Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of a marquise diamond, casting a slender, dramatic silhouette that feels both bold and intimate. This semi-set platinum band awaits a 10 x 5 mm marquise center, its sleek profile designed to cradle the stone securely while maintaining a refined, low-profile presence.

Handcrafted in our Williamsburg studio, the platinum band is meticulously shaped for comfort fit, its smooth interior contouring gently to the finger. The solitaire setting’s prongs are precisely aligned to showcase the marquise’s tapered points, ensuring durability without sacrificing elegance. Each piece undergoes rigorous finishing and inspection to meet exacting standards.

Our diamonds are lab-grown, offering a clarity and brilliance equal to mined stones but with a significantly reduced environmental footprint.

Ideal for those who appreciate a striking yet wearable ring, this mounting suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding band. Its modest height allows for glove-friendly wear and everyday ease.

Resizing is available to ensure a perfect fit, and lead times reflect the careful handcrafting process unique to our Brooklyn atelier.
