Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a subtle, tapered glow that draws the eye along the finger. This semi-set halo engagement ring in 10K yellow gold frames a 6 x 3.5 mm marquise center with a delicate circle of smaller stones, enhancing its signature silhouette without adding bulk.

Crafted with a low-profile setting, the ring balances elegance and everyday practicality—its smooth shank designed for comfort and ease beneath gloves or alongside stackable bands. Each piece is meticulously finished in our Williamsburg studio, where precision meets a quiet, modern aesthetic.

Our commitment to sustainability is reflected in the lab-grown diamond’s clarity and ethical origin, offering brilliance without compromise. The warm hue of 10K yellow gold complements the marquise’s vintage-inspired shape, making it a refined choice for those who appreciate subtle drama in daily wear.

Sized to fit comfortably, this semi-set allows you to select a center stone that matches your vision, with expert resizing available to ensure a perfect fit. The halo setting adds a protective frame, enhancing durability for an active lifestyle.
