Lab-Grown Diamond Engagement Ring

Light catches the marquise’s tapered points, casting a subtle, elongated sparkle that draws the eye along the finger’s natural line. This semi-set three-stone ring foundation in warm 18K yellow gold invites your choice of a 6 x 3.5 mm marquise center, framed by gently curved side stones that balance architectural drama with refined grace.

Each band is hand-shaped and polished in our Williamsburg studio, the low-profile setting designed for everyday wear without catching or discomfort. The smooth interior offers a comfort fit that feels like a second skin, while the secure prongs cradle your stones with artisan precision.

Crafted exclusively with lab-grown diamonds, this piece reflects a commitment to ethical jewelry that honors both clarity and conscience.

Its slender silhouette suits those who appreciate a ring that complements rather than dominates, ideal for stacking or wearing solo with understated elegance. The marquise’s distinctive shape elongates the finger, enhancing natural hand lines with a modern yet timeless geometry.

Should you need resizing or prefer a custom side stone selection, our Brooklyn studio offers personalized consultations to ensure your ring fits seamlessly into your life.
