Lab-Grown Diamond Engagement Ring

Imagine the gentle elongation of a marquise diamond catching morning light, its tapered points drawing the eye along the hand’s natural curve. This semi-set solitaire ring offers a poised foundation for a 6 x 3.5 mm marquise center, ready to be paired with a stone that balances architectural grace and delicate drama.

Crafted in 14K yellow gold, the mounting features a refined solitaire setting designed for everyday wear. The band’s subtle taper and low-profile prongs ensure comfort beneath gloves or alongside stackable bands, while the polished finish reflects light with a soft glow. Each piece is meticulously shaped and inspected in our Williamsburg studio, where precision meets quiet artistry.

Our commitment to ethical jewelry is reflected in the choice of lab-grown diamonds, offering clarity and brilliance with a lighter environmental footprint.

This ring suits those who appreciate a slender silhouette and a setting that honors the stone’s unique shape without distraction. Its semi-set state invites you to select a marquise diamond that resonates personally, making the design truly your own.

Should you need resizing or guidance on selecting the ideal stone, our Brooklyn studio team is here to assist with care and expertise.
