Lab-Grown Diamond Engagement Ring

Under the soft glow of a Brooklyn evening, the promise of a square solitaire begins to take shape—its precise edges catching light like whispered vows. This semi-set ring invites your choice of a 2.5 x 2.5 mm square lab-grown diamond, a shape that balances architectural clarity with intimate sparkle.

Crafted in 18K white gold, the mounting offers a refined silhouette with a low-profile setting that rests comfortably against the finger. The band’s smooth finish and subtle taper ensure it wears effortlessly alone or alongside a wedding band, designed for daily life in Williamsburg’s rhythm.

Each piece reflects a commitment to ethical jewelry, featuring a lab-grown diamond that embodies clarity and sustainability without compromise. The semi-set design allows for personal selection, ensuring your center stone aligns perfectly with your vision.

Ideal for those who appreciate modern geometry and understated elegance, this solitaire suits slender to medium finger sizes and pairs well with stackable bands. Its modest scale and comfort fit make it glove-friendly and unobtrusive.

Should you need resizing or guidance on stone selection, our Brooklyn studio offers expert consultation with attentive care and a typical lead time of 4–6 weeks.
