100% Satisfied

I was nervous about buying a ring online but it seemed like it would be a wild goose chase trying to find an elongated hexagon moissanite engagement ring (which is what my now fiance wanted) so I took a chance with Brilliant Carats and I'm glad I did. The ring is high quality and the price can't be beat. I will be shopping with them again for a wedding band.

Light That Moves Beyond the Center

Side stones create a visual transition from the center stone into the band. This added rhythm gives the ring greater presence without taking attention away from its defining shape.

Frequently Asked Questions

What are the benefits of a side stone engagement ring?

Side stones add light beside the center stone and create a smoother visual transition into the band. They can make the overall composition feel fuller and more balanced while keeping the chosen center shape as the main focus.

What is the difference between a side stone and halo engagement ring?

Side stones sit beside the center stone or continue into the shoulders of the band, creating movement across the ring. A halo surrounds the center stone and strengthens its face-up outline. Some designs combine both details for a more layered effect.

Is a side stone ring the same as a three-stone ring?

A three-stone ring is a specific side-stone arrangement with two prominent stones beside the center, often representing the past, present and future. The wider side-stone category also includes smaller accents, pavé shoulders, clusters and twisted settings.

Are lab-grown diamonds real diamonds, and are these rings IGI-certified?

Lab-grown diamonds have essentially the same chemical, physical and optical properties as natural diamonds but are created in a laboratory. Selected options include IGI documentation, which may apply to the diamond or finished jewelry depending on the product. Some designs may also offer moissanite options.

How are side stone engagement rings made and delivered?

Most styles are made to order in 7–10 working days. The final delivery includes photos documenting how the ring was made, while free shipping is available to most countries. Check the individual product page for its exact stone, certificate and production details.

What makes your lab grown side stone engagement rings eco-friendly?

Our lab grown side stone engagement rings are created in controlled environments, avoiding the environmental damage associated with mining. They use less water and energy and have a smaller carbon footprint, making them a conscious choice for modern couples.

Flanking Stones, Pavé and Twisted Lines

Choose distinct stones beside the center for stronger balance, pavé shoulders for a continuous line of light, or twisted details for movement. Pear, oval, hexagon and other center shapes respond differently to each arrangement.
