Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated facets of a marquise diamond, it casts a slender, dramatic sparkle that seems to dance along the finger. This semi-set halo engagement ring foundation in platinum offers a refined stage for a 12 x 6 mm marquise stone, designed to amplify its tapered elegance with a delicate halo that enhances brilliance without overwhelming.

Crafted in our Williamsburg studio, the platinum band is hand-finished to a smooth, comfort fit that sits low against the hand, making it ideal for daily wear. The halo setting is engineered to cradle the center stone securely while allowing light to flood from every angle, a testament to meticulous artisan technique and quality control.

Each lab-grown diamond chosen for this setting reflects a commitment to ethical sourcing and environmental mindfulness, offering clarity and fire without compromise.

The slender profile and elongated shape suit hands seeking a graceful, elongating effect, while the halo adds a subtle vintage-inspired glow. Its low profile ensures compatibility with gloves and stacking bands, balancing statement with practicality.

Should you need adjustments, resizing is handled with care in-studio to maintain the integrity of the platinum and setting.
