Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that seems to whisper of quiet promises. This semi-set halo engagement ring in platinum frames a 9 x 4.5 mm marquise stone, inviting you to select a center that balances architectural drama with refined elegance.

Crafted in cool, polished platinum, the halo setting enhances the diamond’s pointed ends while offering a secure, low-profile embrace. The band’s smooth finish and subtle width ensure comfort for daily wear, while the halo’s delicate pavé adds a gentle shimmer without overwhelming the stone’s natural shape. Each piece is meticulously inspected in our Williamsburg studio to meet exacting standards of finish and durability.

Our commitment to lab-grown diamonds means this ring carries a clarity and ethical transparency that aligns with a modern, conscientious lifestyle. The sustainable origin of the center stone reduces environmental impact without compromising on light performance or fire.

Designed for those who appreciate a blend of vintage-inspired romance and contemporary minimalism, this ring suits slender to medium finger sizes and pairs beautifully with stacking bands or a wedding band of similar profile. Its low setting also makes it glove-friendly and practical for everyday moments.
