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 engagement ring invites you to select a center stone measuring 9 by 4.5 millimeters, a shape known for its tapered points and elegant elongation that visually lengthens the hand.

Crafted from 18K yellow gold, the mounting is designed with a refined solitaire setting that balances bold presence with everyday wearability. The band’s smooth finish and secure prongs ensure comfort and durability, while the low-profile design keeps the ring glove-friendly and ideal for stacking alongside wedding bands or delicate accessories.

Each piece is meticulously shaped and polished in our Williamsburg studio, where artisan hands inspect every detail to meet exacting standards. The semi-set format offers flexibility, allowing you to choose a lab-grown diamond that reflects your personal vision with clarity and brilliance.

Lab-grown diamonds provide a conscious alternative, reducing environmental impact without compromising on the luminous fire and precision cut that define fine jewelry.

This ring suits those who appreciate a statement silhouette paired with subtle craftsmanship—a piece that transitions seamlessly from daily life to special moments.
