Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, tracing a delicate arc that seems to stretch the fingers with quiet elegance. This semi-set solitaire ring features a 7 x 3.5 mm marquise center, its pointed ends framed by a slender 10K white gold band that balances subtlety with presence.

Crafted in Williamsburg, the band is smoothly polished to a comfort fit, designed for everyday wear without catching or shifting. The low-profile setting keeps the diamond close to the hand, making it an ideal choice for those who appreciate refined geometry paired with practical grace. Each piece is meticulously inspected to ensure the prongs cradle the stone securely while allowing light to flood the facets.

Our diamonds are lab-grown, offering a clarity and brilliance that honors sustainability without compromise. This ring’s ethical foundation reflects a commitment to responsible craftsmanship rooted in Brooklyn’s creative spirit.

The marquise shape lends a vintage-inspired drama, elongating the finger and catching the eye with its distinctive, tapered points. Its solitaire design invites personal expression, whether worn alone or stacked with complementary bands. The semi-set style allows you to select a center stone that resonates with your vision.

Resizing is available to ensure a perfect fit, and the studio welcomes conversations about custom adjustments or alternative stones. Lead times are typically four to six weeks, reflecting the care poured into each creation.
