Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond catching light as it elongates the finger, its pointed ends drawing the eye with graceful precision. This semi-set platinum mounting awaits your choice of a 9 x 4.5 mm marquise center, designed to showcase the stone’s tapered drama within a refined artisan setting.

Crafted in our Williamsburg studio, the band’s smooth platinum surface is hand-finished to a soft sheen, balancing durability with a comfortable fit for daily wear. The low-profile design keeps the ring close to the hand, making it glove-friendly and ideal for stacking alongside complementary bands.

Each piece reflects our commitment to ethical jewelry: lab-grown diamonds offer clarity and brilliance without the environmental cost of mining. This mounting is a foundation for a conscious choice, marrying tradition with modern responsibility.

Its slender silhouette suits those who appreciate architectural elegance and a ring that feels as natural as it looks striking. The semi-set format invites you to select a marquise diamond that matches your vision, whether you prefer a bright white or a warmer hue.
