Lab-Grown Diamond Engagement Ring

Imagine the soft glow of a 12 x 12 mm cushion diamond poised to catch the light with every movement—its rounded corners and gentle facets offering a vintage-inspired warmth. This semi-set halo mounting in 10K white gold frames the center stone with a delicate circle of smaller diamonds, enhancing brilliance while maintaining a low-profile silhouette that slips comfortably beneath a sleeve.

Crafted in Williamsburg, this setting balances refined detail with everyday practicality: the band’s smooth finish and subtle curvature ensure a comfort fit, while the halo’s secure prong setting protects the stone without adding bulk. Each piece is meticulously inspected to meet exacting standards, reflecting the studio’s commitment to precision and durability.

Ethically sourced lab-grown diamonds provide a clear, sustainable alternative, embodying a modern approach to fine jewelry without compromise.

Designed for those who appreciate a blend of classic charm and contemporary wearability, this ring suits hands that favor a statement centerpiece with a graceful profile—ideal for stacking or solo wear. Its low height and secure setting make it glove-friendly and resilient for daily life.

Should you wish to adjust the fit, resizing is available with care to preserve the integrity of the setting and metalwork.
