Sunlight catches the elongated points of the marquise diamond, casting a slender, dramatic silhouette that draws the eye along the finger. This 6 x 3.5 mm lab-grown stone is securely nestled in a low-profile setting crafted from warm 14K yellow gold, designed for everyday grace without catching or lifting.

The band’s smooth finish and subtle accent stones enhance the diamond’s tapered drama while ensuring a comfortable fit that slides easily beneath gloves or sleeves. Each ring is meticulously hand-finished in our Williamsburg studio, where precision meets quiet durability in every facet and prong.

Our commitment to sustainability shines through the lab-grown clarity of the marquise diamond—ethically sourced with a fraction of the environmental impact of mined stones. This ring suits those who appreciate refined geometry paired with practical wearability, ideal for hands that favor slender, elongated shapes.

Should you need a custom size, resizing is handled expertly in-house to maintain the integrity of the setting and comfort fit. Typical lead times reflect our careful craftsmanship, ensuring your ring arrives ready for daily life.
