Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points tracing a delicate arc that seems to stretch the fingers gracefully. This semi-set solitaire ring invites you to select a center stone measuring 12 by 6 millimeters, a size that balances bold presence with refined elegance.

Crafted from warm 18K rose gold, the band is shaped with subtle contours that cradle the stone securely once set, while the smooth finish ensures comfortable daily wear. The low-profile mounting keeps the diamond close to the hand, making it glove-friendly and ideal for stacking alongside other bands.

Each ring is meticulously finished in our Williamsburg studio, where artisan hands polish and inspect every curve to meet exacting standards. The rose gold’s soft glow complements the marquise’s dramatic shape, emphasizing its vintage-inspired charm without sacrificing modern wearability.

Our commitment to sustainability is reflected in the lab-grown diamond option, offering clarity and brilliance with a lighter environmental footprint.

This design suits those who appreciate architectural lines paired with a warm, tactile feel—perfect for hands that favor statement pieces with subtle comfort. Resizing is available to ensure a precise fit, crafted with the same care as the original design.
