Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that seems to stretch beyond the finger. This semi-set halo engagement ring foundation in polished platinum offers a refined stage for a 10 x 5 mm marquise center, designed to amplify the stone’s tapered drama and vintage allure.

Crafted with precision in our Williamsburg studio, the platinum band is shaped for comfort and daily wear, its low-profile setting ensuring the halo frames the center stone without overwhelming. Each curve is hand-finished to a smooth, tactile grace that invites touch, while the secure prong arrangement promises lasting stability.

Our commitment to ethical jewelry shines through the use of lab-grown diamonds, chosen for their clarity and sustainable origins, reflecting a modern approach to romance and responsibility.

This ring suits those who appreciate a balance of bold geometry and subtle elegance—its slender silhouette elongates the hand and layers beautifully with other bands. The semi-set design allows you to select a marquise diamond that resonates personally, making the final piece uniquely yours.
