Split Shank vs Cathedral Setting
By Clint Casmiro, Co-Founder, Smiro Studio, Toronto · Updated September 28, 2026
Short answer: A cathedral setting has the band rise up in two arches to meet the head, then stop. A split shank divides the band into two strands that open up and flow into the head, so there is no end point. A cathedral looks classic and clean. A split shank looks more fluid, and with a tulip basket the band seems to grow into the petals.
Here is a 3 carat oval with a clean top view and a split shank that flows with no end point.

To start, it's this 3 carat oval diamond with a super clean top view, you don't notice anything except for the stone, and then that band. Only when you flip the ring over do you see this beautiful hidden halo wrapping all the way around, four tulip petals underneath the oval diamond, and this super subtle split shank that opens up and flows directly into the petals. I love this split shank addition because there's no ending at all within the ring. Split shank just flows open, connects the ring head into the band so seamlessly without an end point.
The ring in the video
A 3 carat oval with a clean top view: just the stone and the band. Flip it and there is a hidden halo wrapping all the way around, four tulip petals under the oval, and a subtle split shank that opens up and flows directly into the petals.
Cathedral: rises and stops
The band arches up on each side to support the head. It is strong, classic and lifts the stone. From the side it ends where it meets the basket.
Split shank: opens and flows
The band splits into two strands near the head. There is no ending: it connects the head and the band in one line. With a tulip basket, it looks like the flower grows out of the band.
Which should you pick?
- Want classic and clean: cathedral.
- Want flow and a little more detail: split shank.
- Want a subtle version: a split you cannot see from the top.

Is a split shank or cathedral stronger?
Both are strong when built properly. Band thickness matters more than the style.
Can a split shank have a wedding band sit flush?
Yes, if designed for it. See flush bands.
Can I combine a cathedral and a split shank?
Yes. A cathedral that splits near the head is a common hybrid.
How much does a split shank or cathedral ring cost?
A fully custom ring from us starts at about $4,000 USD, and most of the rings we build land between $4,000 and $5,000. Our Ready To Order settings start at $1,299 CAD, plus the diamond. The centre stone moves the price most: in September 2026 a 2 carat lab grown diamond ran about $2,500 CAD and a 3 carat about $2,700 CAD. Real numbers are in our cost guide.
Does a split shank make the diamond look bigger?
It can make the head look wider from the side, and the extra metal frames the stone. From the top the difference is small.
