Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate sparkle that seems to stretch beyond the finger. This semi-set engagement ring invites you to select a center stone that echoes your unique story, framed by a warm 10K yellow gold band that feels smooth and familiar against the skin.

Crafted with a low-profile solitaire setting, the band’s gentle curve ensures daily comfort and subtle elegance. Each piece is meticulously finished in our Williamsburg studio, where precision meets quiet artistry in every contour and polish.

Choosing a lab-grown diamond means embracing clarity and brilliance with a lighter environmental footprint, reflecting a commitment to ethical jewelry without compromise.

The narrow band suits slender to medium finger shapes gracefully, offering a refined foundation for the marquise’s dramatic, tapered points. Its modest height makes it glove-friendly and ideal for stacking with complementary bands.

Should you need resizing, our in-studio experts provide careful adjustments to ensure a seamless fit without disrupting the ring’s balance.
