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 frames a 6 x 3.5 mm marquise center with two delicate side stones, each carefully positioned to enhance its tapered drama.

Crafted from warm 18K yellow gold, the band is shaped and polished in our Williamsburg studio to a smooth comfort fit, designed for daily wear without catching or discomfort. The low-profile setting keeps the stones close to the finger, making it glove-friendly and ideal for stacking with other bands.

Each ring begins as a hand-finished foundation, ready to be paired with a lab-grown diamond of your choice—offering clarity and brilliance with a lighter environmental footprint. Our artisans inspect every detail, ensuring the prongs secure the marquise’s pointed ends without overshadowing its architectural elegance.

Its slender silhouette suits hands that appreciate refined geometry and a subtle statement, balancing vintage allure with modern craftsmanship. The semi-set option invites personal selection, allowing you to tailor the center stone to your vision.

Resizing is available to ensure a precise fit, with care instructions provided to maintain the gold’s warm glow and the diamond’s sparkle over time.
