Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it reveals a striking balance of drama and refinement—an emblem of modern-minimal elegance. This semi-set engagement ring features a 9 x 4.5 mm marquise center designed to command attention with its sharp points and brilliant facets, framed by delicate accent stones that enhance its architectural clarity.

Crafted from 10K white gold, the band offers a cool, luminous backdrop that complements the diamond’s crisp geometry. The setting is thoughtfully low-profile, ensuring everyday comfort while maintaining a confident presence on the finger. Each piece is hand-finished in our Williamsburg studio, where precision meets quiet restraint in every detail.

Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising on brilliance or purity.

Ideal for those who appreciate clean lines and structured form, this ring pairs effortlessly with stackable bands or stands alone as a statement of refined taste. Its slim profile fits comfortably beneath gloves and is suited to slender or medium-width fingers seeking a distinctive yet wearable design.

Should you need adjustments, resizing is available to ensure a perfect fit, crafted with the same care as the original design. Typical lead times reflect our dedication to bespoke quality rather than mass production.
