Lab-Grown Diamond Engagement Ring

When light catches the gentle curves of a 7 x 7 mm heart-shaped diamond, it reveals a quiet promise—intimate and unmistakably personal. This semi-set halo ring invites you to select a center stone that will become the heart of your story.

Crafted in 10K white gold, the band is shaped with a subtle comfort fit, its low-profile halo setting designed to cradle the stone securely while allowing daily wear without catching. Each curve and facet is meticulously finished in our Williamsburg studio, where artisan hands refine every detail to a soft, tactile glow.

Our lab-grown diamonds offer a clarity and brilliance that honors both your values and the environment, reflecting a commitment to ethical jewelry without compromise.

This design suits those who appreciate a romantic silhouette with modern restraint—its halo enhances the heart shape’s natural warmth, while the band’s slender profile pairs effortlessly with stacking rings or a wedding band. The semi-set option lets you choose a diamond that fits your vision and budget.

Resizing is available to ensure a perfect fit, and our team is happy to guide you through care and customization options.
