Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that seems to stretch beyond the finger. This semi-set engagement ring foundation in 14K white gold awaits your choice of a 10 x 5 mm marquise center, its pointed ends echoing a refined, tapered drama.

Hand-forged in our Williamsburg studio, the band’s subtle accents are meticulously crafted to complement the stone’s shape without overpowering it. The low-profile setting ensures a comfortable fit beneath gloves or daily wear, while the smooth finish reflects the quiet precision of artisan hands.

Each piece embraces the clarity and sustainability of lab-grown diamonds, aligning with a modern ethical approach to fine jewelry. The slender band suits those who appreciate a delicate balance between statement and subtlety, ideal for stacking or wearing solo.

Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio offers personalized consultations to tailor the ring to your lifestyle. Lead times are transparent and designed to respect your timeline.
