Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of an oval diamond, casting a gentle glow that seems to stretch beyond the stone itself. This semi-set halo engagement ring foundation invites your choice of a 12 x 10 mm oval center, known for its graceful silhouette that subtly elongates the finger.

Crafted from 18K white gold, the mounting is meticulously finished with a low-profile halo setting that balances brilliance with everyday wearability. Each prong and pavé detail is hand-inspected in our Williamsburg studio to ensure a seamless fit and comfort, designed to sit close to the hand without catching.

Our commitment to ethical jewelry shines through the option to pair this setting with a lab-grown diamond, offering clarity and sustainability without compromise. The cool white gold complements the stone’s glassy elegance, creating a refined canvas for your personal expression.

Ideal for those who appreciate a blend of artisan craft and modern design, this halo setting works beautifully with an oval stone’s natural elongation, flattering slender fingers and pairing effortlessly with stackable bands. Its modest profile also makes it glove-friendly for daily wear.

Should you need resizing or custom adjustments, our Brooklyn studio offers attentive care with typical lead times communicated upfront to ensure a smooth process.
