Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of a marquise diamond, casting a slender, graceful shadow that seems to stretch beyond the finger. This semi-set engagement ring invites your choice of a 5 x 3 mm marquise stone, its pointed ends evoking a quiet drama and refined elegance.

Crafted from 18K white gold, the mounting features a delicate solitaire setting designed for everyday wear. The low-profile band curves smoothly, offering a comfort fit that slips easily beneath gloves or alongside stackable rings. Each piece is hand-finished in our Williamsburg studio, where meticulous inspection ensures a flawless surface and secure prongs.

Our diamonds are lab-grown, reflecting a commitment to ethical jewelry that honors both beauty and sustainability without compromise.

This ring suits those who appreciate subtle sophistication and a shape that elongates the hand, perfect for slender fingers or anyone drawn to architectural refinement. The semi-set design allows you to select a marquise diamond that resonates personally, making the ring uniquely yours.

Should you need resizing or guidance on stone selection, our Brooklyn studio team is ready to assist with care and expertise.
