Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with a quiet elegance. This semi-set halo ring foundation in 18K yellow gold offers a warm, rich backdrop that enhances the stone’s dramatic shape without overwhelming it.

Crafted in our Williamsburg studio, the band is hand-finished to a smooth comfort fit, designed for daily wear with a low-profile setting that nestles close to the finger. The halo setting, ready to frame a 9 x 4.5 mm marquise center, will amplify the diamond’s natural brilliance while protecting its delicate points.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that combine clarity and sustainability without compromise. The warm glow of yellow gold complements the marquise’s vintage-inspired geometry, making it an ideal choice for those who appreciate artisan craftsmanship and subtle drama.

This ring suits hands that favor elongated shapes, enhancing slender fingers and pairing beautifully with stackable bands or a wedding band designed for close alignment. Its low profile ensures it remains glove-friendly and comfortable for everyday life.

Resizing is available to ensure a perfect fit, with careful attention to preserving the ring’s structural integrity and finish. Typical lead times reflect our bespoke approach, allowing for personalized adjustments and quality checks.
