Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate sparkle that dances with every movement. This three-stone semi-set engagement ring in 14K yellow gold frames a 10 x 5 mm marquise center, its tapered points lending a graceful drama to the hand.

Crafted with precision in Williamsburg, the band’s warm gold hue complements the diamond’s glassy brilliance, while the low-profile setting ensures daily wearability without catching. Each prong is hand-finished for secure hold and subtle elegance, balancing the ring’s romantic form with modern comfort.

Our lab-grown diamonds offer the clarity and fire of natural stones with a lighter environmental footprint, reflecting a commitment to ethical jewelry without compromise.

The slender band suits those who appreciate refined geometry and a ring that layers effortlessly with wedding bands or stackable accents. Its shape elongates the finger, ideal for hands seeking a blend of boldness and grace.

Should you wish to adjust sizing, our Brooklyn studio provides expert resizing to maintain the ring’s integrity and comfort.
