Lab-Grown Diamond Engagement Ring

Sunlight catches the delicate dance of three stones, the center poised to become your chosen round diamond, its 12 mm diameter promising a luminous focal point. This semi-set engagement ring offers a handcrafted 14K white gold band, shaped and polished in our Williamsburg studio to a refined comfort fit that feels like a second skin.

The three-stone setting balances presence with wearability—each prong meticulously forged to secure your center stone while allowing maximum light to enhance its brilliance. The band’s subtle taper and smooth finish invite daily wear, whether layered with other stackable pieces or worn alone.

Crafted with lab-grown diamonds, this ring embodies a commitment to ethical jewelry, reducing environmental impact without compromising clarity or fire. The round shape’s classic sparkle complements a variety of hand sizes, elongating fingers with its balanced symmetry.

Resizing is available to ensure a precise fit, and our studio process includes careful inspection at every stage to meet exacting standards. Whether you visit us in Williamsburg or design online, this semi-set invites you to select a center stone that reflects your unique story.
