Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise diamond, casting a slender, dramatic silhouette that stretches gracefully across the finger. This semi-set solitaire ring invites you to select a 9 x 4.5 mm marquise center stone, known for its tapered drama and ability to visually lengthen the hand.

Crafted from 10K white gold, the mounting features a delicate yet secure prong setting designed in our Williamsburg studio. The band’s subtle taper and smooth finish ensure a comfortable fit that sits low enough for everyday wear without sacrificing presence. Each piece is meticulously hand-finished and inspected to meet exacting standards of craftsmanship.

Our commitment to sustainability is reflected in the use of lab-grown diamonds, offering clarity and brilliance with a smaller environmental footprint.

Ideal for those who appreciate a refined, architectural shape paired with a minimalist band, this ring complements slender fingers and layers effortlessly with other stackable bands. Its low-profile setting makes it glove-friendly and suited for daily life.

Should you need resizing or prefer a custom stone cut, we welcome consultations to tailor the ring precisely to your vision and lifestyle.
