A 3 Carat Marquise with Hidden Details Underneath

In this guide

    By Clint Casmiro, Co-Founder, Smiro Studio, Toronto · Updated October 22, 2026

    Short answer: From the top this is a simple 3 carat marquise on six prongs. Flip it over and the details appear: a tulip basket that runs the whole length of the stone, a diamond bridge on one side, and the tiniest split shank with a small half petal right in the middle. A clean top view with every special detail hidden underneath.

    A custom marquise ring you will never find at your local big box store.

    Why six prongs on a marquise?

    Two prongs protect the pointed tips and the others hold the sides, so the stone is secure end to end. From the top they frame the marquise without adding clutter. More shapes in our marquise collection.

    How does a tulip basket fit a long stone?

    The petals stretch to follow the marquise, so the basket runs the full length of the stone instead of sitting in the middle. More ways to set one in marquise tulip basket rings.

    What is a diamond bridge?

    The bridge is the metal under the stone you see from the side. Here one side is set with small diamonds for extra sparkle at eye level. See more in what is an engagement ring bridge.

    What is the tiny split shank with a half petal?

    The band splits just slightly as it meets the head, the smallest split we make, and a little half petal sits where the two sides meet. It is the detail you notice last. Read about baby split shanks.

    Why keep the top view clean?

    A clean top keeps the marquise the star and the ring easy to wear every day. All the personality sits on the sides, for the wearer to find. More ideas in marquise setting ideas.

    Questions we get about this

    Do the marquise tips need protection?

    Yes. A prong sits on each point so the tips are covered.

    Can both sides of the bridge have diamonds?

    Yes. One side, both sides, or one side with engraving instead.

    Will a wedding band stack with this ring?

    Yes. The split starts high enough for a band to sit flush.
