Lab-Grown Diamond Engagement Ring

Sunlight catches the slender silhouette of a marquise diamond, its tapered points tracing a delicate arc that seems to elongate the hand with quiet elegance. This semi-set solitaire invites you to choose a 6 x 3 mm lab-grown marquise, known for its graceful, vintage-inspired shape that balances brilliance with a subtle architectural edge.

Crafted in warm 10K yellow gold, the mounting features a refined prong setting designed to hold the stone securely while maintaining a low profile that slips comfortably beneath daily gloves or sleeves. The band’s gentle curve and polished finish reflect the Brooklyn studio’s commitment to tactile ease and understated sophistication.

Each diamond is ethically cultivated, offering clarity and sparkle without compromise to the environment or community. This ring suits those who appreciate a romantic silhouette that pairs effortlessly with stackable bands or stands alone as a statement of personal style.

Should you wish to adjust the fit, resizing is available to ensure the ring feels as natural as the moment it celebrates. Lead times reflect careful handcrafting in Williamsburg, where every piece is finished and inspected with exacting care.
