Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along a graceful arc. This semi-set three-stone engagement ring in 14K yellow gold offers a foundation ready to showcase a 6 x 3.5 mm center stone, framed by two smaller gems that balance drama with refinement.

Handcrafted in our Williamsburg studio, the band’s warm gold surface is carefully polished to a soft glow, while the setting is designed for everyday wear—low profile enough to slip comfortably beneath gloves or stack alongside other bands. The artisan’s touch ensures each prong is precisely shaped to cradle your chosen diamond securely, with subtle shoulders that enhance light reflection without bulk.

Choosing a lab-grown diamond here aligns with a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity.

This ring suits those who appreciate architectural elegance paired with a wearable silhouette—ideal for slender fingers or anyone drawn to the marquise’s distinctive, elongating form. The three-stone layout adds symbolic depth, perfect for marking a shared journey.

Should you need resizing, our in-studio experts handle adjustments with care to maintain the ring’s balance and finish.
