Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger like a whispered secret. This semi-set halo engagement ring invites your choice of a 10 x 5 mm marquise center, framed by a delicate halo that amplifies its vintage-inspired sparkle.

Crafted in warm 14K yellow gold, the band is hand-finished in our Williamsburg studio with a low-profile setting that balances presence and comfort. The halo’s artisan prongs cradle the center stone securely while allowing light to dance freely, creating a subtle glow that complements daily wear without catching on fabric.

Each ring reflects our commitment to ethical jewelry: the marquise diamond you select will be lab-grown, offering clarity and brilliance with a smaller environmental footprint.

Designed for those who appreciate a refined silhouette, this ring suits slender to medium fingers, elongating the hand with its architectural shape. Its modest height and smooth band make it an excellent choice for stacking or pairing with a wedding band.

Should you need resizing, our Brooklyn studio offers personalized adjustments to ensure a perfect fit without compromising the ring’s integrity.
