Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of an oval diamond, casting a gentle glow that seems to stretch beyond the stone itself. This halo setting frames a 6 x 4 mm lab-grown oval diamond with a precise platinum band, its cool sheen balancing modern minimalism with architectural clarity.

Crafted in Williamsburg, Brooklyn, the ring’s low-profile halo setting ensures daily wearability without sacrificing brilliance. The platinum band is polished to a smooth comfort fit, designed to sit lightly yet securely on the finger. Each facet of the diamond is carefully inspected to maximize light return, while the halo’s delicate pavé adds subtle sparkle without overwhelming the center stone.

Lab-grown for clarity and sustainability, this ring reflects a commitment to ethical jewelry that honors both beauty and conscience.

Its slender silhouette suits those who appreciate refined structure and confident understatement, pairing effortlessly with stackable bands or worn solo. The oval shape elongates the hand, offering a graceful presence that feels both contemporary and timeless.

Should you need resizing, our Brooklyn studio provides expert adjustments to ensure a perfect fit without compromising the ring’s integrity.
