Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval diamond, its elongated silhouette casting a subtle glow across the hand. This three-stone semi-set engagement ring in 18K yellow gold offers a warm, rich foundation for a 6 x 4 mm center stone of your choice, inviting personal expression.

Each band is meticulously crafted in our Williamsburg studio, where the smooth, comfort-fit shank is hand-polished to a soft luster. The three-prong settings are designed to hold stones securely while maintaining a low profile, allowing the diamonds to sit close to the finger for everyday wearability.

Our commitment to ethical jewelry is reflected in the lab-grown diamonds you select—offering clarity and brilliance with a smaller environmental footprint.

The elongated oval shape naturally elongates the finger, flattering a variety of hand sizes and shapes. Its three-stone arrangement balances classic elegance with modern simplicity, making it ideal for stacking or wearing solo.

Should you need resizing, our in-house artisans ensure a seamless adjustment without compromising the ring’s integrity.
