Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its tapered points drawing the eye along a refined, architectural line. This semi-set engagement ring foundation in warm 18K rose gold offers a sleek, modern-minimal frame designed to highlight an 8 x 4 mm center stone of your choice.

Crafted in Williamsburg, the band’s subtle accents balance clarity with structure, while the low-profile setting ensures everyday comfort and ease beneath gloves or alongside stackable bands. Each piece is meticulously finished by hand, polished to a satin sheen that complements the rose’s gentle glow.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, marrying sustainability with exceptional clarity and brilliance. This mounting suits those who appreciate confident design with a quiet presence, especially on slender to medium fingers where the marquise shape elongates the hand gracefully.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure a seamless fit without compromising the ring’s clean lines. Typical lead times allow for thoughtful customization and expert finishing.
