Lab-Grown Diamond Engagement Ring

Imagine the quiet thrill of a heart-shaped diamond catching morning light, its soft curves framed by a delicate halo that amplifies every flicker. This semi-set engagement ring foundation invites you to select a 10 x 10 mm heart diamond, a shape that blends romantic symbolism with a sculptural presence.

Crafted from warm 18K yellow gold, the band is shaped and polished in our Williamsburg studio, where each curve is refined for a smooth, comfortable fit. The halo setting is designed to sit low against the finger, balancing visibility with everyday wearability, while the artisan finish reveals subtle handwork details that catch the eye up close.

Our commitment to lab-grown diamonds ensures clarity and brilliance without compromise, reflecting a sustainable approach to fine jewelry.

This ring suits those who appreciate a bold yet intimate statement—its low profile and rounded edges make it glove-friendly and ideal for stacking with complementary bands. The generous heart shape offers a striking centerpiece for hands of all sizes.

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