Lab-Grown Diamond Engagement Ring

Sunlight catches the softly rounded corners of a 12 x 12 mm cushion diamond, its gentle glow inviting quiet admiration. This semi-set solitaire ring offers a foundation sculpted from 18K white gold, meticulously hand-finished in our Williamsburg studio to a smooth, low-profile silhouette that rests comfortably against the finger.

The band’s subtle weight balances the generous center stone, designed to showcase the cushion’s vintage-inspired warmth without overwhelming daily wear. Each curve is polished to a satin sheen, ensuring the setting complements rather than competes with the diamond’s soft sparkle.

Crafted with lab-grown clarity, this ring reflects a commitment to sustainability and ethical sourcing, marrying modern technology with artisanal skill. Its modest height and streamlined profile make it an ideal choice for those seeking a solitaire that layers effortlessly with wedding bands or stackable rings.

Because this is a semi-set, the center stone is selected separately, allowing you to tailor the diamond’s exact cut and clarity to your preference. Resizing is available to ensure a precise fit, with care instructions provided to maintain the metal’s subtle sheen over time.
