Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a 12 x 6 mm marquise diamond, it creates a striking interplay of brilliance and shadow that draws the eye along the finger’s natural line. This solitaire semi-set ring offers a refined foundation, crafted in warm 18K rose gold with a sleek white gold band, designed to balance subtle contrast with enduring elegance.

The setting is engineered for daily wear: a low-profile bezel that secures the stone close to the hand, minimizing snagging while maintaining a confident presence. The band’s gentle comfort fit ensures it sits smoothly beneath the finger, ideal for stacking or solo wear without bulk.

Each piece is meticulously finished in our Williamsburg studio, where precision meets quiet craftsmanship. The lab-grown marquise diamond reflects our commitment to ethical sourcing and sustainability, offering clarity and fire without compromise.

Its elongated shape flatters a variety of hand sizes, especially those seeking a ring that visually lengthens the finger. The semi-set design invites you to select a center stone that resonates personally, making this ring a true expression of individuality.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers attentive care with thoughtful turnaround times.
