Inspired by the depth and brilliance of the Atlantic, the Atlantic Blue Diamond Pendant captures the spirit of coastal luxury.

At its center, a vivid 1.50 ct (photoed piece 1.59 cttw) emerald-cut lab-grown blue diamond shimmers with oceanic intensity. Certified by IGI and graded VS2 clarity, this stone offers both remarkable beauty and uncompromising quality.

Set in Cove Fine Jewelry’s original 14k gold design, the pendant features a refined emerald-cut frame and a large bail, making it easy to style across multiple chains. Wear it layered or solo—its versatility makes it a timeless staple.

This piece is available with or without a chain, and custom orders can be created in other lab-grown diamond colors, including pink, yellow, and classic white. Each pendant is meticulously crafted in New York’s Diamond District, reflecting Cove’s values of craftsmanship, authenticity, and coastal-inspired design.

Also available with a (white) Emerald Cut Diamond (not photographed).  

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.
