Hydrangea Emerald and Diamond Trapezoid Ring

Product Description

Lab-Grown Emerald Three-Stone Ring in 14k Gold

The Cove Three-Stone Emerald Ring features a vivid emerald-cut lab-grown emerald set between two step-cut trapezoid diamonds in solid 14k gold. This classic three-stone design highlights the rich green color of the emerald while creating a refined, architectural silhouette inspired by timeless fine jewelry.

At the center of the ring is a striking 11 x 9 mm emerald-cut lab-grown emerald, prized for its clean lines and deep green color. Lab-grown emeralds offer the same physical, chemical, and optical properties as natural emeralds while providing exceptional clarity and vibrant color.

Flanking the center stone are two step-cut trapezoid diamonds totaling approximately .47 carats, graded E color and VVS2 clarity. The trapezoid side stones measure 5 x 3 x 4 mm, creating a balanced three-stone setting that enhances the geometric elegance of the emerald cut.

Three-stone rings traditionally symbolize past, present, and future, making this design an ideal choice for a meaningful fine jewelry piece or a distinctive emerald engagement ring.

Crafted in solid 14k gold and made in the USA, each ring is produced with gold cast in New York City and finished by skilled American artisans. The result is a timeless piece of fine jewelry designed for lasting wear and exceptional craftsmanship.

With its vibrant green gemstone and classic diamond accents, the Cove Lab-Grown Emerald Three-Stone Ring is a bold yet timeless emerald ring designed to stand out.

INSPIRED BY THE COLORS OF THE COAST

Every Gemstone Tells a Story.

Nature has always been our greatest source of inspiration.

The colors found throughout New England's shoreline—from soft sea glass and hydrangea blooms to sandy beaches, ocean waters, and coastal sunsets—come to life through carefully selected gemstones that celebrate both beauty and place.

Each Cove collection is thoughtfully designed to capture a feeling, a memory, and a connection to the coast that can be worn every day.

Discover the Beauty Behind Your Gemstone

Morganite |With its soft blush tones reminiscent of a Cape Cod sunset, Morganite symbolizes compassion, love, and new beginnings. Its gentle color pairs beautifully with solid gold, creating an elegant piece designed for everyday wear.

Aquamarine | Inspired by the crystal-clear waters of the Atlantic Ocean, Aquamarine reflects tranquility, clarity, and adventure. Its timeless blue hue has long been associated with sailors and the sea.

Sapphire | Classic and enduring, Sapphire evokes the deep blues of the New England coastline while symbolizing wisdom, loyalty, and strength.

Peridot | Fresh green hues inspired by summer grasses and coastal landscapes make Peridot a vibrant reminder of growth, renewal, and optimism.

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.
