Lab-Grown Diamond Engagement Ring

When sunlight catches the sharp edges of a square diamond, it fractures into a quiet dance of light and shadow—an intimate moment of geometry and glow. This semi-set solitaire ring invites you to select a 3 x 3 mm square lab-grown diamond, whose precise facets reflect a modern clarity with subtle warmth.

Crafted from 14K rose gold, the band’s gentle blush complements the diamond’s crisp lines, while the low-profile setting keeps the silhouette sleek and unobtrusive. Each ring is hand-finished in our Williamsburg studio, polished to a soft sheen that feels smooth against the skin and balances everyday wear with refined elegance.

Our diamonds are sustainably grown, offering a clear conscience alongside their luminous presence. The modest size and solitaire style suit those who appreciate minimalist statements—ideal for stacking or wearing solo, with a comfort fit that slides easily beneath gloves or rings.

Should you wish to adjust the band’s size, resizing is available without compromising the ring’s integrity. Lead times reflect our commitment to meticulous craftsmanship, ensuring your custom design is ready with care.
