Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, tracing a subtle silhouette that stretches gracefully across the finger. This three-stone semi-set engagement ring in 18K rose gold offers a refined balance of presence and comfort, designed for everyday wear without excess height.

Crafted in Williamsburg, the band’s low-profile setting cradles a 7 x 3.5 mm marquise center stone, flanked by two smaller side stones that enhance its architectural elegance. The smooth, gently tapered shank ensures a secure fit with a comfort contour that feels natural against the skin. Each piece is meticulously finished and inspected in-studio to meet exacting standards.

Choosing a lab-grown diamond means embracing clarity and brilliance with a lighter environmental footprint, reflecting a modern approach to ethical jewelry.

This ring suits those who appreciate a sleek silhouette that complements slender or average finger shapes, and its low profile makes it glove-friendly and stackable with other bands. The three-stone design adds dimension without bulk, ideal for daily life in Brooklyn’s vibrant rhythm.

Should you need resizing, our studio offers precise adjustments to maintain the ring’s integrity and comfort.
