Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that seems to stretch beyond the finger. This semi-set platinum solitaire ring offers a refined foundation for an 8 x 4 mm marquise center stone, its pointed ends lending a graceful tension to the design.

Crafted in platinum, the band is polished to a soft sheen that complements the diamond’s sharp geometry without overpowering it. The mounting’s low-profile setting ensures the ring sits close to the hand, balancing presence with everyday comfort. Each piece is meticulously finished in our Williamsburg studio, where artisan hands inspect every curve and prong for durability and refined detail.

Choosing a lab-grown diamond for this setting reflects a commitment to ethical jewelry, reducing environmental impact while maintaining exceptional clarity and brilliance.

Ideal for those who appreciate architectural elegance and a sleek silhouette, this ring’s slender band feels light and unobtrusive, making it easy to stack or wear solo. Its shape naturally elongates the finger, lending a subtle sophistication to daily wear.
