Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the hand. This semi-set halo engagement ring invites you to choose a 7 x 3.5 mm marquise stone, whose graceful shape lends a subtle drama and elongation to the finger.

Crafted in warm 18K yellow gold, the band is polished to a soft glow that complements the diamond’s fire. The halo setting, designed in our Williamsburg studio, surrounds the center with a ring of smaller stones, enhancing brilliance while maintaining a low-profile silhouette that slips comfortably beneath gloves or daily wear.

Each ring is finished by hand, inspected for precision, and designed with a comfort fit that balances elegance with everyday ease. The semi-set design allows you to select a lab-grown diamond of exceptional clarity and ethical provenance, reflecting a commitment to sustainability without compromise.

This style suits those who appreciate romantic details paired with modern craftsmanship—ideal for slender fingers or anyone seeking a ring that feels both intimate and striking. The halo’s gentle sparkle layers beautifully with stacking bands or stands alone as a statement of quiet confidence.

Resizing is available to ensure a perfect fit, and our studio offers a pressure-free consultation to guide your selection and customization.
