Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic shadow across the hand. This three-stone semi-set ring in 14K yellow gold frames a 9 x 4.5 mm marquise center, its shape evoking vintage allure with a modern edge.

Each band is hand-forged in our Williamsburg studio, the warm gold polished to a satin finish that feels smooth against the skin. The three-stone setting balances presence with wearability, designed low-profile to slip comfortably beneath gloves or stack alongside daily rings.

Our diamonds are lab-grown, offering clarity and brilliance with a smaller environmental footprint. This ethical choice aligns with a commitment to sustainability without compromising on radiance.

The ring suits those who appreciate refined geometry and a statement that elongates the finger elegantly. Its comfort fit and modest height make it ideal for everyday wear, whether alone or paired with a wedding band.

Resizing is available to ensure a precise fit, crafted carefully to maintain the integrity of the setting.
