Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the finger with a subtle, elegant drama. This semi-set three-stone ring offers a handcrafted foundation in warm 14K rose gold, its soft blush hue complementing the stone’s graceful shape.

Each band is shaped and finished in our Williamsburg studio, polished to a gentle sheen that feels smooth against the skin. The low-profile setting ensures everyday comfort while allowing light to dance across the marquise’s distinctive facets. The three-stone arrangement balances presence with wearability, ideal for those who appreciate refined detail without excess height.

Our diamonds are lab-grown, chosen for their clarity and ethical provenance, reflecting a commitment to sustainability without compromise on brilliance.

Designed for hands that value subtle statement, this ring pairs beautifully with stacking bands or stands confidently alone. Its slender 6 x 3 mm marquise shape elongates the finger, while the rose gold’s warmth suits a variety of skin tones and personal styles.

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