Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated points of the marquise diamond, casting a slender, dramatic silhouette across the hand. This semi-set engagement ring features an 8 x 4 mm marquise center stone, designed to emphasize the shape’s graceful taper and vintage-inspired allure.

Crafted in 10K yellow gold, the mounting is engineered for everyday wear with a low-profile setting that keeps the diamond secure yet unobtrusive. The band’s smooth finish and subtle curvature ensure comfort, while the prongs cradle the stone with precision, allowing light to flood the facets for lively brilliance.

Each piece is thoughtfully made in our Williamsburg studio, reflecting a commitment to sustainable luxury through lab-grown diamonds that offer clarity and ethical provenance without compromise.

The slender marquise shape naturally elongates the finger, ideal for those seeking a ring that balances bold geometry with refined wearability. Its solitaire style pairs effortlessly with stacking bands or stands strikingly alone.

Should you need resizing, our in-house artisans provide careful adjustments to maintain the ring’s integrity and comfort.
