Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light with a graceful, tapered brilliance. This three-stone semi-set ring in 10K white gold frames a 9 x 4.5 mm center stone, designed to balance architectural elegance with everyday wearability.

Each band is meticulously crafted in our Williamsburg studio, where the cool sheen of white gold is hand-finished to a smooth comfort fit. The low-profile setting ensures the ring sits close to the finger, making it ideal for stacking or pairing with a wedding band without catching on gloves or sleeves.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, offering clarity and sparkle with a smaller environmental footprint. This ring’s semi-set design invites you to select a center stone that reflects your personal story, while the side stones enhance its refined geometry.

Its slender proportions suit hands that appreciate both statement and subtlety, elongating the finger with a modern yet timeless silhouette. Resizing is available to ensure a perfect fit, crafted with care to maintain the ring’s balance and comfort.
