Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set engagement ring foundation in warm 18K rose gold offers a refined stage for a 10 x 5 mm marquise center stone, framed by delicate accent diamonds that enhance its modern-minimal clarity and structure.

Crafted with precision in Williamsburg, the band’s smooth finish and subtle taper ensure a comfortable fit that sits low against the finger, ideal for everyday wear. The rose gold’s gentle blush complements the marquise’s dramatic shape without overwhelming its architectural elegance.

Each piece is designed with lab-grown diamonds, reflecting a commitment to ethical sourcing and sustainability without compromising brilliance or clarity. The semi-set style invites you to select a center stone that resonates personally, allowing for a truly bespoke expression.

Its slender profile and balanced accents make this mounting well-suited to hands seeking a confident yet understated statement, pairing effortlessly with stackable bands or worn solo. The low-profile setting also accommodates glove wear and daily movement with ease.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers expert care and consultation to ensure your ring fits perfectly. Typical lead times vary depending on stone selection and customization.
