Round One, Baby | Solitaire Engagement Ring

A classic with a wink. Our round-cut solitaire is all glow, no fuss. A lab-grown diamond held in a clean four-claw setting that lets the light do what it does best. Think forever energy with modern polish

All stones above 0.30 ct come with an official certificate.

Our lab-grown diamonds are graded by the International Gemological Institute (IGI), the global authority on laboratory-created stones. Each certificate details cut, clarity, color, and carat, giving you complete confidence in your jewel.

For natural diamonds, available only on special request, we provide certification from the Gemological Institute of America (GIA), the most trusted name in natural diamond grading.

Every certificate is a promise of authenticity, integrity, and lasting value. Your sparkle is not just claimed, it is certified.

Your Stacked&Co jewel is made to shine for a lifetime, but a little care goes a long way. To keep its brilliance, avoid harsh chemicals, remove your piece when swimming or exercising, and store it safely in its box when not in use.

Clean your diamond gently with warm water, mild soap, and a soft brush. A quick polish with a lint-free cloth will restore its glow between wears.

You can also send your piece back to us for a complimentary professional clean. Shipping is at your own cost, and we will take care of the rest.

With the right care, your jewel will stay as radiant as the day you first stacked it.

Each Stacked&Co piece is crafted to order by skilled artisans, ensuring every detail is finished to perfection. This process allows us to reduce waste and create a jewel that feels as personal as the moment you choose it.

Please allow up to 3 weeks for your piece to be made before it is shipped. True luxury takes time, and your ring is designed to last a lifetime.

Crafted with intent. Delivered with care.

Our products are crafted to fit true to size, ensuring that you can confidently select your usual size with ease. Whether you’re looking for a relaxed or tailored fit, our designs are made to complement your unique shape and style.

Your jewel should feel as individual as the moment you choose it. With Stacked&Co you can customise metal, diamond shape, and carat weight to suit your story.

If you’re dreaming of something even more personal, our designers can help you create a bespoke piece — from a subtle tweak to a completely custom setting.

Every detail is crafted to reflect your taste, your rituals, your style. This is jewelry you don’t just wear, you make it yours.
