Details

The Hydrangea London Blue Topaz & Green Diamond Pendant captures the layered blues and greens of the Cape Cod coast in an unexpected fine-jewelry palette. At its center is an 8 mm AAA-quality checkerboard-cut London Blue Topaz, chosen for its deep ocean-blue color and dimensional faceting.

A halo of fourteen lab-grown green diamonds surrounds the center stone, introducing a softer sea-glass green against the saturated blue topaz. Together, the gemstones reflect the shifting colors of Pleasant Bay and the hydrangeas that bloom throughout Cape Cod summers.

Crafted in precious metal and made to order in New York City’s Diamond District, the Hydrangea Pendant is designed and finished by master jewelers. Choose the pendant alone or complete the necklace with one of Cove’s available chain options, including round box chains and the Omega chain shown in the product imagery.

The bold color combination makes this London Blue Topaz necklace especially beautiful worn on its own, allowing the gemstone and green diamond halo to remain the focus. It also pairs naturally with the Hydrangea Ring for a coordinated fine-jewelry set inspired by New England’s coastal landscape.

Hydrangeas have long been associated with gratitude, love and meaningful connection, making the pendant a thoughtful fine jewelry gift for a mother, partner or someone tied to a special place or memory. More than a seasonal piece, its connection to Cape Cod gives the design a personal sense of place that feels unmistakably Cove.
Why You'll Love It

The deep ocean-blue center stone and sea-glass green diamond halo create an unexpected color pairing that feels distinctly Cove. Meaningful enough to give and striking enough to become a signature piece, it brings the colors of the New England coast beautifully close.

The Cove Fine Jewelry Experience

About Our Gemstones

Each piece is thoughtfully designed and handcrafted in the United States by master jewelers, using solid 14k gold and responsibly sourced materials.

Product pages specify whether gemstones are natural, lab-grown, or enhanced where applicable.

Most Cove gemstone jewelry is designed for everyday wear. Care recommendations may vary depending on the hardness of the gemstone.

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.
