Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, graceful shadow across the hand. This three-stone semi-set engagement ring in 18K yellow gold frames a 7 x 3.5 mm marquise center with two gently tapered side stones, creating a balanced silhouette that feels both refined and approachable.

Crafted for everyday wear, the low-profile setting keeps the stones close to the finger, reducing snagging while maintaining brilliance. The warm glow of 18K yellow gold complements the marquise’s tapered drama, and the band’s subtle comfort fit ensures it settles naturally beneath the hand.

Each diamond is lab-grown, offering clarity and sparkle with a lighter environmental footprint, reflecting a commitment to ethical jewelry without compromise.

This design suits those who appreciate architectural elegance with a practical edge—ideal for slender or average finger sizes and stackable with complementary bands. Its streamlined form slips easily under gloves or sleeves, making it a versatile choice for daily life.

Should you need resizing, our Brooklyn studio handles adjustments with care to preserve the ring’s integrity and finish.
