Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond, measuring 10 by 5 millimeters, draws the eye with its subtle drama and graceful taper. This solitaire semi-set ring offers a refined foundation crafted from 14K yellow gold, designed to cradle your chosen stone securely while maintaining a low profile that slips comfortably beneath daily gloves or sleeves.

Each band is hand-finished in our Williamsburg studio, polished to a satin sheen that balances understated elegance with durability. The mounting’s streamlined shape ensures wearability for everyday life, with a comfort fit that hugs the finger without bulk.

Our commitment to lab-grown diamonds means your center stone will shine with clarity and brilliance, created with a lighter environmental footprint and ethical transparency.

Ideal for those who appreciate a classic solitaire silhouette with a modern sensibility, this setting complements the marquise’s elongating effect on the hand and pairs effortlessly with stacking bands or a wedding ring.
