Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the hand’s natural lines. This semi-set three-stone ring foundation in 14K yellow gold offers a warm, tactile contrast to the stone you select, inviting a personal touch to the centerpiece.

Each band is meticulously crafted in our Williamsburg studio, shaped for a comfortable fit that sits low against the finger without sacrificing presence. The polished finish highlights the gentle curve of the shank, designed to complement the marquise’s distinctive geometry while allowing side stones to frame the center with balanced elegance.

Our commitment to sustainability is reflected in the choice of lab-grown diamonds, ensuring clarity and brilliance with a lighter environmental footprint. This ring’s structure supports daily wear, its modest profile making it glove-friendly and ideal for stacking with complementary bands.

Perfect for those who appreciate refined craftsmanship and a ring that adapts seamlessly to an active lifestyle, the semi-set design invites you to select a marquise diamond that resonates with your vision. Resizing is available to ensure a precise fit, crafted with the same care as the original design.
