Lab-Grown Diamond Engagement Ring

Imagine the quiet gleam of a square diamond poised to catch the light, framed by a delicate halo that multiplies its sparkle. This semi-set engagement ring foundation invites your choice of a 5 x 5 mm square center, offering a modern geometry that balances boldness with refined clarity.

Crafted from 18K palladium white gold, the band is meticulously hand-finished in our Williamsburg studio, its cool, silvery surface polished to a soft, tactile glow. The halo setting is designed to sit low on the finger, ensuring everyday comfort while enhancing the diamond’s brilliance through precise artisan prong work.

Each piece reflects our commitment to ethical jewelry: the setting awaits your lab-grown diamond, a choice that honors sustainability without compromising on clarity or fire.

Its streamlined profile suits those who appreciate subtle sophistication—ideal for stacking alongside a wedding band or worn solo for a clean, architectural statement. The comfort fit band feels natural through daily wear, and the low-profile setting slips easily beneath gloves or sleeves.

Should you need resizing, our in-house artisans handle adjustments with care, preserving the ring’s integrity and finish.
