Lab-Grown Diamond Engagement Ring
When light catches the gentle curves of a 6 x 6 mm heart-shaped diamond, it reveals a quiet promise, a tender geometry that speaks directly to the wearer’s story. This semi-set platinum engagement ring offers a refined foundation, designed to showcase your chosen center stone with a low-profile setting that rests close to the finger, minimizing snagging and maximizing comfort.
Crafted in Williamsburg, the band’s polished platinum surface is carefully finished to a smooth, comfort fit that suits daily wear without sacrificing elegance. The subtle accent details frame the heart shape without overwhelming it, allowing the diamond’s unique silhouette to remain the focal point.
Each lab-grown diamond selected for this setting reflects a commitment to ethical sourcing and sustainability, offering clarity and brilliance without compromise.
Ideal for those who appreciate a delicate yet durable ring, this mounting complements slender to medium finger sizes and pairs effortlessly with stacking bands or wedding rings. Its low profile ensures it slides easily under gloves or sleeves, making it a practical choice for everyday life.
Should you need resizing, our Brooklyn studio provides precise adjustments to ensure a perfect fit, with typical lead times tailored to your schedule.
