Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a delicate shimmer that traces the curve of your hand. This three-stone semi-set engagement ring in 10K yellow gold frames an 8 x 4 mm marquise center, its pointed ends drawing the eye along a graceful line.

Handcrafted in Williamsburg, the band’s gentle curve and low-profile setting ensure a comfortable fit for everyday wear. Each prong is meticulously finished to cradle the stone securely while allowing light to flood the facets, enhancing the marquise’s signature brilliance and subtle drama.

Our commitment to sustainability is reflected in the lab-grown diamond’s clarity and ethical origin, offering a conscious choice without compromise on beauty or sparkle.

The ring’s slender band suits those who appreciate refined elegance and works beautifully alongside stacking bands or a wedding band. Its low profile makes it glove-friendly and ideal for hands that favor sleek, elongated shapes.

Should you need a custom fit, resizing is available with care to preserve the ring’s balance and integrity.
