The Keeper – Blue Diamond Edition

For those drawn to the light and the sea that surrounds it.

The Keeper Blue Diamond Pendant reimagines the spirit of the lighthouse through the color of the ocean itself. At its center rests a vivid lab-grown blue diamond, its hue reminiscent of the deep Atlantic — calm yet powerful, rare yet enduring.

Each emerald-cut stone is certified and set by hand in 14k gold, framed in Cove Fine Jewelry’s signature design that balances refinement with meaning. Just as the sea reflects the sky, this pendant reflects the bond between light and water — a modern heirloom for those guided by both.

Available with or without a chain. Each piece is designed on the Seacoast of New Hampshire and crafted in New York’s Diamond District, where artistry meets authenticity. Designed with a sense of place and connected to New England roots.

IGI Certified

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. Pearls, on the other hand, are more delicate—they should be kept away from sunscreen, perfume, and hairspray to maintain their natural luster. 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.
