Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate sparkle that seems to dance with every movement. This three-stone semi-set engagement ring in 14K yellow gold frames a 7 x 3.5 mm marquise center, its pointed ends drawing the eye along the finger with graceful intent.

Crafted in Williamsburg, the band’s gentle curve and polished finish offer a smooth, comfortable fit for daily wear. The three-stone setting balances presence with subtlety, allowing the marquise’s signature tapered drama to shine without overwhelming. Each prong is meticulously shaped and hand-set to secure the stone while maintaining a low profile that slips easily beneath gloves or alongside stackable bands.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both the environment and your values. This ring’s ethical foundation complements its refined design, marrying beauty with responsibility.

Ideal for those who appreciate a blend of classic romance and modern craftsmanship, this piece suits slender to medium fingers, elongating the hand with its architectural shape. The semi-set allows you to select a center diamond that perfectly matches your vision and budget.
