Hi – My CADs are in from ERD and I would LOVE input!!! Pictures of CAD/inspiration photos follow. Here are my initial thoughts?

  • Halo needs to be more rounded on the corners (cushion-y shape) – like inspiration picture
    Halo needs to tilt downward 25-30 degrees
    Shank starts at 2.2mm at split and tapers to 1.9mm with 1.7mm melee – Seems like it is too wide at the split? Maybe no taper?
    The “split” splits too early and the single shank should be higher up the shoulder
    Each side of the split should be narrower (it is currently the same as the halo at 1.7mm) and be more curved outward instead of a straight “Y”
    How about the donut size?

Thank you!!!!!!!!

These were my inspiration photos, the first one for the cushion-y shape only since I have a round stone.

  • Halo needs to be more rounded on the corners (cushion-y shape) – like inspiration picture Only a little bit. Keep the sharp corners like MSOP's
    Halo needs to tilt downward 25-30 degrees I agree.
    Shank starts at 2.2mm at split and tapers to 1.9mm with 1.7mm melee – Seems like it is too wide at the split? Maybe no taper? Agree
    The “split” splits too early and the single shank should be higher up the shoulder Don't agree
    Each side of the split should be narrower (it is currently the same as the halo at 1.7mm) and be more curved outward instead of a straight “Y”Agree
    How about the donut size? No comment. I don't like donuts.

Thank you!!!!!!!!

Thanks Gypsy! I have to ask, why don't you like donuts? Also, do you suggest something like 2mm for the entire shank (up to the split) instead of tapering from 1.9mm to 2.2mm? Thanks for mentioning MSOPs round in a cushion, I do love her ring!
 
I do think that I'd prefer no taper on the shank.

As for donuts. Just a personal thing. I know this is a standalone RHR so I think it definitely works. But as I just don't like them, it's hard for me to comment on the size or it.
 
Bumping for more feedback!

I agree, just so that it isn't so pointy.

I agree.

It could be just a touch narrower.

The “split” splits too early and the single shank should be higher up the shoulder
I like it as is and think it looks very similar.

Each side of the split should be narrower (it is currently the same as the halo at 1.7mm) and be more curved outward instead of a straight “Y”
Yes.

How about the donut size?
Possibly just a bit smaller.

The corners on the halo could go either way. If you want the halo to be more blended with the round shape, then make them less sharp/more curvy. If you like the look of two defined shapes, you could leave it -- it's all about the look you prefer. My inspiration ring was a JB Starr piece that had a more curved halo. When I got my ring I was a little bothered at first that the corners were sharper than the JBS's... but now I'm so glad it's a little more "square" -- I like the look of more distinct shapes. As you can see, my ring's halo is quite different... (my stone is in each one)

I agree with having the 2 melee at the split like the inspiration ring -- this would "soften" the transition a bit. I like donuts, but I do think it could be a bit more dainty. I love the ring... it will be sooo pretty!! :love:
 
Chrono - Thanks for your thoughts! The picture you added with comments was very helpful...I wish I knew how to edit pictures together and add comments like that! I hope you don't mind if I borrow it to send to ERD!!

MSOP - Thank you too! I LOVE your ring, always have! I see what you are talking about in the 2 pictures you posted with the difference in "cushion" halo shapes. With the bright-cut in my design, it gets a little more challenging, because there is already more metal than a halo like yours. So, I am trying to still have it cushion shaped but with less obvious metal in the corners like the CAD. I will have ERD tweak it a bit and go from there!
 
Tweeter,
I don't mind your sending the picture to ERD at all. I cobbled it together using MS Paint. There are other posters on PS whose editing skills are far superior to mine.
 
Thanks Chrono! I will look into MS paint!
 
I prefer a doughnut almost always, but I totally agree that the halo needs to be cushion with rounded corners. Msop's are definitely rounded corners. The ones in the CAD come to a point.
 
I really like the squared corners of the halo. Have the jeweler use a slightly larger diamond in each corner for a really nice look.
 
Dumb question alert: What is a donut? I tried to google donut and engagment rings and all I got was a woman with an actual donut on her finger :bigsmile: TIA.
 
Chrono- but don't all rings have donuts/ base?
 
Chrisan - I am not an expert but I am pretty sure a donut will extend out from the shank (you can see the round "donut" in the 6th picture I posted). Attached is a link to a ring that has no donut by VC (see the second picture for a good view). Someone will correct me if I am wrong!

Andelain - Hmm, good idea with the slightly bigger melee in the corners, thanks!!

Diamondseeker2006 - I am leaning toward the more rounded cushion shape so the round diamond blends more seamlessly into the cushion halo. Thanks for the feedback!

Everyone has been so helpful!!! Thank you!!!!
 
 
Chrisan - Yep, I believe you got it! Wanting a wedding band to be flush is the biggest reason to NOT get a donut, or have a small donut to minimize the gap. I don't know for sure, but I believe that a donut provides better support of the diamond with certain settings and carat weights (not all). Visually, I like it from a side profile perspective, but some people don't!
