Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of an emerald cut diamond, casting a serene, glassy glow that feels both architectural and intimate. This semi-set three-stone mounting in 10K yellow gold awaits your choice of a 12 x 10 mm center stone, designed to showcase the emerald’s signature step-cut clarity and depth.

Handcrafted in our Williamsburg studio, the band’s smooth, low-profile silhouette ensures comfortable daily wear while the three-stone setting balances presence with subtlety. Each curve and angle is carefully finished to a soft polish, reflecting the artisan’s attention to detail and the quiet strength of the metal beneath.

Our commitment to ethical jewelry is reflected in the lab-grown diamond clarity this setting embraces—sustainable brilliance without compromise.

The ring’s shape and size suit those who appreciate architectural elegance and desire a piece that layers well with other bands or stands alone with quiet confidence. Its comfort fit and moderate height make it glove-friendly and ideal for everyday life.

Should you need resizing, our in-studio experts ensure a precise adjustment without disrupting the ring’s balance or finish.
