Lab-Grown Diamond Engagement Ring

Sunlight catches the emerald-cut diamond’s broad facets, casting a glassy, architectural shimmer that draws the eye along its elongated silhouette. This semi-set platinum band awaits your choice of a 6.5 x 5 mm center stone, offering a refined foundation shaped by hand in our Williamsburg studio.

Crafted from cool, polished platinum, the mounting features a low-profile bezel setting designed for everyday wear—secure yet unobtrusive, with a comfort fit that rests gently against the finger. Each curve and angle is meticulously finished to a smooth, tactile sheen, reflecting the artisan’s attention to detail.

Choosing a lab-grown diamond here means embracing clarity and sustainability without compromise, a quiet nod to ethical jewelry values woven into every piece.

The slender band suits those who favor minimalist elegance or layering with stackable rings, while the emerald shape’s linear grace complements longer fingers and modern sensibilities alike.

Should you need resizing, our in-studio experts ensure a precise, comfortable adjustment without disrupting the ring’s balance.
