Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that seems to stretch the hand with quiet elegance. This semi-set halo engagement ring in 10K white gold frames a 10 x 5 mm marquise center stone, inviting you to choose a lab-grown diamond that balances fiery sparkle with architectural grace.

Crafted in Williamsburg, the band’s slender profile and low-set halo embrace the stone securely while maintaining a refined comfort fit. The polished white gold shank offers a cool, smooth touch against the skin, designed for everyday wear without catching on gloves or sleeves. Each piece is meticulously finished and inspected in-studio, ensuring the halo’s pavé diamonds align precisely to amplify the marquise’s signature pointed ends.

Our commitment to ethical jewelry is reflected in the lab-grown diamond’s clarity and sustainability, offering a conscious alternative without compromise. This ring suits those who appreciate a blend of vintage-inspired romance and modern craftsmanship, especially flattering on slender fingers or as a striking solitaire complement in a stack.

Resizing is available to ensure a perfect fit, with typical lead times tailored to your custom diamond selection and finishing preferences. Whether you visit our Williamsburg studio or begin your design journey online, we welcome you to explore this distinctive halo setting as a foundation for your unique story.
