Details

The Swell Cushion Cut Three-Stone Lab-Grown Diamond Ring is Cove’s modern interpretation of a classic three-stone diamond ring. Three cushion-cut lab-grown diamonds sit side by side, creating a substantial sweep of brilliance across the finger with the softly squared shape that makes the cushion cut so distinctive.

Choose between two proportions: approximately 2.25 total carats with three 5 mm diamonds or 3.50 total carats with three 6 mm diamonds. Each ring features EF color, VS1 clarity lab-grown diamonds selected to create a bright, cohesive trio.

The cushion cut balances softly rounded corners with brilliant faceting, giving the Swell a look that feels less traditional than a round three-stone ring while retaining plenty of diamond presence. Each stone remains visually defined within the setting, creating dimension rather than the appearance of one continuous surface of diamonds.

Available in solid 14k or 18k yellow, white, or rose gold, the Swell offers six metal options to make the design your own. Wear it as a three-stone anniversary ring, milestone ring, right-hand diamond ring, or a significant piece of fine jewelry chosen simply because you love it.

Part of Cove’s Saltwater Collection, the Swell takes its inspiration from the movement and light of the New England coast. Each ring is made to order, cast and handcrafted in the USA.
Why You'll Love It

Three beautifully matched cushion-cut diamonds create impressive finger coverage while allowing each stone’s softly squared shape and brilliant faceting to stand out. With two carat weights and six gold options, the Swell can feel distinctly yours while preserving the meaning of a classic three-stone design.

The Cove Fine Jewelry Experience

Care Guide

Cove Fine Jewelry Care Guide —

To preserve its timeless beauty, solid gold holds up well to daily wear, including exposure to water, but should still be rinsed after contact with salt or chlorine.

While diamonds and solid gold can be safely cleaned in ultrasonic machines, pearls and softer gemstones require a gentle hand—use a soft cloth and avoid harsh chemicals to keep them shining for years to come. They should be kept away from sunscreen, perfume, and hairspray to maintain their natural luster.
