Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, casting a slender, luminous shadow that feels like a whispered promise. This semi-set solitaire ring invites you to choose your own 8 x 4 mm center stone, allowing the distinctive shape’s tapered points to elongate the finger with subtle drama.

Crafted in 14K white gold with a delicate rose gold band option, the mounting balances refined strength with graceful minimalism. The low-profile setting keeps the diamond close to the hand, while the smooth comfort fit ensures it wears effortlessly every day. Each piece is meticulously finished and inspected in our Williamsburg studio, where precision meets quiet artistry.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both beauty and sustainability without compromise.

This solitaire suits those who appreciate a ring that feels intimate yet striking—ideal for stacking with slender bands or worn solo as a statement of personal elegance. Its shape and size work well on slender to medium fingers, enhancing natural hand lines without overwhelming.

Should you wish to resize or customize further, our Brooklyn studio offers attentive, pressure-free consultations to guide your choices.
