Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond catching light with every turn of the hand, its elongated silhouette lending a graceful sweep to the finger. This semi-set three-stone engagement ring foundation in platinum offers a refined stage for a 7 x 3.5 mm marquise center, framed by two complementary side stones to enhance its architectural elegance.

Crafted in our Williamsburg studio, the platinum band is meticulously hand-finished to a smooth comfort fit, designed for daily wear without bulk. The low-profile setting balances presence with practicality, ensuring the ring slips easily beneath gloves or stacks effortlessly with other bands.

Each lab-grown diamond is selected for clarity and brilliance, reflecting our commitment to sustainable, ethical jewelry without compromise on sparkle or character.

This ring suits those drawn to distinctive shapes and a three-stone narrative—ideal for hands that appreciate a sleek, elongated form and a setting that honors both tradition and modernity.

Should you wish to adjust proportions or explore custom side stones, resizing and bespoke options are available with thoughtful consultation.
