Guess the size of the Bullet cuts on this vintage Cartier 3 stone

[e2the3rd]

Hi all - say hello to my dream ring!

I really hope to recreate it in the near future… but first I need to know the approximate size of these unique wide & short bullet cuts, so I can get a price quote and know how much I'll need to save up.

Assuming the center 2ct OEC is somewhere close to 8mm, what do you think the bullets are in mm? Are they about the same length as the widest point width?

I know some of you are great at this type of thing - thank you!

Center stone would be around 8.1mm, so maybe 60-75% of that diameter for each tapered bullet?

Yup, that's exactly how I would try to calculate if I were you.

I get the goal- of trying to budget...they'll be expensive- that you can count on

Seriously- once you have a center in hand, you can better work with your vendor to source appropriate side diamonds, based on the availability.
The bigger consideration, from my experience, is that specialty side stones are difficult ( or impossible) to order in exact sizes. Rather, you need to see what's existing and work with it.
So, even knowing the exact size won't move you any closer to actually recreating it.

PS- they will also need a custom made ring

@DejaWiz @lovedogs
Any thoughts about the length?

I appreciate that, just want to be able to request a ballpark estimate from my vendor whom I’ve been in touch with, without having the designer start creating cads. Vendor has someone who can do custom cuts. If the custom cuts are too much over what I’d care to pay, then I’ll go with something already cut that’s out there, and I’ve already saved some options I think are close enough. Doesn’t need to be exact, but I do want similar proportions so I thought I’d reach out here for suggestions

Might you precision-focused, custom project veteran lovelies care to take a look and weigh in, pretty please?

measure em in the picture then use that as a ratio.
say you get 10mm and 7mm then 7/10 = .7
so your center diameter x .7 gives you the size for the same ratio

From my experience: It's crazy costly to custom cut any diamond. Even knowing the outcome of what color/clarity a given piece of rough will polish to .... that's a huge uncertainty- and in the case of side stones, you really need things to match.....
Not to be discouraging....just realistic

Good to know. Thanks so much

While I'm not going to argue with David as he has been there done that, it dont hurt to ask just be prepared for sticker shock and have an alternative plan.

I agree with @Karl_K
% method

What is the diameter of your centerstone you are basing your CAD around.
Maybe we can approach it from that route.

Thank you! My center round is 8.1mm. I was originally guessing around 4.5mm at the widest points of the bullets but from what others are saying sounds like I might want to go up. I wasn’t sure if the angle of the setting messes with the appearance of the proportions

Thanks, I also have my eye on a pair of shield cuts that might be close enough in size and will keep searching for already cut pairs

the one with the red lines will get you close enough to get the look.

bullets or shields - you’ll want clipped corners to achieve the same look as the vintage ring. At least that’s what I seem to see - clipped corners on those diamonds they are calling bullets. Quick google tells me most don’t?

angle of photos (and how they are set) is definitely a factor. I do know math is king and doesn’t lie, but
this backwoods visual way has always helped me.




Also - im sure you are aware, the WxL of these bullets are only a part of the key in duplicating the nice shape that the vintage ring bullets have.

And getting over the mental block of seeing a 2carat OEC on a probably sub size5.5 finger - that’s another issue
(sighs in size7)

I hope some of my weird ramble helps you in some way.

Thank you so much! I was trying to find apps or something to measure the digital image. Now to see if I will ever find the close-enough, not-crazy-expensive side stones that could work. .

I’ve been studying shields vs bullets and I wondered too if they listed them as bullets instead of shields, it’s tough to see what’s happening at the top edge of them but does look like there are clipped corners. Shields are triangle cut with varying clipped corner sizes and bullets are baguettes with a point at the end, from what I read

Tapered Bullets, more than likely.

@Rfisher you rock.
I was just going to hold a ruler up to the screen when I was at my computer.

 

[Lookinagain]

I'd call them shields. At first glance I thought they were cadillac cuts but looking again, I'd say a bit squatty shields.

I love your responses - you are a wizard of mockups and measurements! So creative, too.

@Lookinagain your response is perfect for your username

I have nothing to add except this is gorgeous and so unique and I’m sending you allll good vibes. Can your designer work on the CAD with this info and do a rubber / plastic mock-up?

Thank you! Yes, but first I just wanted to determine if I can find or have cut and afford the side stones... I didn’t want to request cads yet without having a good idea of the size and cost of the side stones. This might well end up being a later down the road dream ring

No I sure don’t, I think I discovered it on their Instagram after it sold

just wanted to point out the face up size of the side stones depends upon the angle they are set to the horizontal. To add a little to @Rfisher's fantastic scaling drawing; at the angle they are set the 4.25-4.50mm bullets face up at about 3.10 mm long.




You can see if those sides were set at a less steep angle, they would face up longer.

This is such a valuable detail to know, thank you! If I ever find stones and get to the design stage I know I’ll be struggling with the angles
