Lab-Grown Diamond Engagement Ring

Under the soft glow of Williamsburg’s evening light, a square lab-grown diamond captures the quiet geometry of a modern romance. This 5 x 5 mm gem, framed by a delicate halo of smaller stones, reflects light with a precise brilliance that feels both architectural and intimate.

Set in cool platinum, the ring’s low-profile halo setting balances sparkle with everyday wearability. The band’s smooth finish and comfort fit ensure it rests lightly against the skin, inviting daily moments without interruption. Each facet is polished and inspected in our Brooklyn studio, where craftsmanship meets thoughtful design.

Crafted from ethically sourced lab-grown diamonds, this piece carries a clarity and sustainability that honors both the earth and your values.

Its square shape lends a confident edge, ideal for those who appreciate clean lines and a subtle statement. The halo enhances the center stone’s presence without overwhelming, making it a graceful companion for stacking or solo wear.

Should you need resizing, our in-studio team offers precise adjustments to ensure a seamless fit. Typical lead times reflect our commitment to careful handcrafting rather than rush production.
