Lab-Grown Diamond Engagement Ring

Imagine the moment light catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye with quiet drama. This semi-set three-stone engagement ring foundation in platinum offers a sleek, modern-minimal frame designed to highlight a 12 x 6 mm center stone of your choosing.

Crafted in Williamsburg, the platinum band is polished to a soft sheen, balancing durability with a refined low-profile setting that sits comfortably for daily wear. The three-stone layout provides architectural clarity, allowing side stones to enhance the center’s distinctive shape without overwhelming it.

Each lab-grown diamond is selected for exceptional clarity and brilliance, reflecting an ethical commitment to sustainability without compromising on sparkle. The platinum’s cool tone complements the marquise’s glassy facets, creating a confident yet understated statement.

Ideal for those who appreciate structured elegance and a ring that layers well with other bands, this mounting suits slender to medium finger sizes and fits easily under gloves or sleeves thanks to its streamlined silhouette.

Resizing is available to ensure a precise fit, and the semi-set design invites you to select a center stone that resonates personally, making this ring uniquely yours.
