East West Marquise Gemstone Necklace

Description

Marquise Lab-Grown Emerald Necklace in 14k Gold

Our Marquise Lab-Grown Emerald Necklace captures the vibrance of the sea and the precision of fine craftsmanship. Each pendant features a vivid lab-grown marquise-cut emerald, hand-selected for its brilliant green hue and clarity, and meticulously set by hand in your choice of solid 14k gold.

Suspended from a refined 16-inch gold chain, the marquise gemstone evokes the natural curve of a cresting wave — a symbol of balance, renewal, and effortless elegance. Each necklace is designed and finished by master jewelers in New York’s Diamond District, ensuring exceptional craftsmanship and traceable materials from start to finish.

Every detail — from the secure bezel setting to the elongated silhouette — reflects Cove Fine Jewelry’s commitment to American-made quality and coastal-inspired design with a true sense of place.

For a personalized touch, chain length can be customized upon request. Pair it with our Marquise Diamond Necklace for a complementary, signature look that transitions seamlessly from shore to city.

The Cove Fine Jewelry Experience

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.

Cove's Quality Guarantee

Cove Fine Jewelry Quality Guarantee —

All lab-grown materials are clearly disclosed in each product description.
