Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, casting a slender beam that seems to stretch beyond the hand. This semi-set platinum mounting awaits your choice of a 5 x 3 mm marquise center, designed to cradle the stone with delicate prongs that elevate its graceful profile.

Crafted in Williamsburg, the band’s polished platinum offers a cool, substantial feel, its low-profile setting ensuring everyday comfort without sacrificing presence. The solitaire design emphasizes the diamond’s tapered drama, allowing light to dance freely across its facets while the secure setting keeps it poised for daily wear.

Each piece reflects a commitment to ethical jewelry, featuring lab-grown diamonds that combine clarity with sustainability. The refined silhouette suits those who appreciate a ring that feels intimate yet striking, ideal for slender fingers or as a stand-alone statement.

Resizing is available to ensure a perfect fit, and the semi-set nature invites you to select a stone that resonates personally. Whether layered with other bands or worn solo, this mounting balances elegance with practical wearability.
