Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette that feels both bold and intimate. This three-stone semi-set ring frames a 10 x 5 mm marquise center with two delicate side stones, all poised on an 18K white gold band that balances presence with subtlety.

Crafted for everyday wear, the low-profile setting keeps the stones secure yet unobtrusive, while the comfort-fit shank ensures the ring settles naturally against the finger. Each element is hand-finished in our Williamsburg studio, where precision meets thoughtful design to accommodate daily life without compromise.

Our diamonds are lab-grown, offering a clarity and brilliance that honors both ethical sourcing and environmental mindfulness.

The elongated marquise shape visually lengthens the finger, making this ring especially flattering on slender hands or those who prefer a refined statement. Its three-stone layout adds dimension without bulk, ideal for stacking or wearing solo with ease.

Should you need a custom size, resizing is straightforward thanks to the solid 18K gold band and expert craftsmanship.
