Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a subtle, tapered brilliance that draws the eye along the finger’s natural line. This semi-set solitaire ring in 18K white gold offers a refined foundation, ready to cradle a 7 x 3.5 mm marquise stone with precision.

Crafted with a low-profile setting, the band balances sleekness and strength, ensuring the ring sits comfortably beneath gloves or daily wear. The polished white gold shank is shaped for a gentle comfort fit, designed to feel as natural as it looks.

Each piece reflects a commitment to sustainability through lab-grown diamonds, offering clarity and sparkle without compromise. This ring’s silhouette suits those who appreciate architectural elegance paired with subtlety, ideal for hands that favor slender, elongated forms.

Resizing is straightforward, handled expertly in our Williamsburg studio to maintain the integrity of the setting. Whether layered with other bands or worn solo, this mounting invites personal expression.
