Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a path of subtle drama across the hand—an elegant gesture that feels both intimate and bold. This semi-set platinum band awaits your choice of a 12 x 6 mm marquise center, its slender prongs designed to cradle the stone with quiet strength.

Crafted in Williamsburg, the platinum setting offers a cool, weighty presence that balances durability with refined comfort. Its low-profile design ensures the ring sits close to the finger, making it an ideal companion for daily wear and effortless stacking. Each curve is polished to a soft gleam, reflecting the studio’s commitment to meticulous finishing and inspection.

Choosing a lab-grown diamond here means embracing clarity and brilliance without compromise—an ethical choice that aligns with a sustainable vision for fine jewelry.

The elongated marquise shape naturally elongates the finger, lending a graceful, architectural elegance that suits those who appreciate a blend of classic form and modern minimalism. Its slender silhouette pairs well with slender or average finger sizes, and the platinum band’s smooth interior offers a comfort fit that feels like a second skin.

Should you need resizing, the platinum band can be adjusted with care to maintain its sleek profile without disrupting the setting’s integrity.
