Structure Integrity - Cathedral Setting

[blh0687]

Hello,

My fiancé had the below cathedral engagement ring designed for my 1.7 carat diamond. When the CAD design was shown to him, he questioned if the base of the cathedral (the part that would rest on the top of my finger) needed to be thicker, and he was told it would be fine. When the actual ring was shown to him, he questioned the same thing again and got the same answer. When I received the ring from him, I questioned the same thing.

The ring is being sent back to be remade as they made the ring too small. Should I be concerned about the ability of my ring to hold up over time due to the thin band at the base of the cathedral? Could it wear? Is it at risk of deforming if it would experience pressure? If so, I’ll make the request for that portion to be thickened when remade.

Thank you in advance!

It doesn't look thin at all to me... it actually looks to have a quite hefty shank.

Thank you for your response. Is it just the outer most edge that I need to be concerned about for stability or is the portion under the scrolling (creating the circle my finger will be in inserted into and touching - above black line) need to be thick as well to give the ring proper support?

No, that ring looks strong due to the thick metal that supports the thinner metal. The setting is fine.

Do you have a photo showing the thickness of the underside?

I would worry about the daintiness of the thin band that rest on top of your finger. All that metal
work under the cathedrals looks thin like if you catch it on something and pull it may give way
(lets hope that never happens). I would treat this setting very gingerly.

Sure, any filigree work is subject to being pulled out of place, but what about the band she was asking about? All we have is one angle, so it could be that it's thicker when viewed from underneath, no?

You can see the thickness of the band that goes around the top of her finger (or I should say
thinness). Even if it is 3 mm wide which I doubt it is, the thickness from the side is still very thin.

blho698...do you have the CADS you can post so we can see the thickness of the different parts of
the ring. How wide is the main shank of your ring (the heavier part of the shank)?

 

[blh0687]

I appreciate the feedback! The band resting on my finger isn't thick, but it is the full width of the ring (top picture). However, the scroll work is fine; there is a this loop on each side with a gap in between (bottom picture).

tyty333 - no dimensions were received. This is what we were given.

The basic structure appears to be okay, and the thick shank would protect against the ring getting knocked (and it will get knocked because from the photo it looks like it sits high because of the filigree underneath even though the CAD looks like the basket wasn't supposed to be any higher than normal, just the cathedral would be). I agree with TyTy though that the biggest risk is snagging the filigree on your clothing. There are multiple open loops on both rings. And if the ring sits higher than usual, the chance of snagging is increased. I'm not sure the structural integrity of the ring itself would be affected, but if the filigree got pulled out of position it wouldn't look very good and might be impossible to wear if the filigree was really out of position.

Agree totally... and no "thickening" of the band portion will change this.

At least the band does look wide (you can measure it if you have a ruler with mm on it). Personally,
I would want it thicker but I would have to see CADs to see how it affects the aesthetics of the setting.

What is going on where the shank hits the head of the ring? I thought I could see a bar in your real
pictures but I dont see it on the CADs. Is there milgrain on the side of the shank (the cathedrals)?
I dont see it on your ring but it is in the CADs. I probably just cant see it at the angles you've posted.
Can you post a top down view and a side view of your setting (not the shank side...but the view where you put your finger through the hole.)
