Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise center, casting a slender, dramatic sparkle that dances with every movement. This three-stone engagement ring is crafted in warm 14K rose gold, its gently curved band hand-finished to a soft, tactile glow that feels like a second skin.

The center marquise diamond, measuring 6 by 3 millimeters, is securely set with delicate prongs that emphasize its tapered silhouette while maintaining a low profile for everyday wear. Flanking stones enhance the ring’s architectural grace without overpowering the refined balance of light and shadow.

Each piece is meticulously inspected in our Williamsburg studio, where artisan techniques meet modern precision, ensuring a seamless comfort fit that slips on easily and wears gracefully through daily life.

Our commitment to sustainability is reflected in the use of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

Designed for those who appreciate subtle drama and elegant craftsmanship, this ring suits slender fingers and pairs beautifully with stackable bands or a simple wedding band. Its low-profile setting makes it glove-friendly and ideal for active lifestyles.

Should you need resizing, our in-house jewelers provide careful adjustments without compromising the ring’s integrity.
