Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of a 12mm round diamond, poised to become the heart of a three-stone engagement ring. This semi-set foundation in warm 14K yellow gold offers a handcrafted canvas, meticulously shaped and polished in our Williamsburg studio to cradle your chosen center stone with precision.

The band’s subtle taper and smooth finish ensure a comfortable fit, designed for everyday wear without sacrificing elegance. Its low-profile setting balances presence with practicality, allowing the diamond’s classic brilliance to command attention while remaining glove-friendly.

Each piece reflects our commitment to ethical jewelry: lab-grown diamonds with clarity and sparkle equal to mined stones, crafted sustainably in Brooklyn’s artisan workshops. This ring suits those who appreciate a blend of tradition and modern responsibility, perfect for stacking or wearing solo as a statement of refined taste.
