Lab-Grown Diamond Engagement Ring

Imagine the subtle elongation of a hand caught in soft afternoon light, where a marquise-shaped diamond draws the eye with its tapered drama and graceful silhouette. This semi-set halo ring in platinum offers a refined foundation, ready to cradle a 9 x 4.5 mm lab-grown marquise diamond, its pointed ends framed by a delicate halo that enhances brilliance without excess height.

Crafted for everyday wear, the low-profile setting keeps the band close to the finger, reducing snagging while maintaining a confident presence. The platinum band is polished to a satin finish, balancing durability with a smooth comfort fit that feels natural through daily rhythms. Each mounting undergoes meticulous inspection in our Williamsburg studio to ensure precision and lasting strength.

Choosing a lab-grown diamond here reflects a commitment to ethical jewelry—minimizing environmental impact while celebrating clarity and light. The marquise shape’s elongated form flatters slender fingers and pairs seamlessly with stacking bands or a wedding band designed to nestle alongside.

Should you need resizing, our in-studio process accommodates adjustments with care, preserving the integrity of the setting. Lead times for completion vary slightly depending on stone selection, but we guide you through each step with transparency.
