Hundreds of Couples Have Trusted Cove

  • Alyson helped me customize this ring for my proposal. She was extremely helpful from start to finish, and provided multiple options to guide me to the perfect ring. She is very knowledgable and quick with communication. The ring arrived in secure mail with no issues. My fiancé was very happy with the ring and we highly recommend using Alyson and Cove for any jewelry purchases!

  • This ring is everything I always imagined my engagement ring would be. I am beyond thrilled with the quality and craftsmanship of it. I waited a long time to upgrade to this ring so when I was ready for it, I was ready ASAP. The whole process of working with Cove was quick and seamless. I couldn't recommend this ring (and all of the Cove pieces I've bought now) more! I've only worn it a few times and already lost count of the compliments. This ring feels so special! Thank you!!

  • Alyson did an amazing job making my dream ring come to life! She worked so hard with my fiancé to get it just right! She communicated with us throughout the whole process to make sure we were getting exactly what we wanted.

  • The entire experience was 10/10! Working with Alyson was so nice, the ring is absolutely stunning! I’ve been wearing it for months and have gotten so many compliments. I love that it’s a woman owned brand and made here in the USA. That doesn’t come often anymore. Can’t wait to get more Cove pieces!

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.
