Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This three-stone semi-set engagement ring in 18K yellow gold frames a 6 x 3 mm marquise center with two delicate side stones, each carefully positioned to enhance its tapered drama.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a smooth, low-profile setting that sits close to the finger, ideal for daily wear. The artisan finish reveals subtle hammer marks beneath a polished surface, a quiet signature of Brooklyn craftsmanship. The semi-set design allows you to select a lab-grown marquise diamond that meets your clarity and color preferences, ensuring a personalized centerpiece.

Each lab-grown diamond is chosen for its ethical origin, reducing environmental impact without compromising brilliance. The 18K yellow gold band offers a warm glow that complements the marquise’s vintage-inspired silhouette while maintaining modern durability.

This ring suits those who appreciate sculptural elegance and a refined hand feel, with a slender profile that layers beautifully alongside wedding bands or stackable rings. Its narrow width and secure setting also make it glove-friendly for colder seasons.

Should you need resizing, our in-house jewelers provide precise adjustments to maintain the ring’s balance and comfort. Typical lead times for custom stone setting range from four to six weeks.
