Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 6 x 6 mm square diamond, casting a quiet geometry of light across your hand. This five-stone semi-set invites your choice of a lab-grown center, framed by delicate side stones that echo its precise angles.

Crafted in warm 18K yellow gold, the band balances a refined presence with everyday comfort, its smooth finish and low-profile setting designed to slip easily beneath gloves or stack alongside other favorites. Each prong is hand-finished in our Williamsburg studio, ensuring a secure cradle that highlights the diamond’s architectural clarity without excess height.

Our commitment to ethical jewelry shines through the lab-grown diamond’s exceptional clarity and sustainable origin, offering brilliance without compromise.

Ideal for those who appreciate modern geometry with a romantic touch, this setting suits a square cut’s crisp lines while maintaining a gentle wearability for daily life.

Should you need resizing, our in-studio artisans handle adjustments with care to preserve the band’s integrity and comfort fit.
