Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a delicate dance of light across your hand. This three-stone engagement ring, set in warm 14K yellow gold, frames a 12 x 6 mm marquise center with two gently tapering side stones, creating a balanced, poetic composition.

Each diamond is carefully bezel-set to sit low against the finger, offering a sleek profile that slips comfortably beneath a glove or alongside other bands. The polished shank curves softly, finished by hand in our Williamsburg studio to ensure a smooth, comfort fit that invites daily wear.

Crafted exclusively with lab-grown diamonds, this ring reflects a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

Its elongated marquise shape visually lengthens the finger, ideal for those who appreciate a refined yet distinctive silhouette. The three-stone design carries a quiet symbolism of past, present, and future, making it a thoughtful choice for a meaningful journey.

Should you need a custom adjustment, resizing is handled delicately in-house to maintain the ring’s integrity and finish.
