Description

The Harbor Necklace captures the quiet sophistication of Portsmouth Harbor, where historic waterfront architecture meets the ever-changing Atlantic tide. Designed as a modern heirloom, it combines timeless craftsmanship with contemporary coastal style.

At its center is a hand-selected 1-carat emerald-cut lab-grown diamond, bezel set horizontally in an elegant east-west orientation. The sleek bezel setting highlights the diamond's clean architectural lines while providing exceptional security for everyday wear. Paired with a refined baby Cuban chain, the design feels both modern and enduringβ€”equally beautiful worn alone or layered with your favorite necklaces.

Every Harbor Necklace is thoughtfully designed on New Hampshire's Seacoast and handcrafted by master jewelers in New York City's Diamond District using responsibly sourced lab-grown diamonds and solid gold. The standard 16.5-inch length is designed to sit beautifully at the collarbone, with custom lengths available to create your perfect fit.

Whether chosen as an everyday signature piece, a meaningful gift, or a celebration of your connection to the coast, the Harbor Necklace reflects Cove Fine Jewelry's philosophy of creating timeless jewelry inspired by the places we love most.

The Cove Fine Jewelry Experience

Care Guide

Cove Fine Jewelry Care Guide β€”

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 handβ€”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.
