Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of the emerald-cut diamond, casting a serene glassy glow that draws the eye along its architectural lines. This semi-set engagement ring offers a refined foundation crafted from warm 18K yellow gold, designed to cradle a 7.5 by 5.5 mm emerald-shaped stone with precision and care.

Hand-forged in our Williamsburg studio, the band’s smooth finish and subtle taper ensure a comfortable fit that sits low against the finger, ideal for daily wear. The mounting’s clean silhouette highlights the diamond’s clarity and step-cut geometry without distraction, while the sturdy prongs secure the stone with artisan attention to detail.

Each lab-grown diamond chosen for this setting reflects our commitment to ethical jewelry, offering brilliance and purity with a significantly reduced environmental footprint. The ring’s modest profile and balanced proportions make it well suited for those who appreciate architectural elegance paired with understated comfort.

Because this is a semi-set, the center stone is selected separately, allowing you to personalize the diamond’s exact cut and clarity. Resizing is available to ensure the ring fits seamlessly into your everyday life.
