Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an 8 x 6 mm oval diamond, casting a gentle glow that seems to stretch across the hand. This semi-set platinum solitaire ring offers a refined stage for your chosen stone, framed by six slender prongs that balance security with an open, airy presence.

Crafted in platinum for enduring strength and a cool, luminous finish, the mounting is designed with a low-profile silhouette that rests comfortably against the skin. Each prong is meticulously shaped and polished in our Williamsburg studio, ensuring a seamless blend of modern minimalism and structural clarity.

Choosing a lab-grown diamond here means embracing a sustainable approach without compromise on brilliance or purity. The oval cut’s graceful elongation flatters a variety of finger shapes, while the solitaire style keeps the focus singular and confident.

Its lightweight feel and streamlined design make it ideal for everyday wear, whether worn solo or paired with a wedding band. The semi-set format invites you to select a center stone that reflects your personal story, with resizing and finishing handled expertly in-house.
