Inspired by the Coast. Designed for Forever.
Every Cove engagement ring begins with a sense of place—from the beaches of Cape Cod to the rocky shores of New England. Our signature settings are thoughtfully designed to capture the effortless beauty of the coast while creating heirlooms made to last for generations.
Ethically Crafted with Lab-Grown Diamonds
Lab-grown diamonds are chemically identical to mined diamonds and offer exceptional value, allowing you to choose a larger, higher-quality stone without compromise.
Each ring is made with premium lab-grown diamonds that offer the same optical, chemical, and physical properties as mined stones — with a smaller environmental footprint.
Our master jewelers hand-finish every setting to ensure exceptional symmetry, comfort, and longevity. Made in the USA.
Are Lab-Grown Diamonds real diamonds?
Yes. Lab-grown diamonds have the same physical, chemical, and optical properties as mined diamonds.
Care Guide
To preserve its timeless beauty, solid gold is naturally resistant to the ocean’s elements, while pearls should be kept away from sunscreen to maintain their luster. Diamonds and gold may be safely cleaned in ultrasonic machines; however, delicate gemstones and pearls require a gentler touch to ensure their brilliance endures.
To clean gold jewelry, use warm water with detergent-free soap and a soft brush, then polish with a jewelry cloth. Store in a soft bag or the original box to prevent scratches.
