Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an oval diamond, casting a gentle glow that seems to stretch beyond the stone’s edges. This semi-set halo ring foundation invites your choice of a 12 x 10 mm oval center, its shape known for elongating the finger with graceful, soft drama.

Crafted from 18K white gold, the mounting features a delicate halo setting designed in our Williamsburg studio, where each prong and bezel is meticulously hand-finished to ensure a secure yet refined silhouette. The low-profile design balances presence with everyday comfort, making it a natural companion for daily wear.

Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint.

Ideal for those who appreciate artisan detail and a ring that layers beautifully with wedding bands or stackable accents, this setting complements a variety of hand shapes and sizes without overwhelming.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers personalized consultations to ensure a flawless fit.
