Lab-Grown Diamond Engagement Ring

Under the soft glow of a Brooklyn evening, the sharp geometry of an 8 x 8 mm Asscher cut diamond catches the light with architectural precision, its step-cut facets drawing the eye inward like a secret whispered in shadow. This platinum halo engagement ring frames the center stone with a delicate circle of smaller diamonds, enhancing its vintage-inspired clarity without overwhelming the clean lines.

Crafted in Williamsburg, the ring’s low-profile setting balances presence with everyday wearability, the comfort-fit band smoothing against the skin for seamless daily grace. Each facet is meticulously polished and inspected in-studio, ensuring the platinum’s cool sheen complements the diamond’s glassy depth.

Our lab-grown diamonds offer a clarity and brilliance equal to mined stones, with a fraction of the environmental impact—an ethical choice woven quietly into the ring’s story.

Designed for those who appreciate refined geometry and subtle drama, this halo setting suits hands that favor architectural elegance, while the platinum band’s smooth contour invites stacking or solo wear. Its modest height slips easily beneath gloves or sleeves, making it a companion for both intimate moments and city rhythms.

Should you need a custom fit, resizing is handled expertly in our Brooklyn studio, ensuring your ring feels as natural as the moment it marks.
