Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, luminous silhouette that feels both bold and intimate.

This three-stone semi-set ring features an 8 x 4 mm marquise center, cradled in a 14K rose gold band shaped for everyday comfort. The low-profile setting keeps the stones close to the finger, reducing snagging while maintaining a confident presence. Each prong is hand-finished in our Williamsburg studio, ensuring precise alignment and a smooth touch against the skin.

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

The gentle curve of the rose gold band complements slender to medium finger shapes, while the three-stone design balances visual weight for those who appreciate subtle drama. Its streamlined silhouette pairs well with stacking bands or worn solo for a refined statement.

Resizing is available to ensure a tailored fit, with typical lead times of 4–6 weeks from consultation to completion.
