Lab-Grown Diamond Engagement Ring

Light catches the elongated curve of the marquise diamond, casting a slender, graceful shadow that seems to dance with every movement. This semi-set engagement ring invites you to choose a 10 x 5 mm marquise stone, its pointed ends drawing the eye along the finger with a quiet elegance.

Crafted from cool 14K white gold, the mounting features a delicate solitaire setting designed for low profile wear. The slender prongs cradle the stone securely while allowing maximum light to enter, enhancing the diamond’s signature brilliance. The band’s smooth finish and subtle taper ensure comfort for daily wear, slipping easily beneath gloves or alongside stackable rings.

Each piece is carefully shaped and polished in our Williamsburg studio, where precision meets thoughtful design. The lab-grown diamond option offers a clear, sustainable choice without compromising on clarity or fire.

Ideal for those who appreciate refined geometry and understated romance, this ring complements slender to medium finger sizes, emphasizing length and grace. Its minimalist silhouette suits a modern lifestyle, balancing presence with discretion.
