Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow that dances across the hand. This 10 x 5 mm marquise center stone is cradled in a 14K white gold setting, where delicate accent stones trace the band’s gentle curve, enhancing the diamond’s tapered brilliance without overpowering its refined shape.

Each ring is meticulously crafted in our Williamsburg studio, where the artisan’s touch ensures a low-profile setting that rests comfortably for daily wear. The band’s smooth finish and subtle accents balance visual intrigue with practical elegance, designed to slip easily beneath gloves or stack alongside complementary bands.

Our commitment to sustainability shines through the lab-grown diamond’s clarity and ethical origin, offering a conscious choice without compromise on radiance or craftsmanship.

Ideal for those who appreciate a blend of architectural drama and delicate detail, this ring suits slender to medium finger sizes, elongating the hand with its graceful form. Its comfort fit and secure prong setting invite everyday wear, from quiet mornings to evening celebrations.

Should you need a custom adjustment, resizing is handled expertly in-house to maintain the ring’s integrity and finish.
