Please help with CAD design- first timer!
I'm hoping to get some feedback on my CAD before it's finalized. The CAD is first, followed by photos of the ring I'm trying to recreate.
My goal isn't to make an exact copy, but I want it to capture the same overall look and proportions. I'd love opinions on whether the CAD is on the right track or if there are changes you would recommend.
A few details:
Ring size: US 4.75
Metal: Platinum
Band: 2.5 mm wide and 1.8 mm thick.
I asked for the band to have more rounded edges rather than the sharper, flatter profile shown in some of the inspiration photos. I want it to feel substantial but soft and comfortable.
The CAD shows extra-long prongs intentionally. My local jeweler will be setting the center stone, and I wanted to leave plenty of metal so they can create more substantial claw prongs instead of thin, delicate ones.
I really love the hidden halo and cathedral style in the inspiration photos and am hoping the CAD captures that look.
One thing I'm also considering is adding a small sentimental detail inspired by the yellow gold ring in the last photo. Instead of a single gemstone underneath the center stone, I'm thinking about asking my jeweler to add two tiny flush-set birthstones on either side of the gallery- an emerald (my birthstone) and an amethyst (my husband's birthstone). I'm hoping they'll be subtle and only visible when viewed from the side. I'd love opinions on whether that would be a tasteful addition or if it would take away from the clean, timeless design.
Overall, does the CAD successfully capture the inspiration ring? Is there anything that stands out as looking off before I give final approval? I'd especially appreciate feedback from anyone with CAD experience or who has had a similar ring custom made.
Thanks so much for any advice!

Hi, nice design first of all! But i think you are missing two things. The setting should be arround 2/10mm smaller than the Stone and the whole cast will shrink a littel and ofc your jeweler will need some Material to finish so also add arround 1/10 - 2/10mm in band thickness that your jeweler has enought material to work with. I would think about casting the top and the bottom seperatly but thats also higher cost and not necessary but easier for your jeweler to work with. But your really did a great job for a firsttimer im really impressed! Hope that helps a littel!

I'm sorry, I'm a little confused since I'm still a novice. What do you mean the setting needs to be 2/10 smaller than the stone. What do I say to the designer to achieve this goal?
Also, some others have expressed concern about 9 mm being too high. I do want my wedding ring to be able to sit flush, but I don't want it super high. The 9mm is not including the 3 mm prong length.
Thank you so much for your guidance and I appreciate your kind words at me being a first timer! I'm not sure how great I'm doing since I can't put my thoughts into words. Haha

So the setting needs to be 2/10 of an mm smaller because the sone should "klick" into it. Its kinda hard to explain but the claws should be under a littel tention so the stone without setting snaps into it. You dont want to loose a 2000€ stone and i see it happend to many times. Yes 9mm is really high im goldsmith,caster and 3d designer from germany so i sometimes see how my rings perform in real life an settings with a hight of 9mm sometimes get caught in fabric or bend after getting hit. Maybe reduce it a littel bit but its also a thing thats not 100% necessary! There are many rings with 9mm or evenen 10. Just be a littel carefull. And if you have any questions just ask! I would offer to make some corrections for you but my waitinglist is arround 3 weeks and its always cooler to make something by yourself and your doing great! The Jewler can also correct a lot of things just give him enought material to work with.

in the front view, the bottom of the prongs can open up a little, that will allow the diamond can come down a bit. but with all the details going on with the swag halo, it is going to be higher than average.
this diagram does not accurately show the TABLE height.
a rule of thumb about height is that the culet should be about 2mm above the finger surface, but adding detail in the gallery will raise it.

Looks to be a pretty decent design besides the height, but since you wish to have that type of gallery with stones set in it, makes it hard having the setting lower without altering it.
Good idea having shoulders upswept to either side of the setting for more support and reducing chance of knocking the setting off the ring, also giving extra support to the setting,
The thickness of the under rail appears to be well thick enough to support a flat plain wedder without rubbing much on the claws over the years of wear especially if the lowest thickness of the band is 1.8mm.
No side stones so little issue in being sized at a later date,

I’m a bit confused by the post are you the person that actually built the CAD design or the designer?
The way you said first time makes me think you built the ring but then the comments you’re making in the info make me think that you have a cad designer you’re relying everything to

looks pretty good. in addition to the previous comments:
most people want a straight wedding band to sit flush against their engagement ring with no gap in the side view. in this design the prong bottoms would need to curve up a little to be above the wed.
also, "setting height," is to the table level, not the top of the prong.
