What Is a Baby Split Shank? The Detail You Only See From the Side

Table of Contents

    By Clint Casmiro, Co-Founder, Smiro Studio, Toronto · Updated September 27, 2026

    Short answer: A baby split shank is a band that splits into two just before it reaches the setting, then flows up into the gallery rail or the tulip petals. The split is small and thin, so you barely notice it from the top. When you turn the ring to the side, you see a tiny split in the profile. It is a subtle way to personalize a ring without changing the top view.

    One personalization worth knowing about when you design your ring. This one was set with a cushion diamond.

    What is a split shank?

    The shank is the band. A split shank is a band that divides into two strands as it approaches the centre stone. Traditional split shanks split early and wide, so the gap is a big part of the ring's look from the top.

    How is a baby split shank different?

    It is much smaller. The band only opens up right at the side, then flows into the gallery rail, the tulip petals, or whatever sits under the stone. From the top view you would not even notice it. From the side you see that little split in the profile.

    Our split shanks are cut small and thin on purpose, so they add detail without making the ring look busy.

    Why choose one?

    • It personalizes the ring without changing the top view.
    • On a tulip basket, the split flows up into the petals much more naturally than a band that just stops at the head.
    • It adds a little architecture to the side profile, which is the view people see when your hand is resting.

    Does a split shank change the band width?

    It should not make the band thin. We never go under 2 mm on a band, split or not, so the ring stays strong. More in our band width guide.

    Does it work with any stone?

    Yes. The one in the video is set with a cushion, and our moval six petal tulip pairs one with a hidden halo. Like any detail at the bench, it adds a little time to the build.

    A band that splits into two just before the setting and flows into the gallery or petals. It is subtle from the top and visible from the side.

    Is a split shank noticeable from the top?

    A baby split shank is barely noticeable from the top. A traditional split shank is wider and much more visible.

    Not if the band is built properly. We never go under 2 mm on a band.
