'm not an artistic person, and I haven't seen any ring with similar diamond proportions in any of my searches- so I did the best I could for the design.

@Paisley2628
I apologize.
I do like your design idea.
I do like the basic idea of utilizing stones you already have.

I do know what it’s like to fall in love with the belief /promise of a CAD’s literal outcome.
whether it changes due to the size/shape of the actual stones to be used or whatever - and the end result not really resembling the CAD at all.
I know - but that’s not a story for now.

which -in my opinion - if you are asking for tweaks/suggestions for the design now
And then the scale of the design noticeably changes after the actual size of your FC is inserted -
Whether you are advised of those changes before the ring is produced/finished or possibly even not.

all the thought that’s taken tweaking and looking at detail/proportion is for naught - why put yourself through that now?

I absolutely understand the preliminary ‘I have an idea - will it work/suss out on paper - the vendor is willing to do so - so why not?’

asking for design tweaks right now, without knowing an integral piece of the design size - I don’t understand this.

I’m sorry. I inserted my feelings and a past experience into your question and that was unnecessary.

edited to add: and yes, I did resurrect your preloved thread for your FC band. And I explained the reasons over there.

I just don’t really understand what you’re looking for from us. Not a judgment on the design itself.

You said in your original post that you aren’t sure if the proportions of french cuts to center will make for an attractive ring.
It’s impossible to know what those proportions will wind up being - and decide how you’ll feel about them - until you have precise measurements on the french cuts.
But you don’t want to pull the french cuts out of their current mount until you decide you’ll like the new ring.
The exact size of the french cuts will determine size and number of corner round melee, width and curvature of bright cut channel, amount of negative space under the cushion outline corners, proportion of halo to centerstone - all of which may greatly impact how you feel about the design.

So short of getting 5+ CADs for variously proportioned french cuts and/or committing to recutting the french cuts if they’re larger than your desired aesthetic allows for - this topic is a bit of a catch-22.

OP, can you send the ring with the french cuts to DK and would it be possible for him to remove one to measure it? Assuming they are all the same size, removing one should be sufficient to know the size. I don't know how they are set, but perhaps he could remove it and if it doesn't work out, reset it in the band?

I agree, but feel the unmounting and possible remounting of her particular ring would be a (relative) costly affair to do right.

I'm guessing these are the french cuts you want to use? Probably not as easy to remove and replace as it would be if they were prong set. I was just hoping.

I found these two inspo pics for you-I know that the portions are off…Is this the approximate look you are going for minus the air lines?

I think the ring will be lovely if you can get the portions correct.



(these rings probably belong to some lovely PSers but I just pulled the images off of google)

 

[yssie]

The original band is really lovely - and those french cuts do look sizable.
@Paisley2628 what do you think of this preliminary design? Would you wear a ring like this more than the original band?
It will have a large profile on your finger, which is not large.

 

[molecule]

they are over 3mm - maybe 3.3 or so

I'm going to be a dissenting voice. Regardless of the exact measurements, I wouldn't like it. The proportions of two 3mm side stones in a halo for a 7mm center stone seems off to me.

I'd like them as part of a three stone or in a separate piece, maybe a bangle, drop earrings, or a necklace.

 

[Lookinagain]

I think the proportions in the CAD are fine but I think your stones may be larger than the 3mm used for the drawing. French cuts are usually pretty deep. Yours are probably .25ish ct. each. But without removing them from their setting you just won’t know if they are too large for your design and center stone.

 

[ksluice]

I love the examples @lulu_ma found, but I also lean towards what @molecule is saying. I wonder if your 7mm center stone, may want a more narrow halo than the 3mm carres you have will allow for. (FWIW my avatar stone is about 7mm at the center, and it seems to me the examples are similarly at 25% of the center stone at their widest). The other thing I might think about is whether the stones on the NSEW axis may want to be something more like the baguettes or the nifty trapazoids in the VC ring, to balance the motion around the halo with the cross action the NSEW stones create. That cross is a very powerful move, particularly with a center stone that is more round, although your designer is doing some interesting things to soften it by moving the line created by the round stones to the edge and creating the mini-air lines at the corners. It’s hard to know how much balance that x is giving to the cross because the colors in the CAD add their own geometry. I mean, there is nothing wrong with creating a design that has a really predominant NSEW cross, but you want to know that is an effect your creating. it would be something I would want to think about, in any case.

 

[diamondseeker2006]

I wouldn't remove those french cuts from that ring. I'd certainly sell it as is. It's a beautiful ring.

Then have DK source the correct size french cuts or carre cuts for your setting. I like the setting design a lot. I just wouldn't take apart a beautiful antique ring to do it.

That said, if you really want to use the french cuts from that ring, it needs to be sent to DK so they can figure out the actual size before even considering revising these CADs. If they are ANY larger than those CADs above show, they would be too big, IMO.

 

[LightBright]

Wait, if this is your F color antique French Cut ring, I’d definitely think twice about ripping the ring apart. This is just my opinion. The F color relatively large French cuts are really pretty. My concern is that the color and relative size of the French cuts might overshadow the center OEC. Ring might look like a hodgepodge.

I wonder if you could do this design (which I love) with stones that fit the scale of that OEC and that design. I like the current CAD. I even like the idea of sapphires with the OMC at this scale.

I come back to your F color large (rare) antique French cuts all in a row, in a setting that is intricate and special, that was made for them. I’d keep that ring intact as IMO the value is more in a whole, undisturbed piece.

To me, I would execute this design for your OEC, which I like a lot. But I’d find separate square cut stones.

 

[Paisley2628]

Thank you all for your responses-
I guess the thing is, I love the French cut diamonds, but I don't love wearing it as a band ring.

I was attempting to make due with what I have - based on a limited budget (which is what I've always done) to create something new.

 

[yssie]

So what do you think of the prelim design? Do you think you would wear something like this more than you wear the band?

Why do you not wear the band - have you been able to identify any specific reasons? That really helps tailor future projects - in terms of what to avoid.

 

[distracts]

Yeah I agree with everyone else that it's hard to give advice when the proportions may change. I personally would like it even if the French cuts were quite large and created a more obvious cross effect/cluster ring effect, but not everyone would.

What color is the OEC?

 

[Rfisher]

Would you be willing to show a photo of your OEC that details the faceting pattern, next to your FC band?
What were you envisioning using for the melee? Single cuts or brilliants?

I would prefer using single cuts - to keep with the vintage look. I'm not sure if brilliants mixed with old cuts would work.

Almost all of my diamond purchases were from Ebay finds. I have never purchased a GIA diamond with paperwork. I spent a lot of time on Ebay in the past searching for items that I could afford. I was never in a position to choose faceting patterns that I fell in love with. Honestly, I was just happy to have been able to purchase OEC diamonds.

Here are some photos:

You have asked some good questions!

If I had a dream ring, it would actually look a lot like the ring photos that @lulu_ma posted earlier in this thread.

Is the prelim design a dream ring? No, its not. But it allowed me to use what I already own.

I don't wear the band because at my age, I'm looking for something with more presence. For example, I sold a lot of my more "dainty" jewelry, and purchased some VCA pieces that I adore wearing.

I love the French cut diamonds that are in the band. If I could use them to create something with more impact, I would like to do that!

What color is the OEC?

The diamond was already set in a ring, and it was sold to me as a K color. It is not a GIA diamond- I don't have any paperwork on it.
