Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of a marquise diamond, its tapered points drawing the eye along a graceful silhouette. This semi-set halo engagement ring foundation in warm 10K yellow gold awaits your choice of a 10 x 5 mm center stone, ready to frame it with a delicate halo that amplifies brilliance while maintaining a refined profile.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle taper that balances presence and wearability. The halo setting is meticulously soldered and polished to a smooth finish, ensuring the ring sits low enough for everyday ease yet high enough to catch light with every movement.

Each lab-grown diamond offers clarity and sparkle without the environmental cost of mining, reflecting a commitment to ethical jewelry that honors both beauty and conscience.

Designed for those who appreciate a statement piece that remains practical, this ring suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding band. Its low-profile setting slips easily under gloves and sleeves, making it an ideal choice for daily wear.

Should you need resizing or prefer a custom halo design, our Brooklyn studio offers personalized consultations to tailor your ring to your lifestyle and vision.
