Lab-Grown Diamond Engagement Ring

Imagine the quiet thrill of a heart-shaped diamond poised to capture a lifetime of promises. This semi-set engagement ring foundation in warm 18K yellow gold awaits your choice of a 10 x 10 mm heart-cut center stone, its gentle curves echoing the intimate shape of affection.

Handcrafted in our Williamsburg studio, the three-stone setting balances artisan precision with everyday wearability. The low-profile prongs cradle side stones securely, while the smooth band offers a comfort fit that feels natural on the hand. Each curve and angle is refined to catch light subtly, enhancing the heart’s romantic silhouette without overwhelming daily ease.

Our commitment to sustainability is reflected in the option for a lab-grown diamond, offering clarity and brilliance with a lighter environmental footprint.

Designed for those who appreciate meaningful symbolism paired with practical elegance, this ring suits a range of finger shapes and sizes. Its modest height makes it glove-friendly and ideal for stacking alongside wedding bands or personal heirlooms.

Should you need resizing, our Brooklyn studio provides expert adjustments to ensure a seamless fit without compromising the ring’s integrity.
