Lab-Grown Diamond Engagement Ring
When light catches the elongated silhouette of a marquise diamond, it carves a slender beam that seems to dance along the finger. This semi-set engagement ring offers a 9 x 4.5 mm marquise center, its pointed ends lending a refined drama balanced by delicate accent stones that frame its shape with subtle brilliance.
Crafted from 14K white gold, the band is shaped and polished in our Williamsburg studio to a smooth, comfortable fit that sits low against the hand, ideal for everyday wear. The artisan finish reveals fine details in the prong setting, designed to secure the stone while allowing maximum light to pass through its facets.
Each lab-grown diamond is selected for clarity and ethical provenance, reflecting a commitment to sustainability without compromising on radiance or craftsmanship.
The slender profile and modest height make this ring well-suited for those who appreciate a graceful silhouette that layers effortlessly with other bands or stands alone with quiet confidence.
Should you wish to adjust sizing, our in-studio experts ensure a precise fit with minimal turnaround, preserving the integrity of the setting.
