Six Cool Girl Engagement Rings We Reviewed Before They Shipped

In this guide

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

    Short answer: These are client rings we reviewed before they shipped. A round diamond on six claws over a tulip basket. A crushed ice cushion with pink, yellow and blue sapphires hidden under the stone. A marquise with leaf engraved prongs and a double band. A round tulip with the softest curved gallery rail. And a big radiant with a tulip, split shank and hidden halo, paired with an oval eternity band.

    Here are extremely unique cool girl engagement rings you probably won't see again.

    Six cool girl rings before they ship Watch on TikTok

    1. A round diamond with a tulip basket

    The most classic of the group: a round diamond on six claw prongs with a tulip basket under the whole ring. Simple from the top, floral from the side. More on our tulip baskets page.

    2. A cushion with sapphires hidden underneath

    A crushed ice cushion with natural sapphires tucked under the stone: pink on one side, yellow in the middle, deep blue on the other. The colour does not travel up to the top, so it stays hidden. Our favourite of the six. See sapphires in tulip basket petals.

    3. A marquise with leaf engraved prongs

    A traditional setting with prongs engraved like leaves, on a double band running all the way down. A more modern take on a marquise. Read about leaf engraved prongs.

    4. A round tulip with a curved gallery rail

    Four claw prongs and a tulip basket, with the softest curved gallery rail. No sharp points, it bends and flows out of the split shank. More in what is a gallery rail.

    5. A radiant with an oval eternity band

    A big radiant in the center with a tulip basket, split shank, a curved gallery rail and a hidden halo. It is paired with an oval eternity band, so radiant and oval diamonds mix across the set and stack well together.

    What makes a ring feel cool girl?

    A detail you only find when you look closer: hidden colour, engraved prongs, a curve where you expect a straight line. The top view stays wearable and the personality sits underneath. More ideas in unique ring ideas from real client rings.

    Questions we get about this

    Can I mix shapes in a wedding set?

    Yes. A radiant center with an oval eternity band is one of the sets in this video, and the mix stacks well.

    Do hidden sapphires show from the top?

    No. They sit under the stone, so the colour only shows from the side.

    Can I order one of these rings?

    Each one was made for a client. We can build something in the same spirit around your own stone.
