Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated marquise diamond, casting a slender, fiery beam that dances across the hand. This three-stone engagement ring in 14K yellow gold frames the 9 x 4.5 mm center stone with two delicate side diamonds, creating a quiet narrative of balance and grace.

Each gem is securely nestled in a low-profile setting, polished to a soft sheen that complements the warm glow of the gold band. The comfort-fit shank curves gently beneath the finger, designed for everyday wear without interruption.

Crafted in Williamsburg, this ring features a lab-grown marquise diamond, chosen for its ethical clarity and sustainable origin—offering brilliance without compromise.

Its slender silhouette suits those who appreciate refined geometry and subtle drama, elongating the finger while remaining glove-friendly and stackable with other bands.

Should you need a custom fit, resizing is handled delicately in-studio to preserve the ring’s integrity and finish.
